Radio resource management is of central importance in emerging heterogeneous networks. As the size of cells continues to shrink, traffic variations over time in a given cell become increasingly pronounced. Adapting resource allocation across cells to their traffic conditions is both rewarding and challenging. In this talk, we describe a framework for modeling the topology of a multi-cell system, the dynamic traffic, user association, and spectrum allocation on a relatively slow timescale. We formulate convex and nonconvex optimization problems that can be solved efficiently to minimize the average packet sojourn time in a network of up to dozens of cells. Simulation shows significant throughput and delay advantages over optimized static allocation schemes. This is joint work with Binnan Zhuang, Michael L. Honig, and Ermin Wei.


Dongning Guo joined the Department of Electrical Engineering and Computer Science at Northwestern University, Evanston, IL, in 2004, where he has been promoted to Professor.  He received the B.Eng. degree from the University of Science and Technology of China, the M.Eng. degree from the National University of Singapore, and the M.A. and Ph.D. degrees from Princeton University, Princeton, NJ. He has been an Associate Editor of IEEE Transactions on Information Theory, an Editor of Foundations and Trends in Communications and Information Theory, and a Guest Editor for the IEEE Journal on Selected Areas in Communications. He is a co-recipient of the IEEE Marconi Prize Paper Award in Wireless Communications in 2010 and also a recipient of the National Science Foundation Faculty Early Career Development (CAREER) Award in 2007.
