Node Interactions in Wireless Networks: Competition and Cooperation

Potential modes of interaction among nodes in wireless networks have become increasingly complex, as more flexible network architectures emerge, as the processing power of individual nodes increases, and as greater efficiencies in the use of radio resources are needed. These node interactions can be either competitive or cooperative. Examples of competitive behavior among wireless nodes arise in areas such as cognitive radio, secure transmission, and in game theoretic modeling. Examples of cooperative behavior arise in network coding, cooperative transmission and relaying, multi-hop transmission and coalition games, collaborative beam-forming and collaborative inference. This talk will illuminate this issue of node interaction through discussion of a number of specific examples.

Biography: In addition to his role as dean, H. Vincent Poor (Ph.D. in EECS, Princeton, 1977) is the Michael Henry Strater University Professor of Electrical Engineering at Princeton, where his interests lie in the areas of statistical signal processing and stochastic analysis, and their applications in wireless networking, finance and related fields. He is also affiliated with Princeton’s Program in Applied & Computational Mathematics and its Department of Operations Research and Financial Engineering. From 1977 until joining the Princeton faculty in 1990, he was a faculty member at the University of Illinois at Urbana-Champaign. He has also held visiting appointments at a number of universities and research institutions in the USA and abroad, including recently Imperial College (London), Stanford and Harvard. Dr. Poor is a member of the National Academy of Engineering, a Fellow of the American Academy of Arts & Sciences, and a former Guggenheim Fellow. He is also a Fellow of the IEEE, the Institute of Mathematical Statistics, the Optical Society of America, and other scientific and technical organizations. He has served as President of the IEEE Information Theory Society, and as Editor-in-Chief of the IEEE Transactions on Information Theory. Recent recognition of his work includes the 2005 IEEE Education Medal and the 2007 IEEE Marconi Prize Paper Award.
