Abstract: Wireless networking applications continue to motivate challenging problems in information theory, signal processing, and other fields. A salient feature of wireless networks is the close interaction between the physical layer and the other networking layers. This phenomenon is a result of the principal distinguishing features of wireless, namely mobility and the importance of physical properties (diffusion, interference, fading and radio geometry) in determining link characteristics. For example, the applications layer interacts considerably with the physical layer, as is well known through the importance of quality-of-service in wireless network design. This talk will explore briefly four research areas, primarily involving information theoretic or inferential problems, each of which is motivated by an applications-layer issue. In particular, the four applications of file transfer, inference, real-time multimedia transmission, and social networking, will be used to motivate consideration of four respective research problems involving the physical layer: physical layer security in data networks, distributed inference in sensor networks, finite-blocklength capacity in multimedia networks, and connectivity in small-world networks. Recent progress in each of these four research areas will be reviewed.

Bio: H. Vincent Poor is the Michael Henry Strater University Professor of Electrical Engineering at Princeton University, where he is also Dean of the School of Engineering and Applied Science. His current research interests lie primarily in the area of wireless networking and related fields. Among his publications in these areas are the recent books MIMO Wireless Communications (Cambridge, 2007), Quickest Detection (Cambridge, 2009) and Information Theoretic Security (NOW, 2009). Dr. Poor is a member of the U.S. National Academy of Engineering, and is a Fellow of the IEEE , the American Academy of Arts & Sciences and the Royal Academy of Engineering. He has served as President of the IEEE Information Theory Society, and as Editor-in-Chief of the IEEE Transactions on Information Theory. He has spent three sabbatical leaves at Imperial College, in 1985, 1993 and 2003, the latter as a Guggenheim Fellow. Recent recognition of this work includes the 2005 IEEE Education Medal, the 2009 Edwin Armstrong Award of the IEEE Communications Society, and the 2010 IET Ambrose Fleming Medal.
