Network coding is a recent area of information theory, that allows intermediate nodes in the network to not only forward but also process the incoming information flows (i.e., they may perform coding on the packets they receive). Among the benefits that network coding can offer are a higher throughput, a reduction in delay, better energy efficiency, potentially lower complexity algorithms for information dissemination, and a high degree of robustness to packet loss. Network coding has been successfully applied, for example, to improve forwarding in wireless mesh networks. In particular, the broadcast nature of the wireless medium facilitates the design of efficient opportunistic algorithms. This talk gives an introduction to network coding and explores some of the applications and challenges of network coding in wireless networks, such as low delay network coded broadcast, coding for relay networks, and compressive sensing.
Since September 2010, Joerg Widmer is Senior Researcher at Institute IMDEA Networks. From June 2005 to July 2010, he was manager of the Ubiquitous Networking Research Group at DOCOMO Euro-Labs in Munich, Germany, working on several projects in the area of wired and wireless networking. Before joining DOCOMO Euro-Labs, he was senior researcher in the group of Prof. Jean-Yves Le Boudec at EPFL. There, his main research focus was on UWB networks and MAC layer design as well as network coding in wireless networks. Joerg Widmer received his M.S. and PhD degrees in computer science from the University of Mannheim, Germany in 2000 and 2003, respectively. In 1999 and 2000 he was a visiting researcher at the ICSI Center for Internet Research in Berkeley, CA, USA.
