Systems with multiple channels and multiple radios per node have been shown to enhance throughput of Wireless Mesh Networks (WMNs). Recently, network coding has also been proved to be a promising technique for improving network throughput of WMNs. However, the performance of network coding in the context of multicast in Multi-Channel Multi-Radio (MCMR) WMNs is still unknown. In this paper, the authors present a comprehensive performance evaluation of network-coded multicast in MCMR WMNs using extensive simulations, realistic network settings and meaningful performance metrics such as throughput, file completion time, packet end-to-end delay, and packet delivery ratio under a wide range of scenarios.
