Abstract: Cross-layer control have become one of the most dynamically developing research areas of wireless networking in the recent decade. In this talk, we present overview of long-term network utility maximization problem which exploits opportunism in channels, queues and space. Jointly throughput-optimal scheduling, routing and flow control are discused in cellular networks and mesh networks, including the issues of power control, load balancing and subcarrier allocation. We also discuss technical challenges in developing practical cross-layer protocols from the theory and present our on-going efforts to tackle these challenges.
Short Bio: Professor Song Chong received his B.S. and M.S. degrees in Control and Instrumentation Engineering from Seoul National University, Seoul, Korea, in 1988 and 1990, respectively, and the Ph.D. degree in Electrical and Computer Engineering from the University of Texas at Austin in 1995. In March 2000, he joined the Department of Electrical Engineering and Computer Science, Korea Advanced Institute of Science and Technology (KAIST), Taejon, Korea. He is currently an Associate Professor, leading the Network Systems Laboratory. Prior to joining KAIST, he was with the Performance Analysis Department, AT&T Bell Laboratories, Holmdel, New Jersey, as a Member of Technical Staff. His research interests include future Internet, wireless networks and performance evaluation. He has published more than 60 papers in international journals and conferences and holds three U.S. patents in these areas. He is currently an Editor of the Journal of Communications and Networks. He has served as a Technical Program Committee member of IEEE INFOCOM'97, '99, '03, IEEE ICC'05, IEEE GLOBECOM '05, IEEE VTC '06, WiOpt '07, '08, an Organizing Committee member of PV '01, a Program Committee member of PV `02, `03, `04, a Technical Program Co-chair of ICBN '04. He currently serves as an officer of IEEE ComSoc Technical Committee on Computer Communications, an officer of IEEE ComSoc Asia Pacific Board, and a chair of wireless working group on Future Internet Forum (FIF) in Korea and AsiaFI (Asia Future Internet) forum.
