Mesh Router Coordinated Relay Selection for Multicast Cooperative Communications in WMN

In this paper, we address the issue of multicast cooperative communications over WMNs. Specifically, we propose a new framework where mesh router is in charge of the cooperation of mesh clients during a multicast session. Under this framework, we identify the selection of relaying nodes as a critical step to success. To solve above problem, we further develop the concept of in/out-group cooperation as well as the heuristics to find the optimal relay solution. Extensive simulation results show that our approach can considerably mitigate the transmission errors in wireless multicast environment with high efficiency.
