On the Benefits of Network Coding for Wired and Wireless Applications
By Joerg Widmer – DoCoMo, Munich

Session Chair: Patrick Senac

Abstract:

Network coding is a very recent area of information theory, proposed by Ahlswede et. al. in 2000. With network coding, intermediate nodes in the network 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 support P2P applications in wired networks and for routing in wireless mesh networks. In particular, the broadcast nature of the wireless medium facilitates the design of efficient opportunistic algorithms. This talk will give an introduction to the theory of network coding and then explore the specific challenges and benefits of network coding in wired and wireless networks in more detail.

Biography of J. Widmer

Joerg Widmer is project manager of the Ubiquitous Networking Research Group at DoCoMo Euro-Labs in Munich, Germany. The group's researchers covers a wide range of topics, from overlay networks and security research all the way down to MAC layer and physical layer design for wireless networks. His specific research interests concern efficient algorithms for wireless networks, network coding, and transport protocols. Before joining DoCoMo, Joerg Widmer spent two years as postdoctoral researcher at EPFL, Switzerland, doing research on ultra-wide band networks. Joerg Widmer obtained his M.S. degree and Ph.D. degree in computer science from the University of Mannheim, Germany in 2000 and 2003, respectively. In 1999 and 2000, he was a visiting researcher the ICSI Center for Internet Research, Berkeley, CA working on equation-based congestion control.
