Usage of drones has become very popular but its fullest potential can only be realized when collaborated with other customized sensors, subsystem performing functionalities like image processing, navigation control, robotic actuation. This project helps in utilizing drone technology in an effective way to solve different issues of society by proposing a CNN based image processing model which is effective for aerial surveillance with various smart autonomous modes. The paper also discusses the requirement for employing such faster, simpler, and effective working methods in aerial surveillance by streamlining, and enhancing its operations by overcoming the various challenges of aerial imaging utilizing pose estimation. Apart from detecting pedestrian activities by using pose estimation, it is even trained to classify gender, detect weapons, fire accidents, and sparkling of roadside electric wires. It can be installed on a drone by following technical details and working states provided in later sections of this paper using master-slave protocol or it can also function independently as a Smart CCTV camera when not setup on the drone. The prototype is implemented using Raspberry Pi, Arduino connected with PI-camera, GPS Neo 6m, HC-SR04 ultrasonic sensor and the model uses the Tensor flow and OpenCV. Later the model is tested for being controlled by specially designed LABVIEW GUI and then Python GUI is programmed for controlling modes and display purposes. The model discussed in this paper also intended to deliver enhanced general protection but seriously encompasses other dimensions of crime like VAW-Violence against women and SGBV- Sexual and Gender-based Violence.

M. Meghana, Kumar, N., and Giriraja C. V., “Performance Analysis of Virtual MIMO in Wireless Sensor Networks”, in 2019 IEEE International Conference on Electronics, Computing and Communication Technologies (CONECCT), Bangalore, India, 2019.[Abstract]


In this paper, we have investigated on virtual multiple-input-multiple-output (V-MIMO) in wireless sensor networks (WSNs) and carried out the performance analysis for this system. An energy consumption model is developed for a cooperative virtual MIMO WSN. For a given geographical area and number of nodes, we optimized the values of various performance parameters like, the number of cooperative nodes, number of cluster heads, communication range distance and so on, to ensure increased life time of sensor nodes. Simulation results are presented for different cases and scenarios. It is observed that V-MIMO WSN can be efficiently designed and optimized for the targeted applications.

To increase the energy and spectral efficiency in the field of communication, a new technique named Device to Device Communication (D2D) is proposed. This is very essential as there has been a massive growth in the number of connected devices now a days. D2D takes advantage of the physical proximity of communication devices and enables direct communications between them (i.e.) devices communicate with each other without the intermediate nodes. This proximity of devices helps in achieving extremely high bit rates, low delays, and low power consumption. Although there are many benefits of D2D, the implementation of it is very strenuous. There are a number of challenges need to be addressed before establishing a successful D2D connection. One among those is the clustering of devices. Clustering is the grouping of devices based on a particular criteria. In this paper, we first created nodes, found which devices are capable of forming a D2D link, divided them into clusters and then found the cluster head (CH) for each cluster. Finally we plotted graphs for throughput versus the threshold SNR and the distance between the links.

Surveillance of roads using Unmanned Aerial Vehicles (UAV's) is an upcoming technology which has advantages over existing automatic traffic control methods. Irrespective of the fact that the existing video analysis gives 85-90 percent accuracy, they have a few faults in calculating the exact count of vehicles. So, our project involves frame by frame analysis of videos for better results. The framework includes three steps which are detection of foreground, detection of blobs, dilation and counting of vehicles.

In this paper, a health care system is described for rural areas considering a small village using hybrid network i.e. which operates both in ADHOC and cellular region. In this system, a small village is considered in which sensors are attached to people, the whole area is divided into clusters. The sensors considered for this system can operate in both ADHOC and GSM region. In each cluster, a sensor is fixed as cluster head (CH) and continuous energy is supplied to it ensuring that it will be active all the time. All the sensors connected to the patients will work in ADHOC region and one sensor operates in GSM network acting as a gateway between all the CH's and the base station (BS). The information about the patient's condition will be sent to BS through gateway sensor only if there is an emergency. Even in case of gateway sensor failure any other sensor in the village which is able to communicate with all sensors can act as gateway by switching its operation to cellular network. The data is sent to BS using reactive ADHOC routing protocols. By simulation it has been shown that this system is good in terms of energy efficiency and throughput compared to a system in which the CH changes periodically

Dr. T. K. Ramesh and Giriraja C. V., “Wireless sensor network protocol for patient monitoring system”, in 2017 International Conference on Computer Communication and Informatics, ICCCI 2017, 2017.[Abstract]


In this paper, an efficient routing protocol for patient monitoring system in rural areas was proposed using wireless sensor network (WSN) so that the patients can be treated within less time. In this system, a village with GSM network is considered and the people in that village are continuously monitored using AMON sensor, an advanced medical monitoring and alert system. All the AMON's work in ADHOC region and one AMON in the village will work in GSM network acts as a gateway between the other sensors and BS. According to the patient's condition the information has to be sent to base station (BS). In this scenario, the routing of information is based on condition of the patient so on demand or reactive routing protocols are used. Different reactive routing protocols AODV, DSR are studied and modifications are done in them and compared to find the best protocol. Routing is done based on the efficient routing protocol and by simulation it is shown that the routing protocol is best in terms of throughput, end to end delay compared to other protocols.

Dr. T. K. Ramesh, Giriraja C. V., ,, ,, and M.H., I., “Efficient SCT Protocol for Post Disaster Communication”, in IOP Conference Series: Materials Science and Engineering, 2017, vol. 225.[Abstract]


Natural and catastrophic disasters can cause damage to the communication system, the damage may be complete or it may be partial. In such areas communication and exchange of information plays a very important role and become difficult to happen in such situations. So, the rescue systems should be installed in those areas for the rescue operations and to take important decisions about how to make a connection from there to the outside world. Wireless communication network architecture should be setup in disaster areas for the communication to happen and to gather information. Wireless ad-hoc network architecture is proposed in this paper with access nodes. These access nodes acts as hotspot for certain area in which they are set up such that the Wi-Fi capable devices get connected to them for communication to happen. If the mobile battery is drained in such situations wireless charging using microwave is shown in this paper. Performance analysis of the communication transport layer protocols is shown and Efficient SCTP (ESTP) algorithm is developed which shows better results in terms of cumulative packet loss. © Published under licence by IOP Publishing Ltd.

In this paper, an efficient multicast routing protocol was proposed for device to device (D2D) communication which helps in increasing the transmission power efficiency, quality of service (QoS) and also reduces the blocking probability and latency. In our algorithm, the packet transmission sequence is decided by the users need i.e. data demand. Base station (BS) selects one as the cluster head (CH) among the users in this method based on the power level. Cluster head changes for different transmissions and will be able to access all the users at that particular time. For a particular packet transmission BS decides one of the users who have received more number of requests as transmitter and that transmits packets to all the requested users. Routing is done according to our algorithm and by simulation we have shown that transmission power efficiency increases, blocking probability and latency decreases compared with [1] and [2].

In this work, an efficient channel utilization scheme based on the Distributed Dynamic Channel Assignment (DDCA) is proposed. It can handle three types of constraints Adjacent Channel Constraint (ACC), Co-Channel Constraint (CCC), Co- Site Constraint (CSC) simultaneously while assigning the channel. Previous methods like Dynamic Channel Selection and Reassignment (DCSR) scheme employs reassignment strategy to maximize the number of unavailable channels becoming available. This scheme transfers an ongoing call of one channel to the released channel if there is relatively lesser number of available channels becoming unavailable due to above mentioned constraints. The results are produced without reassignment. These results are compared with DCSR scheme. New call and handoff call block rates are plotted for comparison.

In cellular networks Device to Device (D2D) communication is used to improve the resource utilization and the throughput. SNR Based Master-Slave Dynamic D2D Communication Algorithm (SMSDCA) is proposed to improve the resource utilization of the cellular network and improved Quality of Service (QoS). It is achieved by allocating some User Equipment (UE) as master in that cluster based on SNR and energy, who communicates with base station and the other UE's by using D2D. Other UE's requesting for data in that cluster are made as slaves. SMSDCA uses dynamic management of clusters and devices. In this we are handling both static and dynamic users need. For non-data requests it allocates the channel as per existence but for data requests SMSDCA will be used. In this algorithm D2D channel will be allocated by base station. Energy of the device is computed based on activities of the user, i.e., voice calls, duration and number of data packets transferred. The master can be changed dynamically based on SNR, energy and movement of device in cluster limit. By using this, the new users requesting for data and users moving from neighboring clusters are taken care accordingly. In this paper MATLAB simulation results shows that by using this algorithm the throughput and number of users can be served will be increased in comparison with Interference aware graph based resource sharing scheme for D2D communication [3]. © 2015 IEEE.

A new method of classifying satellite images into different categories such as forest, desert, river etc., with the help of Support Vector Machine (SVM) and unsupervised learning method. In the past few decades satellite imagery has been used successfully for weather, geographical and geological applications. With the advance of technology, more sophisticated sensors provide higher resolutions, and with faster computer systems, the use of satellite imagery has opened the fields of exploration and application. In this paper we are going to use the unsupervised learning and Support Vector Machine in combination with Fisher's Linear Discriminate Analysis approach to classify the satellite images into the predefined categories. We use the algorithm to detect automatically the different objects like large shopping malls, facility areas, vegetation, ocean bodies etc.

Meera, “Priority Based Time-Division Multiple Access Algorithm for Medium Range Data Communication in Very High Frequency Radios”, Journal of Computational and Theoretical Nanoscience, Volume 17, Number 1, vol. 17, Number 1, 2020.[Abstract]


In this paper, A novel and efficient time division multiple access (TDMA) algorithm for military last-mile data communication is designed. A dynamic slot assignment method coupled with an out-of-band control mechanism is used for the proposed design. In out-of-band, there is a well-defined control segment along with the data segment. So, if a new node specifically a high priority node arrives at the network, it can signal its arrival by a response in the designated mini-slots and can also check the slot in the network, if no idle slots are available. Assigning priority to the nodes would also ensure the delivery of the important messages first. Query messages are broadcasted by the Central node in order to detect new nodes. This reduces nodes working time and also ensures that the nodes don’t interrupt any existing communication. Furthermore, we describe the feasibility and the reliability of this algorithm for military’s last-mile (end user) data communication.
