A multiple channel routing protocol for wireless mesh networks
Xiaochuan Shi, Zhen Xu · 2010
This paper proposes a distributed channel assignment algorithm CLBCA (Channel Load Based Channel Assignment) and a hybrid routing protocol TOIRP for multi-channel wireless mesh networks. A new routing metric CETTI is proposed for its advantage of quantifying the interference of communication by distinguishing interference into inter-flow interference and intra-flow interference. The channel assignment algorithm is divided into two phases: radio-neighbor binding and channel-radio binding. This channel assignment algorithm seeks the full use of each channel yet avoids the channel-dependency problem which is common in the multi-channel environment. Simulation results show that TOIRP has better throughput and less delay.
