The Case for FEC-Based Reliable Multicast in Wireless Mesh Networks
Many important applications in wireless mesh networks require reliable multicast communication. Previously, Forward Error Correction (FEC) techniques have been proved successful for providing reliability in the Internet, as they avoid the control packet implosion and scalability problems of ARQ-based protocols. In this paper, the authors examine if FEC can be equally efficient in wireless mesh networks. They implement four reliable schemes initially proposed for wired networks on top of ODMRP, a popular unreliable multicast routing protocol for wireless networks.
