Load-Balancing Channel Assignment Algorithms for a Multi-Radio Multi-Channel Wireless Mesh Networks

Abstract

Capacity in multi-radio multi-channel wireless mesh networks can be greatly enhanced by adopting effective load balancing algorithms.In this work, a new channel allocation algorithm is proposed by considering inter-channel interference and load balance issue to maximize network capacity.The algorithm can choose a best channel based on channel interference caused by neighbor nodes and then to allocate the channel to a link so that it can bear more traffic and reduce network congestion.By comparison with the other two typical channel allocation algorithms available, it's found that our proposed algorithm has better network performance in case of heavy network load.
