Performance Evaluation of Network-Coded Multicast in Multi-Channel Multi-Radio Wireless Mesh Networks

Free registration required

Executive Summary

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.
