S. Kumar, Preeja Pradeep, Sumesh Kj, and N., J., “Detection of SPAM attacks in the remote triggered WSN experiments”, Lecture Notes in Electrical Engineering, vol. 376, pp. 715-727, 2016.[Abstract]


Spam attack is the deliberate delivery of unsolicited or unwanted messages across the computer networks with the intention to deplete the resources that results in Denial of Service (DoS) to the end user. This is more important to consider in Wireless sensor networks test beds where the nodes already have only little computing resources (4kb RAM), and low network bandwidth for their applications. The Remote Triggered WSN test bed (http://vlab.amrita.edu/?sub=78) that we have deployed in our university consists of more than 80 nodes connected with various sensors, digital multimeters etc., allows any student in the internet to upload their programs, execute them and view their experiment results with real time video streaming to learn the WSN concepts intuitively. Hence, there is a need to detect such type of spam attacks in the test bed, in case, a user uploads the malicious programs that affects the functioning of nodes in other experiments. We have tried two packet inspection techniques, Gaussian Naive Bayes (GNB) and k-Nearest Neighbour (K-NN) for learning the pattern and identifying whether the new incoming message is Spam or Non-spam. It is observed that the GNB method could catch spam messages at 94-96% Accuracy, with only 5-10% false positive rate (FPR). It is also found that the performance of k-NN gradually decreases as k-value increases. The complexity and execution speed becomes worse at larger k-values where as they are invariant in case of GNB. Hence it shows GNB is more appropriate than k-NN for inspecting the messages. © Springer Science+Business Media Singapore 2016.

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.

Tunnels are considered as the oldest method of passageway. Underground tunnels are popular from olden eras for connecting places, travelling, and aid for various surface threats. They are also used for illegal activities like smuggling of unlicensed drugs, weapons, currency, gold, explosives, and even human trafficking is being done through these tunnels. These immoral activities are concentrated in national border areas in order to escape from the border security measures. Hence the detection processes of such tunnels in the national security border areas are necessary in order to protect our homeland security systems. The geology plays an important role in the detection of the underground tunnel system procedures. There is no perfect system for the tunnel detection and localization and even today the tunnels revealed in coincidence. The basic principle to find the hollow space (tunnel) is, by sending an ultrasonic frequency signal into the ground, and study the reflected beam from the tunnel or the hollow space. By analyzing the reflected signal characteristics, preliminary detection of a tunnel/void is possible. Basic idea of the detection is to perform the range estimation algorithm (REA) by pulse echo method. From these, we can estimate the depth of the tunnel. The characteristics of the signal at the soil-tunnel (air) reflection interface are to be investigated. © Springer India 2016.

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. Our WSN testbed consists of more than 150 sensor nodes deployed in indoor and outdoor environment. 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.

Preeja Pradeep, “Research Domains for Cognitive Radio: A Survey”, in IT Convergence and Security (ICITCS), 2015 5th International Conference on, 2015.[Abstract]


Cognitive Radio (CR) is one of the most transformative innovation recently emerged in the field of Wireless Networks. CR is famous due to the limited electromagnetic spectrum and the fixed spectrum assignment policy. CR technology helps to solve the spectrum scarcity problem by using its intelligent radio which senses and adapts to the environment. It locates the unused radio spectrum which is allocated to the licensed users and helps to reallocate the unused spectrum to unlicensed users thereby improving the utilization of the spectrum. This paper points out various challenges and limitations faced by areas such as wireless sensor networks, vehicular networks, smart grid, healthcare, and public safety networks and highlights the improvements made to the utilization of the spectrum as well as the quality of communication, which makes these networks more efficient. An overview of CR along with its various research domains are presented in the paper. More »»

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.

Chennai, India, 2015.[Abstract]


Smartphone usage has reached its peak. There has been a tremendous growth in the number of people migrating from PCs to smart phones. Numerous scenarios such as loss of a phone, phone theft etc., can lead to unauthorized use of one’s own smartphone. This raises the concern for securing personal and private data. This project proposes a light weight two level user identification scheme to recognize and authenticate the mobile phone based on the device holding and usage patterns. To validate the proposed scheme, an application is created which takes a gesture input characterized by time of swiping the screen, finger pressure, phone movements and location of swipe on the screen through X and Y co-ordinate. A
threshold based matching scheme performs classification to find the true owner. Results show that the scheme was able to achieve 90% true positives and 10% false positives with a 0.5% of battery usage.

Driving at night causes approximately 50% of traffic fatalities; one of the primary causes being the usage of headlights on high beam. Courteous drivers usually lower their headlights from high to low beam when they see oncoming traffic. However, due to driver inertia, either inherent and/or caused by frequent switching between high and low beams, headlights are eventually left in high beam. This causes temporary blindness in drivers from on-coming traffic, leading to accidents, as well as permanent blindness in frequent nighttime drivers. In this paper, we propose a novel system to automatically attenuate the headlights of oncoming traffic and thereby reduce driver discomfort. We use a consensual and coordinated communication approach in order to request oncoming traffic to lower their headlights to low beam when necessary and lower our own headlights as well. Experiments conducted show that it is possible to automatically attenuate light intensity from on-coming traffic in fractions of a second, at significantly large distances, thereby reducing driver discomfort and mitigating accidents significantly.

Jamming-based denial of service attacks are a real threat in wireless sensor networks. This paper studies and analyzes the impact of jamming on micaz motes running TinyOS and explores ways to mitigate the impact. Jamming is facilitated by disabling carrier sensing on the jammer nodes. Jamming attack is detected by tracking RSSI and PDR at the receiver. By varying several parameters at the sender such as power level, packet size, distance from the jammer etc., various jamming mitigation methods are explored and the results presented along with theoretical analysis.
