Optimal CSMA: Theory and Practice
Date: 2014/6/3             Browse: 619

Speaker: Dr. Yung Yi, KAIST, South Korea

Time: 6/3, Tuesday, 9:00 to 10:00am

Location: Room 220, Building 8



In this talk, I will summarize my and the community’s research on optimal CSMA, which is a theory-driven, new wireless MAC, ranging from theory to practical implementation. Optimal CSMA has strong merits of achieving such optimality without message passing. Optimal CSMA dates back to the seminal work of max-weight scheduling for throughput optimality and NUM (Network Utility Maximization) for utility optimality for wireless resource allocation. I will also discuss the technical challenges and some solutions for bridging the gap between theory and practice. This talk also discusses how wireless MAC should evolve in the future and what are the remaining challenges there.


Yung Yi received his B.S. and the M.S. in the School of Computer Science and Engineering from Seoul National University, South Korea in 1997 and 1999, respectively, and his Ph.D. in the Department of Electrical and Computer Engineering at the University of Texas at Austin, USA in 2006. From 2006 to 2008, he was a post-doctoral research associate in the Department of Electrical Engineering at Princeton University. Now, he is an associate professor at the Department of Electrical Engineering at KAIST, South Korea. His current research interests include the design and analysis of computer networking and wireless communication systems, especially congestion control, scheduling, and interference management, with applications in wireless ad hoc networks, broadband access networks, economic aspects of communication networks (aka network economics), and green networking systems. He was the recipient of two best paper awards at IEEE SECON 2013 and ACM Mobihoc 2013. He is now an associate editor of IEEE/ACM Transactions on Networking, Journal of Communication Networks, and Elsevier Computer Communications Journal.
