Abstract: Caching has been successfully exploited in the Internet for many years through content distribution networks. With the growing number of wireless users and their increasing appetite for high rate content, particularly video streaming applications, caching is now moving towards the wireless network edge, where popular contents are stored either at access points, or directly at user devices. Caching at the network edge reduces both the latency of content delivery and the traffic on the backhaul links, and increases spatial reuse, practically turning relatively abundant and cheap cache memories into extremely valuable and scarce wireless bandwidth. In this talk I will overview some of the recent developments in wireless content caching in my research group including fundamental information theoretic analysis as well as learning theoretic approaches to optimal proactive caching. Speaker's bio: Deniz Gunduz received his Ph.D. degree in electrical engineering from NYU Polytechnic School of Engineering in 2007. After his PhD he served as a postdoctoral research associate at Princeton University, and as a consulting assistant professor at Stanford University. Before joining Imperial College London he was a researcher at CTTC in Barcelona, Spain. Currently he is a Reader (Associate Professor) in Information Theory and Communications in the Electrical and Electronic Engineering Department of Imperial College London, and leads the Information Processing and Communications Lab. Dr. Gunduz is an Editor of the IEEE Transactions on Communications, and IEEE Transactions on Green Communications and Networking. He is the recipient of a Starting Grant of the European Research Council (ERC), the 2014 IEEE Communications Society Best Young Researcher Award for the Europe, Middle East, and Africa Region, Best Paper Award at the 2016 IEEE Wireless Communications and Networking Conference (WCNC), and the Best Student Paper Award at the 2007 IEEE International Symposium on Information Theory (ISIT).
