Title of talk : Clock Synchronization in Networks

Abstract

We address the problem of how to synchronize clocks in a wireless network. We present fundamental impossibility and feasibility results, an algorithm, its scaling properties, comparative performance results in an implementation, and a tracking application employing synchronized clocks. Joint work with R. Solis, V. Borkar, A. Giridhar and N. Freris.

Short Bio

P. R. Kumar obtained his B. Tech. degree in Electrical Engineering (Electronics) from I.I.T., Madras in 1973, and the M.S. and D.Sc. degrees in Systems Science and Mathematics from Washington University, St. Louis in 1975 and 1977, respectively.

From 1977 to 1984 he was a faculty member in the Department of Mathematics at the University of Maryland, Baltimore County. Since 1985 he has been at the University of Illinois, Urbana-Champaign, where he is currently Franklin W. Woeltge Professor of Electrical and Computer Engineering, and a Research Professor in the Coordinated Science Laboratory.

He has worked on problems in game theory, adaptive control, stochastic systems, simulated annealing, neural networks, machine learning, queuing networks, manufacturing systems, scheduling, and wafer fabrication plants. His current research interests are in wireless networks, sensor networks, and networked embedded control systems.

He received the Donald P. Eckman award of the American Automatic Control Council, the IEEE Field Award in Control Systems, the Fred W. Ellersick Prize of the IEEE Communications Society, is a Fellow of the IEEE, and a member of the US National Academy of Engineering.
