D. Raj, Parthasarathy, V., Rao, S. N., and Dr. Maneesha V. Ramesh, “Performance Assessment of an Extremely Challenged Mobile Infrastructure Network over the Oceans”, in Proceedings of the 18th International Conference on Distributed Computing and Networking, 2017.[Abstract]


A novel cost-effective network architecture for providing Internet connectivity to marine fishermen has been successfully prototyped by our research center. A pilot deployment is in progress in a coastal Indian village. This will improve the quality of life of the financially constrained marine fishermen who spend 5-7 days offshore on average for a single fishing trip; it will also help in their safety and security. The architecture employs multiple long range Wi-Fi (LR Wi-Fi) based infrastructure networks stitched together as backhaul. The access network consists of Ethernet and Wi-Fi mesh. The fishermen connect to the on board Wi-Fi access point cum router using their smart phones and are able to use all the apps and services on their smart phone. While the primary infrastructure network uses onshore base stations, the secondary infrastructure networks use boats as mobile base stations. Three field trials were conducted over the ocean using one onshore base station and two mid-sized boats known as trawlers. The performance of both primary and secondary infrastructure networks was assessed during these field trials. This paper describes the impressive results obtained in assessing the performance of the secondary infrastructure network.

According to the World Health Organization, an estimated 17 million people die annually due to cardiac disease, which accounts for 30% of the global deaths. Current studies on cardiac diseases indicate that 15% of the people have Left Anterior Hemiblock (LAHB), which ranks third after Right Bundle Branch Block (RBBB) and Left Bundle Branch Block (LBBB). To our knowledge, a reliably consistent disease detection and warning algorithm is not currently available for LAHB although various ECG morphologies can be monitored for real-time detection of LAHB. The objective of this research is to develop a real-time detection and warning of LAHB. The presented work describes the design of a weighted feature-based disease classification algorithm, which can be run in a resource constrained mobile environment for effective realtime diagnosis. The testing and evaluation of the algorithm indicates that it is able to detect LAHB with an accuracy of 95.3% and specificity of 100%. © 2016 IEEE.

A. M. S, K, A., Devidas, A. R., and Dr. Maneesha V. Ramesh, “A Smart Positioning System for Personalized Energy Management in Buildings”, in 2016 International Conference on Wireless Communications, Signal Processing and Networking (WiSPNET), 2016, pp. 742-747.[Abstract]


Energy consumption in official buildings contributes to 42% of total energy generation in India. The key features in commercial buildings are usage of high energy consuming devices, long duration of usage of electrical equipments, large population density and large equipment density compared with the floor area usage in houses. Hence this problem has motivated to perform research on energy management in official buildings. The individuals in these buildings mostly have unique authority on most of the equipments they handle, and they have their own comfort level requirement based on the context and the equipment availability. Therefore, to devise an effective energy management solution it is required to consider personal requirements with highest priority than the community requirements. Hence in this research work we design and develop systems & solutions needed for Personalized Energy Management (PEM). Our proposed system is developed to capture the spatio-temporal data of context and electrical usage pattern for each individual with bare minimum sensors. To address this challenge, we proposed a smart positioning system (SPS) for personalized energy management. In SPS, we have developed an Real time Smart Positioning System (RSPS) algorithm for integrating electrical map and sensing coverage of electrical appliances inside a building to position the individual in real-time with respect to each of the electrical appliances. Using SPS, the current position of an individual inside the building is determined along with the position of nearby electrical appliances to automate the appliance usage. This is performed using the proposed RSPS algorithm where real-time mapping of electrical map, sensing coverage of nearby equipments, signal strength, and pattern of individual requirements are used to control usage of equipments related to individual's choice. Experimental analysis of the RSPS algorithm on our prototype has been performed and the results showed that it requi- es a minimum of 2 coverage and it is not required to have 3 coverage as in other localization algorithms. Under the above condition of 2 coverage this algorithm was able to achieve an accuracy of 90%.

Conference Paper

S. Kumar, Rangan, P. V., and Dr. Maneesha V. Ramesh, “Poster: Pilot Deployment of Early Warning System for Landslides in Eastern Himalayas ”, in Proceedings of the Annual International Conference on Mobile Computing and Networking, MOBICOM, 2016, vol. 03-07-October-2016, pp. 97-98.[Abstract]


Using wireless networks to connect and communicate between geological sensors is a more scalable and suitable way for designing landslide monitoring and warning system for larger areas spanning many acres. Added to this, if the system has the capability to function in solar power, then it becomes autonomous system with self-organizing and self-healing networks. But high terrain, steep slopes, dense vegetation and lack of light during monsoon season to generate solar power pose serious challenges to develop such an autonomous system with good wireless coverage. This paper is about efforts to design, develop and deploy one such landslide warning system in eastern Himalayas. Pilot deployment is already in place and full deployment is under progress.

Nowadays wireless sensor networks are implemented in a variety of fields to obtain real-time measurements. These networks are comprised of small, low cost devices called wireless sensor nodes (WSN). There are different types of wireless sensor nodes available in the market. Based on the requirements, wireless sensor nodes can be selected for each application. Power consumption is a major aspect in developing wireless sensor applications. In this paper, analysis of power consumption in different sensor nodes is conducted based on algorithms with different complexities. The experimental analysis results show that at a particular input current limit, Waspmote consumes 15% less power than MICAz mote in the case of O (1), 11.04% less in the case of O (n), 7.6% less in the case of O (n2), 3.9% less in case of O (log n) and 18.06% less in case of O (m+n)complex algorithms.

Remote health monitoring and delivery through mobile devices and wireless networks offers unique challenges related to performance, reliability, data size, power management, and analytical complexity. We present a multi-layered architecture that matches communication performance to medical importance of data being monitored. The priority of vital data and the context of sensing are used to select the communication medium and the power management policies. Further smartness is introduced into data summarization by employing a severity level quantizer, followed by a consensus abnormality motif discovery and an alert mechanism that prioritizes doctors' consultative time. We also present our successful implementation of the above multi-layered architecture in a system developed to remotely monitor cardiac patients.

Consistent power and cost effective health monitoring has become the need of the hour especially for the unstable, chronically and critically ill. Here we present a novel architecture and algorithmic methodology combining the sensing subsystem, symptom summarization, and data transmission. Physiological parameters from multiple sensors feed into a severity quantizer and a subsequent multiplexer, the output of which is processed by the RASPRO engine to rapidly discover and alert any health criticalities. The architecture is optimized for communication and energy performance, and the algorithms result in lucid presentations to physicians. The whole system is the result of close collaboration between engineering and medical teams at one of the best known multidisciplinary universities, building on a multi-terabyte more than a million patient Amrita Hospital Information System (HIS) database, and is being readied for deployment on a large telemedicine network of more than 60 nodes in the Indian subcontinent and parts of Africa.

Conference Paper

S. Shaji, Dr. Maneesha V. Ramesh, and Menon, V. N., “Real-time processing and analysis for activity classification to enhance wearable wireless ecg”, in Proceedings of the Second International Conference on Computer and Communication Technologies, 2016.[Abstract]


Health care facilities of our rural India are in a state of utter indigence. Over three-fifths of those who live in rural areas have to travel more than 5 km to reach a hospital and the health care services is becoming out of reach for the economically backward society of India. Currently, as the rural community experiences about 22.9% of death due to heart diseases [1], there is a need to improve the remote ECG monitoring devices to cater the needs of rural India. The existing wearable ECG devices experience several issues to accurately detect the type of heart diseases due to the presence of motion artifacts, and to warn the doctor during critical conditions. Hence, even though wearable devices are finding their place in today’s healthcare systems, the above mentioned issues discourages a doctor in depending upon it. So to enhance the existing wearable ECG device, a context aware system was designed to collect the BMA (Body Movement Activity). In this research work an innovative BMA classifier has been designed to classify the physical activities of users, from the real-time data received from context aware device. The test results of the BMA classifier integrated with the complete system shows that algorithm developed in this work is capable of classifying the user activity such as walking, jogging, sitting, standing, upstairs, downstairs, and lying down, with an accuracy of 96.66%.

Smart distribution grids will be a combination of existing electrical networks controlled by distributed software applications communicating via communication networks. This means that not only the reliability of individual technologies are crucial, but the interoperability is also pivotal for the robustness of the smart distribution network. These individual research areas (electrical network, distributed software controller and communication network) have their corresponding fault handling strategies and several proven solutions exist to ensure reliability. The objective of our work is to integrate the solutions from these individual technologies. We focus on the interoperability and integration of individual fault handling strategies that are essential for improving the reliability and robustness of the overall smart distribution network. In this paper, we describe our approach in creating a single solution from the existing individual strategies to create a robust smart distribution network. We also present the details of the demonstrator design that is being built to evaluate our approach.

Balaji Hariharan, Rangan, V. P., Surendran, S., Rekha, P., Devi, R. D. Arya, and Dr. Maneesha V. Ramesh, “Delay and energy optimization in multilevel balanced WSNs for landslide monitoring”, in Global Humanitarian Technology Conference (GHTC), 2016, 2016.[Abstract]


In most of the real world wireless sensor network deployments, the energy utilization is a critical factor as the nodes are battery powered. In most of the real-world deployments it is observed that the sensing subsystem consumes higher power. In order to extend the lifetime of such systems it is required to reduce the sensing energy than communication energy. We have deployed a system for monitoring Landslides in India consists of 150 geo-physical sensors and used solar panels to power these sensor nodes. The decision making in favor of Landslide occurrence is based on the maximum values obtained from the high priority sensors. As this maximum value is not frequently changing in the deployment, locating the sensor node with maximum value allows us to switch off the other sensors for a predetermined period of time. This work proposes an optimal balanced network topology for delay minimization by parallelizing data aggregation operation in each sub-network. The sensor node switch off schemes on the top of delay minimized topology enables the optimal utilization of the available solar power. The analysis of these mechanisms shows that, more number of nodes can be powered with the available source of energy and can increase the network life time.

Conference Paper

S. N. Rao, Dr. Maneesha V. Ramesh, and Rangan, V., “Mobile infrastructure for coastal region offshore communications and networks”, in Global Humanitarian Technology Conference (GHTC), 2016, 2016.[Abstract]


Marine fishermen risk their lives when they go as far as 120 km from the shore on a fishing trip lasting 5-7 days. They are completely cut off from the mainland. Cellular coverage exists only up to 12-15 km from the shore. In emergency situations, the fishermen have no way to call for help. Even under normal conditions, prolonged isolation from their family and friends causes mental depression. Since the marine fishermen are not economically well off especially in the developing countries, there has not been much commercial interest in addressing this problem. It is not seen as a profitable business proposition. However, addressing this problem will benefit the marine fishermen community immensely. Our center conducted interviews with several fishermen to understand this problem and came up with a cost-effective solution. The solution enables the fishermen to use the smart phones which they own already to get internet at sea using Wi-Fi. The Access Point (AP) on the boat connects over Ethernet to an onboard gateway to long range Wi-Fi backhaul network. The onshore base station is installed on a tower at a height of 50-60 m. Boats are also used as mobile base stations to extend the range of the network. This solution, when tested over the Arabian Sea, provided a range of 40+ km in the first hop and 20+ km every subsequent hop. This network can be operated on a cooperative community basis by the fishermen community at reasonable per capita CAPEX and OPEX. A pilot deployment is in progress in a coastal village community in Kerala, India, to gain operational experience.

Dr. Maneesha V. Ramesh, Mohan, R., M Kumar, N., Brahmanandan, D., Prakash, C., Lalith, P., M Kumar, A., and Ramkrishnan, R., “Micro water distribution networks: A participatory method of sustainable water distribution in rural communities”, in Global Humanitarian Technology Conference (GHTC), 2016, 2016.[Abstract]


Water scarcity has been a major thrusting issue in rural India, warrantinga high demand to design and implement different water distribution networks for easy and efficient use of existing water sources. Both macro and micro level systems exist of which, macro level water distribution networks have higher capital and maintenance costs. This is due to its size and the remote beneficiaries to which it caters. This paper describes the design of one such water distribution system in two rural villages in India whose design considerations includes the local community needs, availability of labor, local resources, climate, cost, and time for implementation. This paper also compares the micro and macro water distribution network's impact on sustainability. Sustainability is defined in terms of water wastage, usage rate, source capacity, total network length, cost of deployment, source recharge, and the network leakage rate. The paper discusses the water distribution projectscompletedin a village in Orissa and in a village in Rajasthan (two states in India) where all households were given 24/7 access to clean and safe drinking water for more than a year. The paper also draws insights on the socio-economic impact of the project carried out in these two states.

Landslides are one of the major natural disasters and an early detection of landslide can be achieved by identifying the landslide triggering vibrations recorded using a geophone network. The major research challenges in this effort are network energy consumption, noise removal and development of a wireless network for transmitting the captured signals. This paper presents design and testing of a wireless smart geophone network with enhanced signal processing capability at the site for recording and analyzing geophone signals. The system has the capability to detect landslide induced signals and remove different types of noises produced by footsteps, vehicular movement, rainfall, and stream flow, and transmit the event data to a local processor. For this purpose, a simple and cost effective Arduino based data acquisition system with geophone inputs is developed. This system helps in reducing the system energy conception and is highly reliable, low cost compared to other traditional systems. This paper mainly focuses on the hardware design of sensor system and algorithms for identifying the characteristics of geophone signals for detecting landslide induced seismic signals. The characteristics of geophone signals for different seismic events recorded by the system are also provided.

A. R. Devidas and Dr. Maneesha V. Ramesh, “Power theft detection in microgrids”, in SMARTGREENS 2015 - 4th International Conference on Smart Cities and Green ICT Systems, Proceedings, 2015, pp. 342-349.[Abstract]


Theft of electricity amounts to 1.5% GDP, of most of the developing nations like India. Hence there is a great need to detect power thefts in developing nations. In this paper, we have proposed a wireless network based infrastructure for power theft detection which caters to other functional requirements of the microgrid such as renewable energy integration, automatic meter reading etc. Algorithm for power theft detection (PTDA) which is proposed in this paper, works in the distributed intelligent devices of the microgrid infrastructure for power theft detection. The coordinated action of intelligent devices with PTDA in the microgrid infrastructure enables not only the detection of power theft, but the localization of power theft in the micro-grid. PTDA increases the 1) cost of communication 2) energy consumption of intelligent devices 3) packet latency, if any critical data is piggy backed with power theft data in micro-grid. To solve these issues, we have proposed EPTDNA (Efficient Power Theft Data Networking Algorithm) which uses the frequency of power theft detection and average power draw for power theft, for the efficient routing of power theft. The performance analysis and results given in this paper shows how EPTDNA solves the major issues with PTDA.

Several challenges exist in developing smart buildings such as the development of context aware algorithms and real-time control systems, the integration of numerous sensors to detect various parameters, integration changes in the existing electrical infrastructure, and high cost of deployment. Another major challenge is to optimize the energy usage in smart buildings without compromising the comfort level of individuals. However, the success of this task requires in depth knowledge of the individual and group behaviour inside the smart building. To solve the aforementioned challenges, we have designed and developed a Smart Personalised System for Energy Management (SPSE), a low cost context aware system integrated with personalized and collaborative learning capabilities to understand the real-time behaviour of individuals in a building for optimizing the energy usage in the building. The context aware system constitutes a wearable device and a wireless switchboard that can continuously monitor several functions such as the real-time monitoring and localization of the presence of the individual, real-time monitoring and detection of the usage of switch board and equipment, and their time of usage by each individual. Using the continuous data collected from the context aware system, personalized and group algorithms can be developed for optimizing the energy usage with minimum sensors. In this work, the context aware system was tested extensively for module performance and for complete integrated device performance. The study found the proposed system provides the opportunity to collect data necessary for developing a personalized system for smart buildings with minimum sensors.

Over the past decade, experimentation for wireless sensor network (WSN) has been widely used to enrich the learning experience of educators and learners. Our remote triggered WSN laboratory is a multi-set, multi-group, WSN experimental setup that provides an intuitive web-based interface to carry out remote experimentation as well as code editing by registered users. This paper presents a multi-level time based scheduling algorithm for our lab which provides optimum utilization, performance and service.

Energy efficiency and delay optimization of WSN testbed are ensured in the design which employs TDMA and state transition schemes. We have implemented and tested two approaches for energy efficiency namely an on demand scheduling and a TDMA based approach which incorporates state transition and CDMA. The performance evaluation result shows that 78% power consumption has been reduced in second approach compared to first. The paper details the implementation of energy efficiency with dynamic scheduling for our real-time remote triggered WSN.

Ramesh, “A Low Cost Remote Cardiac Monitoring Framework for Rural Regions”, in MobiHealth 2015: 5th EAI International Conference on Wireless Mobile Communication and Healthcare - "Transforming healthcare through innovations in mobile and wireless technologies", London, Great Britain, 2015.[Abstract]


Cardiovascular diseases in rural developing countries take a large toll of human lives, due to inadequate quality health care facilities and their limited reach to the patients. The burgeoning population of developing nations make the lin- ear organic scaling of health care facilities impractical to cater the diverse rural geography. Hence it is imperative to scale the health care facilities through wireless communi- cation technologies in an aordable manner. Timely anal- ysis of ECG data is critical for early diagnosis and treat- ment of several cardiovascular diseases. With this aim, a wearable wireless ECG monitoring framework, named as Amrita-Spandanam was designed. This framework consist of a patient wearable device and a patient smart phone with Amrita-Spandanam application, enabling a doctor/hospital to monitor the remote patient through his internet con- nected mobile phone or web browser. The framework does the post analysis of the ECG signal using a backend server to disseminate warnings to the doctor and the patient. Sev- eral de-noising algorithms were applied to the acquired ECG signal prior to this post analysis. The framework was imple- mented successfully enabling real time remote monitoring of the cardiac patients in rural villages.

Wearable ECG monitoring is becoming a convenient way for patients as well as doctors, in tracking and diagnosing heart diseases among large population in rural areas. Wear- able ECG devices along with the smartphones are used to capture and transmit ECG data to hospitals where medi- cal practitioners diagnose and make suitable interventions. ECG electrode cable misplacement poses signicant chal- lenge when untrained population is the end-user. We present a real-time lead misplacement detection system for Mason- Likar lead conguration to provide immediate feedback to patients. It reduces chances of pseudo-disease diagnosis as well as the need for technicians to conrm the validity and quality of captured ECG data. The eld test results show that six dierent Mason-Likar electrode misplacement can be detected and dierentiated from a normal one with a condence value p=0.05.

Dr. Maneesha V. Ramesh, Mohan, N., and Devidas, A. Remanidevi, “Micro grid architecture for line fault detection and isolation”, in Smart Cities and Green ICT Systems (SMARTGREENS), 2015 International Conference on, 2015.[Abstract]


One of the major problems power grids system face today is the inability to continuously deliver power at the consumer side. The main reason for this is the occurrence of faults and its long term persistence within the system. This persistence of faults causes the cascading failure of the system, thereby adversely affecting the connected loads. Traditional methods of fault isolation cause the shutdown of power to a large area to maintain the system stability. Today, localization of faults and its isolation is doing manually. Therefore, a localized fault recovery mechanism is very essential to maintain the system’s stability after the occurrence of a fault. In this paper, we have developed fast fault detection and isolation mechanism for single phase to neutral line fault in a three phase islanded micro grid scenario. The fault detection and isolation during the islanded operation mode of a micro grid is very critical, since bidirectional power flow is present. The fault detection mechanism we developed can detect and isolate the fault within a few milliseconds and localize the fault within a two second delay for both in single and bi-directional power flow scenarios. The proposed system is capable of locating the exact faulted segment with the aid of the communication network integrated into the power grid. The implemented system was tested with different ranges of fault current and the analysis showed that the proposed system could localize the fault with less than a two second delay.

Most of the critical challenges seen in the past decades have impacted citizens in a global way. Given shrinking resources, educationists find preparing students for the global market place a formidable challenge. Hence exposing students to multi-lateral educational initiatives are critical to their growth, understanding and future contributions. This paper focuses on European Union’s Erasmus Mundus programs, involving academic cooperation amongst international universities in engineering programs. A phased undergraduate engineering program with multiple specializations is analyzed within this context. Based on their performance at the end of first phase, selected students were provided opportunities using scholarship to pursue completion of their degree requirements at various European universities. This paper will elaborate the impact of differing pedagogical interventions, language and cultural differences amongst these countries on students in diverse engineering disciplines. The data presented is based on on the feedback analysis from Eramus Mundus students (N=121) that underwent the mobility programs. The findings have given important insights into the structure of the initiative and implications for academia and education policy makers for internationalizing engineering education. These included considering digital interventions such as MOOCs (Massive Open Online Courses) and Virtual Laboratory (VL) initiatives for systemic reorganization of engineering education.

Urinary Incontinence is the most common health problem in old people, autistic kids and diabetic patients with significant social and economic impact in the quality of life. According to WHO, 20 million people are affected by Urinary Incontinence. This paper proposes an integrated architecture to continuously monitor the patients' bladder and remotely trigger the wireless artificial sphincter system using wireless power transfer in real time. After analysis, a few Ionic Electro Active Polymers (EAP) were selected to physically control the urethra. Possible designs using EAP polymer for urethra control are elaborated in this paper. This paper analyzes the major challenges of wireless power and data transfer and its impact on the design of the complete system. The proposed system provides a solution to continuously monitor the bladder and send alert messages to the control system that's on the patient's body. On receiving these alerts, patients' will remotely trigger the artificial sphincter control system to release the urine from their bladder. Thus the patients or caregivers can monitor the pressure inside their bladder and control urinal flow remotely by opening and closing the ionic EAP clip from outside. The system design has been simulated and tested with its different parameters and its results are discussed in this paper.

The high computational complexity of text classification is a significant problem with the growing surge in text data. An effective but computationally expensive classification is the k-nearest-neighbor (kNN) algorithm. Principal Component Analysis (PCA) has commonly been used as a preprocessing phase to reduce the dimensionality followed by kNN. However, though the dimensionality is reduced, the algorithm requires all the vectors in the projected space to perform the kNN. We propose a new hybrid algorithm that uses PCA & kNN but performs kNN with a small set of neighbors instead of the complete data vectors in the projected space, thus reducing the computational complexity. An added advantage in our method is that we are able to get effective classification using a relatively smaller number of principal components. New text for classification is projected into the lower dimensional space and kNN is performed only with the neighbors in each axis based on the principal that vectors that are closer in the original space are closer in the projected space and also along the projected components. Our findings with the standard benchmark dataset Reuters show that the proposed model significantly outperforms kNN and the standard PCA-kNN hybrid algorithms while maintaining similar classification accuracy.

The deployment of a wireless sensor network for real-time monitoring applications encounters numerous challenges. In a typical outdoor scenario the propagation of the radio signal can be affected by several factors like the rainfall, foliage, path loss effect and fading effect. These factors can confront dynamic changes in link quality which will affect the packet delivery rates and can result in the failure of the system. This paper presents an optimized frequency selection for any wireless sensor networks which can enhance the packet delivery ratio at any worst environmental scenarios through a simulated framework in QualNet 5.0.2.

Wireless sensor network deployed for any outdoor applications confronts link variations. The outdoor deployment can be appallingly affected by the precipitous change in the environmental conditions. The effect can vary accordingly with a single hop and a multi hop sensor network. In this paper, we analyze the impact of propagation factors such as shadowing, fading, foliage and rainfall on the link quality, received signal strength and packet reception rate. Then using a packet oriented simulation tool, Qualnet 5.0.2 a simulation framework was created to analyze the aftermath of the aforementioned propagation factors' separate as well as integrated effect on the signal quality. The models developed from the simulation are tested and assessed with the data received from the real time wireless sensor network system for landslide monitoring, deployed at Munnar, India. © 2014 IEEE.

Statistics show that the figure of new cancer cases and deaths reported each year are increasing considerably. The current situation demands an efficient targeted drug delivery system that enables localized drug administration which can be externally controlled. This paper proposes a remotely triggered targeted drug delivery system that is capable of providing drugs to multiple patients in a periodic basis and works according to the instructions transmitted from the external transmitter module. We present the characteristics and challenges in the propagation of Radio Frequency (RF) signals through different body tissues from the perspective of targeted drug delivery system so that the analysis can lead to the selection of optimum frequency needed for in-body communication. This paper focuses on the design of an implantable drug delivery system, based on the optimum frequency obtained from the simulation results.

One of the major problems, which the Indian electrical grid faces, is the lack of an efficient power management scheme. The proposed communication terminology supports the management of power in the home environment. Real time awareness is provided to the customers regarding extra power consumption. In peak power consumption periods, the consumer can chose to incur the financial charges by using all their home appliances or be supported to operate any appliance they wish by switching off some other lower priority appliances. These smart electrical homes also support authorities to control the extra power requirement during peak hours. © 2013 IEEE.

One of the major challenges faced by Indian power grid system are the excess use of energy and that results in the imbalance in the power generated and power consumed. The utility regulates the amount of consumption by introducing power cuts and time of use billing methods leading to decrease in the comfort level of consumers. A design for a smart control device, for efficient use of stored renewable energy, is proposed in this paper. The proposed system has a number of aspects. Firstly, this proposed system collects and analyses user consumption data. Dependent on the data the system makes a decision on the source of power to be made available: either renewable power from a battery or power from the grid. The system also calculates the amount of power to be stored, in a storage device. In addition, the system is able to make decisions on who gets priority to continue receiving power in the case of power shortage/failure. We simulated some of the basic system capabilities to switch the source of power depending on: the peak time, consumption of user, and the amount of battery power remaining. The results show that dependency of power from the grid is reduced and by setting priority of device, continuity of service is achieved. Our results indicate that power dependency from the grid can be reduced to 70-80% during peak hours and continuity of service can be achieved for critical devices during power failure. © 2013 IEEE.

Electricity usage is increasing day by day due to the changing life style of home user and an increase in appliances in the home area network. Our proposed home energy management system for home users will monitor, manage and control the usage of home appliances, by reducing the monthly electricity bill. The proposed wireless architecture consists of an appliance control device called Wireless Enabled Electricity Manager (WEEMAN) installed next to a switch board or every device/appliance in a room. The central node called smart meter runs an algorithm called Availability Based Energy Management algorithm. This algorithm learns about the previous usage patterns of the appliances, collects real time power consumption of appliances from WEEMAN to generate efficient energy load patterns. The highpoint of the algorithm is that it gives an option for the user to set their monthly current bill and pro-actively control the operation of all the appliances according to the amount. We have developed a hardware test bed consisting of WEEMAN connected to some selected appliances and a smart meter to control every WEEMAN.

Cardiovascular diseases (CVD) are one of the leading causes of death in rural India. Every year more than 3 million Indian citizens die from CVD [1]. The proposed Wearable Wireless Cardiac Monitoring (WiCard) system, aims to bring home state-of-the-art health care for people living in rural Indian villages, where thousands of death occur each year due to lack of experts and facilities. The architecture involves remote monitoring of the ECG by specialized health professionals via a heterogeneous wireless network. This paper discusses the development of a six lead custom hardware for transmitting data to a Smartphone or a compatible device via a Bluetooth. The data received by the mobile devices will be further processed and transmitted to a central repository located in a specialized hospital. The main disadvantage of wearable cardiac monitoring system is the introduction of Motion Induced Artifacts (MIA), which could mimic a cardiac event. A context aware architecture is proposed here to relate physical activity and physiological signals of the user, with the help of accelerometer sensors. The portion of ECG where the MIA has detected will be tagged and sent to the central repository. Classifications of physical movements are done using statistics based classifiers, which are computationally low cost. The results show that the developed algorithm is capable of classifying the user activity with an accuracy of 94%. The developed hardware achieved a power reduction of 10 %.

Dr. Maneesha V. Ramesh, Anu, T. A., and Thirugnanam, H., “An intelligent decision support system for enhancing an m-health application”, in IFIP International Conference on Wireless and Optical Communications Networks, WOCN, Indore, MP, 2012.[Abstract]


In most of the developing countries, the rural population is denied of the efficient and effective health care facilities. This increases the mortality of people in very young age due to several unknown and untreated diseases. This situation can be improved by adopting the usage of wearable sensors that are capable of continuously monitoring the patients and issue warnings to specialized experienced doctors in hospitals or to the care takers. This approach will bring in better healthcare facility to the people living in the rural world or to the people who are unnecessarily staying in the hospitals just for the purpose of monitoring. This can also help those people who do not want to stay in hospitals. However the efficiency of such a system will depend on the capability of the decision support system integrated with it. Hence this research work aims at the development of a decision support system architecture that can support data collection and processing from multiple wearable wireless sensors. The real-time data received from multiple wearable sensors will be analyzed for a variety of diseases. The results will be stored and send to the required persons via SMS. As an initial step towards the development of decision support system, a prototype system is developed that can be used for the monitoring of cardiac disease such as Ischemia, Myocardial Infarction, Cardiomyopathy, Hypokalaemia, Hyperkalaemia, First degree AV Block and Wolff Parkinson White Syndrome. This work has also developed a new risk based scheduling algorithm to handle the data processing so that the patients with the highest risk are processed first. The work also includes the implementation of several techniques such as decision trees for taking better decisions and for proper classification of diseases. © 2012 IEEE.

There is a lack of timely access to necessary healthcare in remote areas, especially in India. This paper addresses the availability of quality healthcare, by introducing wireless technology to monitor patients, in remote areas. A reliable system to continuously monitor the patients in the remote areas has been developed, this software suite consists of two mobile software platforms. The first mobile software platform uses wearable wireless sensors to collect a Patient's ECG and Blood Pressure based on the patient's health condition. This sensed data is transmitted to the Patient's mobile phone where the first level of analysis is performed and an emergency warning may be indicated. If the patient's parameters are at a certain level a message is sent immediately to the Health Professional's mobile phone. The health data is also transmitted it to a central server for storage and further processing. This database can be of great value to health researchers. The second mobile software platform enables health professionals to view patient's health reports on their mobile phones from the central database. The health professional can also assign the risk levels of each patient, from the health professional's mobile phone. Both platforms communicate with the central database using a web server. This research also considers power optimization in the patient's mobile.

Ensuring the security of wireless sensor networks (WSNs) is vital for monitoring real-time systems. One of the major security flaws experienced by WSNs is denial of service (DoS) which can even lead to the breakdown of the complete system or to wrong decisions being made by the system that can cause adverse results. This research work focuses on two techniques for detecting a DoS attack at a medium access control (MAC) layer. Our research compares and evaluates the performance of two major machine learning techniques: neural network (NN) and support vector machine (SVM). Vanderbilt Prowler is used for simulating the scenarios. In the simulations, normalized critical parameters and their corresponding probabilities of DoS attack are computed in 50 trial runs. These normalized critical parameters and their corresponding probabilities of DoS attack are used as training inputs in NN and SVM approaches. The simulation results clearly show that SVM provides better accuracy compared to NN, 97% accuracy by SVM and 91% accuracy by NN. The simulation also shows that SVM takes much less time to detect and determine the probability of a DoS attack, 0.25 seconds by SVM and 0.75 seconds by NN. All these results clearly show that SVM performs better than NN when used for detecting the probability of DoS attack in WSNs. © 2012 IEEE.

Disasters aroused due to dynamic movement of large, uncontrollable crowds are ever increasing. The inherent real-time dynamics of crowd need to be tightly monitored and alerted to avoid such disasters. Most of the existing crowd monitoring systems is difficult to deploy, maintain, and dependent on single component failure. This research work proposes novel network architecture based on the key technologies of wireless sensor network and mobile computing for the effective prediction of causes of crowd disaster particularly stampedes in the crowd and thereby alerting the crowd controlling station to take appropriate actions in time. In the current implemented version of the proposed architecture, the smart phones act as wireless sensor nodes to estimate the probability of occurrence of stampede using data fusion and analysis of embedded sensors such as tri-axial accelerometers, gyroscopes, GPS, light sensors etc. The implementation of the proposed architecture in smart phones provides light weight, easy to deploy, context aware wireless services for effective crowd disaster mitigation.

B., and Hemalatha, T., “Wireless sensor network security: Real-time detection and prevention of attacks”, in Proceedings - 4th International Conference on Computational Intelligence and Communication Networks, CICN 2012, Mathura, Uttar Pradesh, 2012, pp. 783-787.[Abstract]


Security is a critical issue in many real-world applications of wireless sensor networks (WSNs). This research focuses on implementing security mechanisms, against two specific types of attack that occur in a network of MICAz motes. These are 'denial-of-service' (DoS) attacks where unnecessary packets are sent causing services to appear unavailable and thus these services are denied to the legitimate sensor nodes, and 'passive information gathering' attacks where an adversary tries to obtain the confidential information stored in wireless sensor nodes. A machine learning technique named neural network (NN) is used to detect DoS attack conducted by an adversary. We compare and evaluate NN with our new method. The results clearly show an improved performance for our new proposed symmetric-key algorithm compared to NN. Lower encryption computational energy cost (8 μJ vs 16 μJ), lower memory requirements (8896 bytes of ROM and 434 bytes of RAM vs 15848 bytes of ROM and 763 bytes of RAM), and less execution time (0.164835 ms vs 0.6208791 ms) show the significant advantages of using symmetric-key algorithm instead of NN for detecting DoS attack. © 2012 IEEE.

K., “Low Power Intelligent Wearable Cardiac Sensor Using Discrete Wavelet Compression”, in Proceedings of the 2012 International Conference on Advances in Mobile Networks, Communication and Its Applications, MNCApps 2012, Bangalore, Karnataka, 2012, pp. 107-110.[Abstract]


Claiming 17.1 million lives a year, cardiovascular diseases are one of the major causes of death in the world especially in rural India. Conventional ECG monitoring instruments are quite bulky and if we are able to miniaturize them, then they can be used to collect data in scenarios that were not possible with the traditional systems. The system proposed here describes a low cost, low power wearable wireless sensor which can be used for issuing early warnings of cardiac disease to doctors, who are mostly mobile or who are away from the patient's location. The knowledge of early symptoms of a cardiac disease will provide an opportunity for the doctor to deliver real-time instructions to a relative/care taker for giving urgent medical care to the patient. Power optimisation has been achieved by using wavelet based compression technique (DWT) and also different modes of operation based on the risk factor of the patient. An algorithm based on discrete wavelet compression for power optimisation is developed and it is simulated in MATLAB. The results obtained shows that this technique achieves a power reduction of 22%. The proposed system can be used to deliver better healthcare to rural India, where availability of experienced doctors is almost scarce compared to urban India. © 2012 IEEE.

Wireless Sensor Networks (WSNs) consist of distributed autonomous devices which sense the environmental or physical conditions cooperatively and pass the information through the network to a base station. Sensor Localization is a fundamental challenge in WSN. Location information of the node is critically important to detect an event or to route the packet via the network. In this paper localization is modeled as a multi dimensional optimization problem. This problem is solved using bio inspired algorithms, because of their quick convergence to quality solutions. Distributive localization is addressed using Particle Swarm Optimization (PSO) and Comprehensive Learning Particle Swarm Optimization (CLPSO). The performances of both algorithms are studied. The accuracy of both algorithms is analyzed using parameters such as number of nodes localized, computational time and localization error. Comparison of both the results is presented. A simulation was conducted for 100 target nodes and 20 beacon nodes, which resulted in CLPSO being 80.478% accurate, and PSO 61.48% accurate. The simulation results show that the PSO based localization is faster and CLPSO is more accurate.

Rajesh Kannan Megalingam, Kaimal, D. M., and Dr. Maneesha V. Ramesh, “Efficient Patient Monitoring for Multiple Patients Using WSN”, in Proceedings of the 2012 International Conference on Advances in Mobile Networks, Communication and Its Applications, MNCApps 2012, Bangalore, Karnataka, 2012, pp. 87-90.[Abstract]


Real motivation of this research work is to develop an efficient system that can monitor multiple patients' health parameters simultaneously and can effectively deliver the data to a patient monitoring system where it is stored permanently. Current traditional health monitoring is accomplished by individual PCs attached to each patient's bed. The multiple parameters that are monitored are blood pressure, temperature, ECG, and EEG. Our research investigates the potential of WSN to reliably, wirelessly collect, send and process these multiple parameters of multiple patients simultaneously, in real-time. This research succeeds in transforming the traditional individual patient monitoring apparatus and its requirements into an apparatus that is capable of reliably monitoring the multiple parameters of up to six patients simultaneously, in real-time. Managing interference and ensuring the accurate delivery of the information to the monitoring system using the most effective wireless communication technique are the challenges taken in to consideration. This is achieved by identifying each patient's monitored parameter using a unique ID and employing a time scheduling scheme during data transmission. The system also alerts the doctor/nurse of some measured value cross threshold limits. A real time data storage mechanism employed here helps to look further into the recorded data by the doctor. This contribution succeeds in indicating where there could be huge savings in power consumption and cost for hospitals. Currently employed systems use a one patient monitoring system per patient which is expensive, whereas this system uses the same resources to monitor up to six patients, with more comfort to the patients and more convenience for the healthcare professionals. © 2012 IEEE.

Mobile ad hoc networks [MANET] are typically characterized by high mobility and frequent link failures that result in low throughput and high end-to-end delay. Present approaches to multipath routing make use of pre-computed routes determined during route discovery. All the paths are maintained by means of periodic update packets uncast along each path. In existing method best path is determined and maintained only with signal strength of disjoint paths. Signal strength between nodes is only the mobility prediction factor, which does not address the durability and stability of paths. Residual energy of nodes determines stability of path contains those nodes. Also does not consider the consistency of node through the previous behaves. This paper provides a design and a simulation frame work for measuring a Decision Value metric for mobility prediction of each alternate paths in MANET. Here a Periodic update packets measure Decision Value metric [DVM] and route maintenance is possible by means of the Signal strength between nodes, Residual energy and Consistency of each hop along the alternate paths, helps protocol to select the best scalable paths.

Most large-scale disasters are characterized by breakdown of essential communication systems. The failure of telecommunication system reduces the pace of emergency response and relief efforts. The paper is confined mainly on how communication can be carried even when a cellular network is down. The proposed system designs a participatory system for emergency communication. The existing participatory sensing systems have not addressed the issues arising when an area is hit with a disaster. By creating mobile ad hoc network of smart phones, it would be possible to allow messages requesting help to pass between phones until they are intercepted by a node which can directly connect to the cellular network or internet. An algorithm for routing the message in such a network is presented. It also showcases an android application called Android app for Emergency Communication (AEC) which would perform this task. © 2012 IEEE.

Wireless sensor network (WSN) refers to a group of spatially dispersed and dedicated sensors for monitoring and recording the physical conditions of the environment and organizing the collected data at a central location. Sensor Localization is a fundamental challenge in WSN. In this paper localization is modeled as a multi dimensional optimization problem. A comparison study of energy of processing and transmission in a wireless node is done, main inference made is that transmission process consumes more than processing. An energy efficient distributed localization technique is proposed.

This research is concerned with the design of Tree WSNs. This research proves that configuration plays a vital role in energy optimisation, node failure and network lifetime when designing a Tree WSN. We compare a Progressive Two Level Tree WSN with a Balanced Two Level Tree WSN. Our simulation results prove that a Progressive configuration has two advantages, over a Balanced configuration, which are less computations required to complete each process and more tolerance of node failures. These Progressive configuration advantages both lead to more energy efficiency compared to a Balanced configuration. Therefore, the lifetime of a Progressive Two Level Tree WSN is longer than that of a Balanced Two Level Tree WSN. © 2012 ACM.

When a disaster occurs, activities like search, rescue, recovery, and cleanup are carried out by emergency responders. This paper proposes a new framework for supporting the safety and health of emergency responders by locating their position and monitoring their vital signs using a Wireless Wearable Device. As an initial step towards the development of a wireless wearable tracking and monitoring system for emergency responders, this system uses an iterative localization based scheme, which provides the exact position of each emergency responder, and monitors their vital signs like skin temperature and pulse rate. Any change in the vital signs can be easily sensed and tracked, and could be used to provide warnings when critical events are detected. The system could be used to send early warning alerts and for communication between emergency responders. © 2012 ACM.

Wireless Sensor Networks are deployed in almost all areas as they are one of the efficient solutions for monitoring, detecting and providing early warnings. Energy minimization being one of the main challenges in WSNs, we present four different topology control algorithms which will compute the aggregated data in a distributed way, addressing this issue. Each algorithm optimizes power to different levels, by reducing the number of computations and transmissions. The discussed methods include two level and multi levels of balanced and progressive network and its analysis of energy savings. Among the four networks, multi-level progressive is found to be better for small number of sensor nodes (N<500), at the same time, multi-level balanced proved its efficiency when the number of sensors are large. The comparisons of four networks are discussed for atmost 4000 sensor nodes in a WSN. © 2012 IEEE.

This paper presents a novel methodology for optimal placement of Distributed Generation (DG) in an Optimal Power Flow (OPF) based wholesale electricity market. DG is placed in real time wholesale electricity market. The problem of optimal placement including size is formulated for two different objectives, namely, fuel cost reduction and to provide voltage stability at distribution level. DG reduces the cost of electricity to the costumer, relieve network congestion and provide environmental friendly energy close to load centers. The candidate locations for DG placement are identified on the basis of locational marginal price (LMP). OPF is widely used for both the operation and planning of a power system. The key feature of standardization of restructured power market like Standard Market Design (SMD) is the LMP scheme. OPF problem by placing DG in Deregulated Environment is solved using Genetic Algorithm (GA). The proposed methodology is tested with IEEE 30 bus test system.

Illicit and spurious alcohol consumption is leading to numerous deaths in rural India. The aim of this paper is to reduce the death due to the consumption of spurious alcohol by reducing the production of spurious alcohol. A Vehicular Ad- Hoc Sensor Network, MovingNet, is used to detect the production of spurious alcohol. Multiple sensors capable to detect the presence of methanol content or diazepam in a wide geographical area, is incorporated on the available public transport system that traverse through the rural areas of India, where high rate of spurious alcohol production is observed. The data received from the wireless sensors will be transmitted using the delay tolerant, public transport vehicular ad-hoc network, and analyzed at the central data management center. The results of the data analysis will provide the details of geographic information, the amount of presence of methanol content or diazepam, and the warning degree. This will be sent to the excise department which will help them to locate the position and stop the production of spurious alcohol. Thus the implementation of MovingNet will reduce the production of spurious alcohol and contributes the reduction in hazards due to the consumption of spurious alcohol. MovingNet is a cost effective solution since it uses a very few sensors and the available public transport system for data collection and transmission.

This paper proposes the design of a system that enables the severely disabled to communicate using their EOG, EMG and EEG signals. The typical approach is to modify the end devices to interpret these signals and to function accordingly [2-5]. But our system proposes an Interpreter System within which these signals are decoded and interfaced with the existing devices. The advantage is that the end devices need not be changed to suit the user, because the logic required for interpretation is within the Interpreter System. Therefore it acts as an interface through which the user can control multiple devices at the same time. Acquisition systems can capture and process EOG, EMG and EEG signals and transmit them to the Interpreter System via the Bluetooth Low Energy module. A communication language using EOG works in combination with EEG and EMG to enable communication. This language will help the users to interface with multiple devices with a limited number of symbols. © 2011 IEEE.

This paper describes a system that performs collaborative real-time sensing and monitoring of a disaster-hit area, using multiple Wireless Integrated Flying Robots (WiFR). These multiple WiFRs are designed to sense different environmental parameters; record images of the disaster hit area, and transmit these images to the command and control station (CCS). Each WiFR in the system has the capability to monitor unique regions, locate its position in real-time, and navigate to other regions according to real-time commands from the CCS. WiFRs are also integrated with collaborative sensing, processing, analyzing, and communication techniques. The efficient working of this multiple WiFR system requires the determination of the location of each of WiFR, the optimum number of WiFRs required for monitoring the entire disaster area, the paths with which minimum data packet loss and delay can be achieved, etc. Decision-making is dependent on various environmental propagation effects. During adverse environmental conditions, the WiFRs will use collaborative sensing as well as processing and analyzing techniques to determine the adaptable routes, thus avoiding the effects of wireless propagation and minimizing delay. Considering the capabilities of multiple WiFRs, this paper proposes an optimal positioning strategy of WiFRs that will effectively minimize the communication delay with respect to the dynamic propagation effects. An effective approach is also developed for determining the optimal density of WiFRs, to achieve guaranteed degrees of coverage. These results will provide important aspects necessary for effective disaster management. © 2011 IEEE.

Increased stress level in working environments, reduced sleep, variation in sleep pattern and time due to the adaptation of global time zone in working environments, increase in alcohol consumption, larger distance travel using high power automobiles, etc., contributes to increased level of driver drowsiness and fatigue. In the past decade, steep increase in accidents and loss of life was experienced mainly due to the increase in the driver drowsiness and fatigue. This research work aims in developing an intelligent wireless sensor network to monitor, and detect driver drowsiness in real-time. This real-time system consists of multiple non-obstructive sensors which continuously monitor the driver's physiological parameters and disseminate the first level alarm to the driver and the passengers. The second level alarm will be disseminated, along with the vehicle identification number and the real-time location coordinates of the driver, to the nearby police station or the rescue teams using the available wireless ah-hoc network, if the driver's state does not change even after the first level alarm. This research work contributed to the design and development of system architecture for real-time monitoring and detection of driver drowsiness. This work also integrated effective real-time sensor fusion techniques for monitoring the heart rate collected from the driver. One of the novel ideas in this research work is the development of multiple sensors embedded in the steering wheel capable to measure the heart rate and dynamically alert the driver or the rescue team about the driver drowsiness, to avert accidents. © 2011 IEEE.

After a large-scale disaster in an area, the existing communication systems may not be available either due to physical damage or system overload. The loss of the communication systems and information networks makes the rescue and relief operation extremely difficult. The proposed system designs a heterogeneous network for emergency communication. The proposed system uses communication equipment such as smart phones with Wi-Fi and GSM capabilities, and laptops with Wi-Fi. Soon after a disaster happens, it is proposed that Access Points (AP) can be deployed in the disaster area. As emergency vehicles generally already contain a base station they can be used as the APs. The system uses satellite communication to carry the data outside the disaster area. If cellular coverage of an area is lost, i.e. in a disaster, this system can move communications to an available network ensuring continual communication without disruption. © 2011 IEEE.

Dr. Maneesha V. Ramesh and Nisha, M. S., “Design of Optimization Algorithm for WLAN AP Selection during Emergency Situations”, in 2011 IEEE 3rd International Conference on Communication Software and Networks, ICCSN 2011, Xi'an, 2011, pp. 340-344.[Abstract]


WLAN is now widely used for emergency purposes because of its fast deployment capability. Efficient and intelligent arrangement and selection of access points (AP) are very crucial in emergency situations. Coverage and capacity are two central problems faced when APs are placed in a disaster scene. The paper proposes a power efficient algorithm for AP selection in emergency situations. The current AP selection algorithm only considers received signal strength, and this algorithm arise problems like overloading in APs, congestion and power wastage in networks. But the proposed Dynamic Load Balancing Fairness Algorithm (DLBFA) overcomes all these problems by using a new selection score, obtained by optimizing channel throughput and voice quality. Apart of this score the number of nodes connected to an AP and RSSI are also considered. The main advantage of DLBA is that it can work on both data and voice applications. © 2011 IEEE.

Recent years have shown an alarmous increase in rain fall induced landslides. This has facilitated the need for having a monitoring system to predict the landslides which could eventually reduce the loss of human life. We have developed and deployed a Wireless Sensor Network to monitor rainfall induced landslide, in Munnar, South India. A successful landslide warning was issued in June 2009 using this system. The system is being enhanced by incorporating a Wireless Geophone Network to locate the initiation of landslide. The paper discusses an algorithm that was developed to analyze the geophone data and automatically detect the landslide signal. A novel method to localize the landslide initiation point is detailed. The algorithm is based on the time delay inherent in the transmission of waves through the surface of the earth. The approach detailed here does not require additional energy since the geophones are self excitatory. The error rate of the approach is much less when compared to the other localization methods like RSSI. The proposed algorithm is being tested and validated, in the landslide laboratory set up at our university. © 2011 IEEE.

Nowadays, almost all the countries are facing threats from terrorists and intruders from their border areas, challenging the internal security of the country in those areas. So many civilian and military applications require locating an intruder in a secured area. Target tracking, data processing and analysis play a major role in this type of applications. The proposed system is to develop a centralized computer application that needs to identify moving objects in a specific area using sensors. The system will be basically designed to detect human intruders. The objective is to design and implement an object tracking system using a wireless sensor network. This application is able to detect and track objects, and report direction and speed of the intruder to a central base station. The human intruder is detected using a passive infrared (PIR) sensor. The sensor is connected to a MICAz sensor node. The PIR sensor is able to detect the humans and provide information about the direction of the movement. The gathered information from the sensor network is to be given to the base station for processing. The proposed system provides an environment for easy deployment and which does not require any existing infrastructure or constant monitoring by humans. © 2010 IEEE.

Electricity losses in India during transmission and distribution are extremely high and vary between 30 to 45%. Wireless network based architecture is proposed in this paper, for monitoring and optimizing the electric transmission and distribution system in India. The system consists of multiple smart wireless transformer sensor node, smart controlling station, smart transmission line sensor node, and smart wireless consumer sensor node. The proposed software module also incorporates different data aggregation algorithms needed for the different pathways of the electricity distribution system. This design incorporates effective solutions for multiple problems faced by India's electricity distribution system such as varying voltage levels experienced due to the varying electrical consumption, power theft, manual billing system, and transmission line fault. The proposed architecture is designed for single phase electricity distribution system, and this design can be implemented for three phase system of electricity distribution with minor modifications. The implementation of this system will save large amount of electricity, and thereby electricity will be available for more number of consumers than earlier, in a highly populated country such as India. The proposed smart grid architecture developed for Indian scenario, delivers continuous real-time monitoring of energy utilization, efficient energy consumption, minimum energy loss, power theft detection, line fault detection, and automated billing. © 2010 IEEE.

The main purpose of this research work is to develop a wireless sensor network system that can continuously monitor and detect cardiovascular disease experienced in patients at remote areas. A wearable wireless sensor system (WWSS) is designed to continuously capture and transmit the ECG signals to the patient's mobile phone. The fastest alert will be issued to doctors, relatives, and hospitals, using the proposed data processing algorithm implemented in the patients mobile phone. The complete data from WWSS will also be transmitted to a central station, which provides a service to the doctor to view his patient's record and provide his prescription remotely, on his request. A heterogeneous wireless network design is also proposed for the continuous transmission from WWSS to a Central Data Center (CDC). The proposed system is integrated with a dynamic data collection algorithm that collects the ECG signals at regular intervals, according to the health risk perceived in each patient. Employment of this system will contribute in reducing heart diseases, leading to death of a patient, and also act as an effective health care service to patients in rural area. This continuous monitoring system will provide effective, efficient, and fast health care service to patients at risk, even if the doctor, relatives are not near the patient and also during the non availability of the cellular network. © 2010 IEEE.

Dr. Maneesha V. Ramesh and Sangeeth, K., “Lightweight Management Framework for a Heterogeneous Wireless Network for Landslide Detection”, in the International conference on Wireless & Mobile Networks, WiMoN (in lecture series of Springer), 2010.[Abstract]


Wireless Sensor Networks (WSN) are networks of low cost nodes with minimal power consumption, processing capabilities and maintenance, that can be used for wide area environmental monitoring. This paper discusses the main innovations, challenges, solutions and deployment experiences in designing a Lightweight Management Framework (LMF) for a real-time, 24/7 operational, heterogeneous network. The network must reliably deliver data continuously from a set of deep earth probe sensors in a remote hilly rainforest area to a data management, analysis, and visualization center at the University campus hundreds of miles away. This framework provides the ability to incorporate different heterogeneous networks such as 802.15.4, 802.11b/g, VSAT, GPRS, GSM, Internet and also proprietary wireless sensor network and hardware architectures. It also handles various network failures, data corruption, packet loss, and congestion problems. The data is analyzed to determine the factor of safety of the landslide prone area using landslide simulation software, stream data in real-time to the internet, and give automatic warnings. The architecture has been implemented in a real-time wireless sensor network deployed in the Western Ghats of Kerala, India to detect landslides. The architecture is operational in the deployment site since February 2008 and was used to issue landslide warnings during the July 2009 monsoon.

Dr. Maneesha V. Ramesh, Vasudevan, N., and Freeman, J., “Real Time Landslide Monitoring via Wireless Sensor Network”, in EGU General Assembly Conference Abstracts, 2009.[Abstract]


Rainfall induced landslides are a common phenomena in the Western Ghat region of Southern India and result in numerous fatalities and damage to property. In order to collect the most relevant and useful data, at the&nbsp;time&nbsp;it is most needed, a&nbsp;wireless&nbsp;sensor&nbsp;network&nbsp;is being used for&nbsp;landslide&nbsp;monitoring. The advantage it gives to&nbsp;landslide&nbsp;monitoringis that it is an inexpensive and reliable way to communicate rapidly over a long distance and inhospitable terrains, collect data in&nbsp;real-time, and alter the data collection rate remotely to suit current environmental conditions. We have implemented a&nbsp;real&nbsp;time&nbsp;landslide&nbsp;monitoring&nbsp;system over a seven acre active complex&nbsp;landslide&nbsp;site. An array of geological sensors (piezometers, tiltmeters, strain gauges, rain gauges, dielectric moisture sensors, geophones) has already been deployed and the data is being automatically collected and forwarded via the&nbsp;wireless&nbsp;sensor&nbsp;network. The geotechnical data is then transferred over 300 km via a satellite link to a remote&nbsp;monitoring&nbsp;station for further analysis. This will give us a better understanding of landslides in this region and prevent the loss of human life.

The installation or deployment of a wireless sensor network (WSN) in a real world application is prone to innumerable failures such as software or hardware malfunctioning, environmental hazards, radio interference, battery exhaustion, etc. In a safety critical application such as landslide prediction, fault tolerant approaches have to be followed to ensure the availability of sensor data at the analysis station during a critical situation. We propose a fault tolerant and energy efficient clustering approach which organizes the whole network into smaller cluster and subcluster groups enabling a considerable reduction of communication and processing overhead. Subcluster formation also gives the possibility to skillfully deal with sensor nodes, node leader, and cluster head failures. We also propose a fault tolerant approach that uses a matrix based error approximation method for providing the approximate sensor data of the failed node. The approximate code prediction takes into consideration various geological aspects of the problem.

In Indian coastal zone, real-time tracking of fishing vessels is nonexisting. This leads to numerous challenges in search and rescue operation, communicating emergency messages, etc. A quick solution for this is to install GPS devices, which is costly. In our research work, we designed and developed a low-cost hybrid solution with minimum number of location aware nodes. Real-time relative location information of mobile sensor nodes was developed by integrating mobility management, virtual coordinate system (VCS), and topology preserving map (TPM). The architecture is implemented in MATLAB and is tested with a rectangular network scenario with up to five mobile nodes and is able to track the relative location trace of mobile nodes at a particular interval of time. The effect of various simulation parameters such as communication range, node placement, number of mobile nodes, and sampling rate selection in tracking the mobile nodes with our system is also performed. © Springer India 2016.

Mobile devices are becoming the preferred choice for internet access as they are getting increasingly powerful and affordable. But because of lack of ubiquitous high bandwidth wireless internet, many mobile applications suffer from performance and reliability issues while accessing data from the servers. While many of the applications use caching mechanism to store data locally on mobile device to improve data access performance, they are not thoroughly focusing on related areas such as two-way data synchronization, fault tolerance and recovery, offline mode support and real-time update support. And hence even many reputed applications show inconsistent and out-of-date data; especially during network and battery outages. In this paper we propose usage of Replication process, Pending data process, targeted data update broadcasts to solve the above issues in the software architecture of Smart-Home project. © Springer Science+Business Media Singapore 2016.

Wireless sensor networks (WSN) are also being actively researched and learned as part of graduate and undergraduate technical disciplines as they are being applied in variety of fields such as landslide detection, smart home monitoring etc. It is essential for the students to learn the WSN concepts through experimentation. But it needs a lot of time, hardware resources and technical expertise to design, program, setup, and maintain these experiments. A shared remote triggered (RT) WSN test-bed which can be accessed, controlled, monitored through internet would be of great help for many students to learn these concepts quickly without any setup at their end. Our RT WSN test-bed consists of 11 experiments, each deigned to explore a particular WSN concept. Each experiment consisting of a WSN setup, a web interface for user input and results, and middleware layer to communicate between web and WSN [1, 2, and 3]. In this paper we present the architecture of our flexible and extensible middleware framework; a single code base supporting all the experiments which can be easily extended for any other WSN experiment just by configuring. We also illustrate the success of our system through the analysis of various usage statistics. © Springer International Publishing AG 2016.

In a smart distribution power grid, cost efficient and reliable communication architecture plays a crucial role in achieving complete functionality. There are different sets of Quality of Services (QoS) requirements for different data packets transmitting inside the microgrid (a regionally limited smart distribution grid), making it challenging to derive optimal communication architecture. The objective of this research work is to determine the optimal communication technologies for each data packet based on its QoS requirement. In this paper, we have proposed an architecture for a smart distribution power grid with Cyber Physical System enabled microgrids, which accommodate almost all functional requirements of a smart distribution power grid. For easy transition towards optimal communication architecture, we have presented a six-tier communication topology, which is derived from the architecture for a smart distribution power grid. The optimization formulations for each packet structure presented in this paper minimize the overall cost and consider the QoS requirements for each packet. Based on the simulation results, we have made recommendations for optimal communication technologies for each packet and thereby developed a heterogeneous communication architecture for a microgrid.

Fishermen at sea lack proper localization and tracking systems leading to increased loss of life at sea due to disasters, engine failure, and collision with ships. To reduce the impact of such scenarios we need an efficient localization and tracking algorithm for approximate localization of fishing vessels in a spatio – temporal domain. In this work, we have analyzed few existing algorithms for localization of mobile sensor nodes and based on these results, an Enhanced Chord Based Localization Algorithm (ECLA) has been designed and developed. The proposed algorithm is implemented and extensively tested on the basis of different performance parameters such as mobility, localization accuracy, execution time etc. The experimental results clearly show that the proposed algorithm has better localization accuracy compared to the existing localization algorithms. The accuracy of the proposed ECLA algorithm is 26.5% better than that of Monte Carlo Boxed (MCB) localization scheme.

In a maritime environment, affordable long range communication network for fishing vessels are highly necessary for safety at sea and to communicate to shore and back to the fishing vessels. The existing communication architecture faces major challenges in achieving seamless connectivity due to the mobility of fishing vessels, lack of backbone infrastructure, propagation effects, and fault tolerance. In this work, we explored the capability of Delay Tolerant Networks (DTN) for providing better connectivity under the above mentioned parameters. Existing DTN protocols such as Epidemic, Spray and Wait and MaxProp protocols were studied and analyzed for maritime scenario. These protocols were simulated in Opportunistic Networking Environment (ONE) simulator and analyzed with respect to node density, node mobility, and intermittent connectivity. The results show that Epidemic protocol has moderate average latency, whereas Spray and Wait protocol and MaxProp has better data delivery rate with lesser average latency.

Our research works focuses on the design and implementation of a novel ubiquitous multi context-aware mobile phone sensing network for mitigation of crowd disasters using machine-to-machine (M2M) communications. A mobile sensor network system integrated with wireless multimedia sensor networks (WMSNs) was designed for effective prediction of a stampede during crowd disasters. This proposed sensor network consists of mobile devices that are used as crowd monitoring participant nodes that employ light sensors, accelerometers, as well as audio and video sensors to collect the relevant data. Real-time crowd dynamics modeling and real-time activity modeling have been achieved by implementing the algorithms developed for Context Acquisition and multi-context fusion. Dynamic crowd monitoring was achieved by implementing the context based region identification and grouping of participants, distributed crowd behavior estimation, and stampede prediction based on distributed consensus. The implementation of the proposed architecture in Android smartphone provides light-weight, easy to deploy, context aware wireless services for effective crowd disaster mitigation and generation of an in time alert to take measures to avoid the occurrence of a stampede. The system has been tested and illustrated within a group of people for stampede prediction by using empirically collected data.© 2013 Elsevier B.V.

While there is large body of work examining efficacy of Virtual Labs in engineering education, studies to date have lacked modeling Blended Labs (BL) - mix of Virtual Labs (VL) and Physical Labs (PL) for science experimentation at the university engineering level. Using Rogers theory of perceived attributes, this paper provides a research framework that identifies the attributes for BL adoption in a social group comprising of (N=246) potential adopter undergraduate engineering students. Using Bass model the study also accounts for the interinfluence of related group of potential adopter faculties who are likely to exert positive influence on students. The results revealed that acceptance of BL as an innovation and its learning outcomes are strongly associated with innovation attributes like Relative Advantage, Compatibility, Ease of Use, Department and Faculty support. Learning outcomes are very positive under BL when compared to PL, though within BL, ordering of PL and VL was not significant. For certain innovation attributes gender differences were significant. Overall students expressed much more positive attitude to adopt BL model for learning than using only PL. © Institute for Computer Sciences, Social Informatics and Telecommunications Engineering 2014.

Within the context of Roger's Diffusion of Innovation theory we propose a pedagogical framework for attributes that can significantly affect student adoption of collaborative learning environment like multi-user, multi-touch tabletop. We investigated the learning outcomes of secondary school students in India collaboratively using OLabs on a tabletop (EG1 = 30) vs. individually using at desktops (EG2 = 92). We analyzed the nature of communication, touch and non-touch gesture actions, position around the tabletop, focus group interviews, and pre and post test scores. Using Bass model the study also accounts for the inter influence of related group of potential adopter teachers who are likely to exert positive influence on students. The results revealed that learning outcomes on tabletop are strongly associated with innovation attributes like Relative Advantage, Compatibility, Ease of Use, Perceived Enjoyment, Perceived usefulness and Teachers support. Overall students expressed much more positive attitude to adopt tabletop technology for learning vs. desktop. We find that the mean group performance gain is significant with collaboration using tabletop and significantly greater than the group using desktops. We also find that the group interactions with the tabletop area significant factor that contributes to the group's average performance gain. However, the total time spent in while using the tabletop is surprisingly not a significant factor in the performance gain. Our findings contribute to the design of new pedagogical models for science learning that maximizes the collaborative learning potential of tabletops. © 2014 Springer International Publishing Switzerland.

Our research works focuses on the design and implementation of a novel ubiquitous multi context-aware mobile phone sensing network for mitigation of crowd disasters using machine-to-machine (M2M) communications. A mobile sensor network system integrated with wireless multimedia sensor networks (WMSNs) was designed for effective prediction of a stampede during crowd disasters. This proposed sensor network consists of mobile devices that are used as crowd monitoring participant nodes that employ light sensors, accelerometers, as well as audio and video sensors to collect the relevant data. Real-time crowd dynamics modeling and real-time activity modeling have been achieved by implementing the algorithms developed for Context Acquisition and multi-context fusion. Dynamic crowd monitoring was achieved by implementing the context based region identification and grouping of participants, distributed crowd behavior estimation, and stampede prediction based on distributed consensus. The implementation of the proposed architecture in Android smartphone provides light-weight, easy to deploy, context aware wireless services for effective crowd disaster mitigation and generation of an in time alert to take measures to avoid the occurrence of a stampede. The system has been tested and illustrated within a group of people for stampede prediction by using empirically collected data. © 2013 Elsevier B.V. All rights reserved.

In this paper, we present a state-of-the-art wireless sensor network (WSN) of deep-earth probes (DEPs) that has been deployed to monitor an active landslide in the Western Ghats mountain range of South India. While India has one of the highest incidences of landslides and landslide-induced fatalities-primarily in the Himalayas of North India and in the Western Ghats of Central and South India-our study is perhaps the first comprehensive attempt to instrumentally detect landslides in the Western Ghats. Wireless networks have enabled us, since June 2009, to continuously monitor the deployment site in real time and from anywhere around the globe. There have been a few earlier landslide monitoring WSNs using accelerometers in Emilia Romagna Apennines, Italy; global navigation satellite system (GNSS) sensors to monitor the Hornbergl landslide, Austria; and vibrating wire stress sensors to monitor a slope in China. We improved upon these WSN systems by incorporating a variety of sensors-piezometers, dielectric moisture sensors, strain gauges, tiltmeters, a geophone, and a weather station-and installing some of these sensors as deep as 20 m below the ground surface. We present the salient aspects of the field deployment of DEPs: the selection of sensors and their incorporation in DEPs, the methodology we used in embedding these DEPs into the soil, and a few of the key aspects of the wireless sensor network. We also present a description of the deployment site and some of the results of geotechnical investigations carried out on borehole corings. Finally, we present the more interesting field data collected from the monitoring system during a rainy season in July and August 2009. © 2011 Springer-Verlag.

A worldwide increase in number of natural hazards is causing heavy loss of human life and infrastructure. An effective disaster management system is required to reduce the impacts of natural hazards on common life. The first hand responders play a major role in effective and efficient disaster management. Locating and tracking the first hand responders are necessary to organize and manage real-time delivery of medical and food supplies for disaster hit people. This requires effective communication and information processing between various groups of emergency responders in harsh and remote environments. Locating, tracking, and communicating with emergency responders can be achieved by devising a body sensor system for the emergency responders. In phase 1 of this research work, we have developed an enhanced trilateration algorithm for static and mobile wireless sensor nodes. This work discusses an algorithm and its implementation for localization of emergency responders in a disaster hit area. The indoor and outdoor experimentation results are also presented. © 2012 ICST Institute for Computer Science, Social Informatics and Telecommunications Engineering.

Illicit and spurious alcohol consumption is leading to numerous deaths in rural India. The aim of this paper is to reduce the death due to the consumption of spurious alcohol by reducing the production of spurious alcohol. A Vehicular Ad-Hoc Sensor Network, MovingNet, is used to detect the production of spurious alcohol. Multiple sensors capable to detect the presence of methanol content or diazepam in a wide geographical area, is incorporated on the available public transport system that traverse through the rural areas of India, where high rate of spurious alcohol production is observed. The data received from the wireless sensors will be transmitted using the delay tolerant, public transport vehicular ad-hoc network, and analyzed at the central data management center. The results of the data analysis will provide the details of geographic information, the amount of presence of methanol content or diazepam, and the warning degree. This will be sent to the excise department which will help them to locate the position and stop the production of spurious alcohol. Thus the implementation of MovingNet will reduce the production of spurious alcohol and contributes the reduction in hazards due to the consumption of spurious alcohol. MovingNet is a cost effective solution since it uses a very few sensors and the available public transport system for data collection and transmission. © 2012 ICST Institute for Computer Science, Social Informatics and Telecommunications Engineering.

In this paper we present a wireless wearable body area system for locating, tracking and monitoring emergency responders in harsh and remote environments. Tracking an emergency responder and monitoring their vital signs using various medical sensors is important in supporting the safety of the emergency responder. This work is the preliminary step towards the development of a collaborative real-time tracking and monitoring system for emergency responders. In this paper, we propose a design of a wrist worn wireless wearable body sensor device for localizing, tracking and monitoring an emergency responder. Any change in the physiological parameters like blood oxygen level, blood pressure and pulse rate of the emergency responder can be easily sensed and tracked, and could be used to provide a warning when a critical event is detected. This system uses an efficient iterative localization scheme for locating the emergency responder. The system could be used to send early warning alerts, route proper medical supplies to the area required, and for communication between the responders.

The Electrocardiogram (ECG) is a graphical recording of the electrical signals generated by the heart. The signals are generated when the cardiac muscles depolarize in response to electrical impulses generated by the pacemaker. In this work, we propose an efficient method to monitor and classify the ECG signals. The initial task carried out was to eliminate the noise, which involved extracting the required cardiac components by rejecting the background noise. The second task was to perform R peak detection, which was achieved by using the Windowed Short Time Fourier Transform (STFT). The Heart Rate Variability (HRV) was also found by calculating the difference between two simultaneous R-Peaks. The simulations were carried out in the MATLAB environment. The experiments were carried out using data from the MIT-BIH Database. This paper proposes an algorithm to monitor cardiac atrial fibrillation, which is an essential precursor to myocardial infarction.

Wireless Sensor Networks (WSN) are networks of low cost nodes with minimal power consumption, processing capabilities and maintenance, that can be used for wide area environmental monitoring. This paper discusses the main innovations, challenges, solutions and deployment experiences in designing a Lightweight Management Framework (LMF) for a real-time, 24/7 operational, heterogeneous network. The network must reliably deliver data continuously from a set of deep earth probe sensors in a remote hilly rainforest area to a data management, analysis, and visualization center at the University campus hundreds of miles away. This framework provides the ability to incorporate different heterogeneous networks such as 802.15.4, 802.11b/g, VSAT, GPRS, GSM, Internet and also proprietary wireless sensor network and hardware architectures. It also handles various network failures, data corruption, packet loss, and congestion problems. The data is analyzed to determine the factor of safety of the landslide prone area using landslide simulation software, stream data in real-time to the internet, and give automatic warnings. The architecture has been implemented in a real-time wireless sensor network deployed in the Western Ghats of Kerala, India to detect landslides. The architecture is operational in the deployment site since February 2008 and was used to issue landslide warnings during the July 2009 monsoon. © 2010 Springer-Verlag Berlin Heidelberg. More »»

An 'open access' generic high-performance liquid chromatography method was developed for different combination sets each containing specific cytochrome P450 probe substrate and the corresponding metabolite. Method development, optimization and validation were carried out with the following combinations: phenacetin + paracetamol + internal standard (IS, celecoxib), bufuralol + hydroxybufuralol + IS, testosterone + 6β-hydroxytestosterone + IS, chlorzoxazone + 6-hydroxychlorzoxazone + IS, coumarin + 7-hydroxycoumarin + IS, tolbutamide + hydroxytolbutamide + IS, and diazepam + desmethyldiazepam + IS. 2. The assay procedure involved a simple one-step liquid/liquid extraction followed by reverse phase chromatography (Inertsil ODS 3V column) employing a ternary gradient system and the eluate was monitored by a photodiode array/fluorescence detector. The standard curve for each compound, in the concentration range 0.1-10 μg ml-1, in various sets was linear (r2 &gt; 0.99) and absolute recoveries of all analytes were &gt; 90%. The lower limit of quantification was 0.1 μg ml-1. The intraday precision and accuracy in the measurements of quality control were &lt; 15% relative standard deviation and &lt; 15% deviation from nominal values, respectively. 3. Each combination set was tested with individual chemical inhibitors (furafylline, quinidine, ketoconazole, disulfiram, diethyldithiocarbamate, sulphaphenazole and tranylcypromine) and all analytes were well resolved. Overall, the assay is simple, uses conventional instrumentation and provides a scope to analyse all cytochrome P450 combination sets continuously. The application of the method in the cytochrome P450 liability screen of novel compounds is also presented.

Younas, Awan, I., Kryvinska, N., Strauss, C., and van Thanh, D. Cham: Springer International Publishing, 2016, pp. 283–294.[Abstract]


We present an intelligent data management framework that can facilitate development of highly scalable and mobile healthcare applications for remote monitoring of patients. This is achieved through the use of a global log data abstraction that leverages the storage and processing capabilities of the edge devices and the cloud in a seamless manner. In existing log based storage systems, data is read as fixed size chunks from the cloud to enhance performance. However, in healthcare applications, where the data access pattern of the end users differ widely, this approach leads to unnecessary storage and cost overheads. To overcome these, we propose dynamic log chunking. The experimental results, comparing existing fixed chunking against the H-Plane model, show 13 %–19 % savings in network bandwidth as well as cost while fetching the data from the cloud.

Ubiquitous Computing with Context Awareness is emerging as a significant technology which is capable of supporting a wide variety of real world applications such as health care, environmental monitoring, security, etc. Most of the existing Context aware frameworks developed are single-application oriented. The key focus of our research work is to bring in multiple application support using single context aware framework. The proposed Ubiquitous Multi-Context Model (UMM) contains a new module “Context Categorizer” for spanning multiple real world applications. The designed model support non redundant information capturing and appropriate data sharing among multiple applications, by utilizing the potentials of wireless sensor networks. The implementation of the proposed model considers two relevant applications, health care and crowd behavior estimation, which are gaining attention nowadays.
