In our projects in the Indian Institute of Science, we have recently worked on designing WSNs for human intruder detection and for industrial sensing. The effective design of WSNs for such applications requires novel algorithmic techniques in signal processing, communication and networking. I will provide an overview of some of our work on the following problems.
1) Wireless mesh network design for industrial WSNs: We have addressed the problem of optimal relay
placement with performance objectives such as minimum number of relays, end-to-end packet delay bound, and network lifetime.
2) Distributed event detection: We have extended and solved classical change detection formulations to
incorporate communication delays and node energy.
3) Optimal geographical packet forwarding in sleep-wake cycling WSNs: We have developed an optimal
forwarding algorithm that accounts for the trade-off between forwarding delay and selecting a suitable relay.
4) Hop-count based node localisation in dense WSNs: We have mathematically analysed the hop-count and distance relationship on random geometric graphs, and devised improved localisation algorithms.
Biography:
Professor Anurag Kumar obtained his B.Tech. degree from the Indian Institute of Technology at Kanpur (where he was awarded the President’s Gold Medal) and the PhD degree from Cornell University, both in Electrical Engineering. He was then with Bell Laboratories, in New Jersey, for over 6 years. Since 1988 he has been with the Indian Institute of Science (IISc), Bangalore, in the Dept. of Electrical Communication Engineering, where he is now a Professor, and is also the Chair of the Electrical Sciences Division. From 1988 to 2003 he was the Coordinator at IISc of the Education and Research Network Project (ERNET), India’s first wide-area packet switching network. His area of research is communication networking, specifically, modeling, analysis, control and optimisation problems arising in communication networks and distributed systems. Recently his research has focused primarily on wireless networking. He has been elected Fellow of the IEEE, the Indian National Science Academy (INSA), the Indian National Academy of Engineering (INAE), and the Indian Academy of Science (IASc). He received IISc’s Award for Excellence in Engineering Research for 2008. He was an associate editor of IEEE Transactions on Networking, and of IEEE Communications Surveys and Tutorials. He is a coauthor of the postgraduate textbooks “Communication Networking: An Analytical Approach,” (published in 2004) and “Wireless Networking” (published in March 2008), both by Kumar, Manjunath and Kuri, and published by Morgan-Kaufman/Elsevier.
