Network coding for wireless networking
Vendredi 3 juin 2005Jim KUROSE professeur à UMASS (USA), et de Muriel MEDARD professeur au MIT (USA).
Network coding has recently emerged as an effective method to go beyond traditional route-based networks. While network coding allows certain traffic matrices that are infeasible with traditional routing to be achievable, it is possible that its main benefits for networking may lie mainly in the way that network coding allows for efficient, distributed operation. We overview recent results in the area of distributed network coding and discuss network coding for cost minimization and erasure handling, with an emphasis on wireless networks. Distributed network coding yields a reduction in cost, say energy use in a wireless context, and to network capacity-achieving performance in erasure settings, such as the ones associated with wireless channels. We discuss the possible implications for wireless networks and present some open problems in the area.
