Distributed Optimization for Cognitive Radio Networks Using Game Theory

Dr. Yong Xiao

Massachusetts Institute of Technology

electrical engineering and computer science

postdoctoral fellow


  Cognitive radio (CR) is one of the main technologies to solve the spectrum under-utilization problem in future generations of wireless systems. In this talk, we will introduce a game theoretic framework for cognitive radio (CR) wireless networks in which each user could adapt the parameters and operations according to the dynamic environment and its past experience to achieve optimal performance of itself as well as the equilibrium point of the whole network. By combining recent results in information theory, wireless network, control theory, and artificial intelligence, we establish a series of distributed learning algorithms for each user to improve its performance without causing adverse effects on others.


 Yong Xiao received his B.S. degree in electrical engineering from China University of Geosciences, Wuhan, China in 2002, M.Sc. degree in telecommunication from Hong Kong University of Science and Technology in 2006, and his Ph. D degree in electrical and electronic engineering from Nanyang Technological University, Singapore in 2012. From August 2010 to April 2011, he was a research associate in school of electrical and electronic engineering, Nanyang Technological University, Singapore. From May 2011 to October 2012, he was a research fellow at CTVR, school of computer science and statistics, Trinity College Dublin, Ireland. From November 2012, he will be a MIT-SUTD postdoctoral fellow in department of electrical engineering and computer science, Massachusetts Institute of Technology. His research interests include information theory for cooperative communication systems, machine learning and application of game theory in multi-user wireless networks.
