Information and Inference in the Wireless Physical Layer

Refreshments: 10:45 a.m.
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. SPEAKER'S BIOGRAPHY H.
