Wireless MAC Protocols for Ad Hoc Networking

 

In the last few years, there has been a big interest in Ad Hoc Wireless Networks as they have tremendous military and commercial potential. An Ad Hoc Wireless Network is a wireless network, comprising of mobile nodes (which can also serve as routers) that use wireless transmission, having no infrastructure (central administration such as a Base Station in a Cellular Wireless Network or an Access Point in a Wireless LAN). Ad Hoc Wireless Networks can be set up anywhere and anytime as they eliminate the complexities of infrastructure setup. Ad Hoc wireless Networks find applications in several areas. Some of these include: military applications (establishing communication among a group of soldiers for tactical operations as setting up of a fixed infrastructure in enemy territories or in inhospitable terrains may not be possible), collaborative and distributed computing, emergency operations, wireless mesh networks, wireless sensor networks, and hybrid (integrated Cellular and Ad hoc) wireless networks. In this talk, I first present a brief overview of the major issues that influence the design and performance of Ad Hoc Wireless Networks. As the performance of any wireless network hinges on the Medium Access Control (MAC) protocol, more so for Ad Hoc Wireless Networks, I present, in detail, three recently proposed MAC protocols for Ad Hoc Networks.

 

Biography:

 

C. Siva Ram Murthy received the Ph.D. degree in Computer Science from the Indian Institute of Science, Bangalore in 1988. Since then he has been on the faculty of the Department of Computer Science and Engineering at the Indian Institute of Technology, Madras. He is currently a Professor with the same department since September 2000. He has held visiting positions at the German National Research Centre for Information Technology (GMD), Bonn, Germany, the University of Stuttgart, Germany, the University of Freiburg, Germany, the Swiss Federal Institute of Technology (EPFL), Switzerland, and the University of Washington, Seattle, USA. He is the co-author of the textbooks Resource Management in Real-time Systems and Networks, (MIT Press, Cambridge, Massachusetts, USA), WDM Optical Networks: Concepts, Design, and Algorithms, (Prentice Hall, Upper Saddle River, New Jersey, USA), and Ad Hoc Wireless Networks: Architectures and Protocols, (Prentice Hall, Upper Saddle River, New Jersey, USA). His research interests include parallel and distributed computing, real-time systems, lightwave networks, and wireless networks. He has published more than 120 international journal and 100 international conference papers in these areas. Dr.Murthy is a recipient of Best Ph.D. Thesis Award from the Indian Institute of Science, Indian National Science Academy (INSA) Medal for Young Scientists, and Dr. Vikram Sarabhai Research Award. He is a co-recipient of Best Paper Awards from the 5th IEEE International Workshop on Parallel and Distributed Real-Time Systems (WPDRTS), and the 6th and 11th IEEE Annual International Conference on High Performance Computing (HiPC). He is a Fellow of the Indian National Academy of Engineering, an Associate Editor of IEEE Transactions on Computers, and a Subject Area Editor of Journal of Parallel and Distributed Computing.
