Information theory is well poised to tremendously impact the design of distributed wireless networks of the future, such as ad-hoc networks. However, the challenge is that most network information theory problems are notoriously difficult and the mathematical barriers that must be overcome are quite high. In this talk, I will discuss our approach to overcome this challenge, which is based on developing simple, deterministic channel models that capture the main features of the wireless medium, and utilizing them to approximate more complex models. In particular, I will discuss the applications of our approach to "relay networks" and "interference networks with local network views".

The first part of this talk is based on collaboration with Suhas Diggavi and David Tse, and the second part is based on collaboration with Vaneet Aggarwal and Ashutosh Sabharwal.


Salman Avestimehr is currently an assistant Professor at the School of Electrical and Computer Engineering at Cornell University. He received his Ph.D. in 2008 and M.S. degree in 2005 in Electrical Engineering and Computer Science, both from the University of California, Berkeley. Prior to that, he obtained his B.S. in Electrical Engineering from Sharif University of Technology in 2003. He was also a postdoctoral scholar at the Center for the Mathematics of Information (CMI) at Caltech in 2008. He has received a number of awards including the NSF CAREER award (2010), the David J. Sakrison Memorial Prize from the U.C. Berkeley EECS Department (2008), and the Vodafone U.S. Foundation Fellows Initiative Research Merit Award (2005). His research interests include information theory, communications, and networking.
