With wireless LANs becoming widespread, and with many applications of ad hoc networking on the horizon, optimization of wireless networks is becoming an increasingly important problem. Due to the unique characteristics of the wireless channel, such optimizations at higher layers of the protocol stack require attention to the physical layer mechanisms. This talk will focus on such interactions between medium access control (MAC) protocols and the physical layer. I will illustrate these interactions with examples of MAC protocols that can perform power control, MAC protocols for directional antennas, and misbehavior at the MAC layer.

Vaidya presenting

 

Nitin Vaidya received the Ph.D. from the University of Massachusetts at Amherst. He is presently an Associate Professor of Electrical and Computer Engineering at the University of Illinois at Urbana-Champaign (UIUC). He has held visiting positions at Microsoft Research, Sun Microsystems and the Indian Institute of Technology-Bombay. His current research is in the areas of wireless networking and mobile computing. His research has been funded by various agencies, including the National Science Foundation, DARPA, Motorola, Microsoft Research and Sun Microsystems. Nitin Vaidya is a recipient of a CAREER award from the National Science Foundation. Nitin has served on the committees of several conferences, including as program co-chair for the 2003 ACM MobiCom and General Chair for 2001 ACM MobiHoc. He has served as editor for several journals. He presently serves as the Editor-in-Chief of the ACM SIGMOBILE periodical MC2R, and will assume duties as the Editor-in-Chief of the IEEE Transactions on Mobile Computing from January 2005. He is a senior member of the IEEE and a member of the ACM. For more information, please visit http://www.crhc.uiuc.edu/~nhv/.
