Venue: FIT 1-312


This talk reviews recent advances on network control for wireless networks with stochastic traffic and time-varying channel conditions. We start with a review of the seminal work of Tassiulas and Ephremides on optimal scheduling and routing, i.e., the now famous backpressure algorithm. Despite its theoretical promise, the optimal control strategy has not taken hold in practice; due, in part, to some of the modeling assumptions that fail to take into account practical considerations. Thus, we will discuss recent efforts to develop variants of backpressure that take into account practical considerations. These include efficient distributed scheduling algorithms, as well as new algorithms that take into account practical hardware and protocol limitations.

Short Bio:

Eytan Modiano received his B.S. degree in Electrical Engineering and Computer Science from the University of Connecticut at Storrs in 1986 and his M.S. and PhD degrees, both in Electrical Engineering, from the University of Maryland, College Park, MD, in 1989 and 1992 respectively. He was a Naval Research Laboratory Fellow between 1987 and 1992 and a National Research Council Post Doctoral Fellow during 1992-1993. Between 1993 and 1999 he was with MIT Lincoln Laboratory where he was a project leader for MIT Lincoln Laboratory's Next Generation Internet (NGI) project. Since 1999 he has been on the faculty at MIT, where he is a Professor in the Department of Aeronautics and Astronautics and the Laboratory for Information and Decision Systems (LIDS). His research is on communication networks and protocols with emphasis on satellite, wireless, and optical networks. He is an Editor-at-Large for IEEE/ACM Transactions on Networking, and served as Associate Editor for IEEE Transactions on Information Theory, the IEEE/ACM Transactions on Networking, and the AIAA Journal of Aerospace Information Systems. He was the Technical Program co-chair for IEEE Wiopt 2006, IEEE Infocom 2007, and ACM MobiHoc 2007. He is a Fellow of the IEEE and an Associate Fellow of the AIAA.
