Title: Graphical Congestion Games with Applications in Spectrum Sharing
Abstract: The classical congestion game (introduced by Rosenthal in 1973) nicely captures the interactions between selfish players competing for limited resources, and has found many applications in economics, communications, networking, ecology, and sociology. However, such model does not capture the spatial relationships between players, which are critical for many applications. This motivates the study of graphical congestion game, which models the spatial relationships by a graph. In this talk, we will discuss several recent results on graphical congestion games, focusing on those with player-specific and resource-specific payoff functions on weighted directed graphs. We will also discuss how these models can help us to understand dynamic spectrum sharing in distributed wireless networks.
Jianwei Huang is an Assistant Professor in the Department of Information Engineering at the Chinese University of Hong Kong. He received Ph.D. in Electrical and Computer Engineering from Northwestern University in 2005, and worked as a Postdoc Research Associate in the Department of Electrical Engineering at Princeton University during 2005-2007. He was a visiting scholar at Ecole Polytechnique Federale De Lausanne (EPFL) and University of California-Berkeley.
Dr. Huang currently leads the Network Communications and Economics Lab (ncel.ie.cuhk.edu.hk), with the main research focus on nonlinear optimization and game theoretical analysis of networks, especially on network economics, cognitive radio networks, and smart grid. He is the recipient of the IEEE SmartGridComm Best Paper Award 2012, the IEEE Marconi Prize Paper Award in Wireless Communications in 2011, the International Conference on Wireless Internet Best Paper Award 2011, the IEEE GLOBECOM Best Paper Award in 2010, Asia-Pacific Conference on Communications Best Paper Award in 2009, and the IEEE ComSoc Asia-Pacific Outstanding Young Researcher Award in 2009.
