%X Multiple channels can increase network capacity by transmitting traffic on different channels in an interference are a. Firstly, this paper proposed an efficient distributed joint routing and channel assignment strategy for cognitive wireless mesh networks. The main purpose of this channel allocation strategy was to maintain the channel diversity in the neighborhood. Simulation results show that compared to the link-based channel allocation algorithm in wireless multi-channel network, the avera-ge throughput approximately increases by 50%, and the average delay reduces by 50% with the new algorithm. Then, also proposed a channel merging algorithm in the channel constrained situation. Simulation results also show that, after the implementation of the channel merging algorithm, the network average throughput and delay performance have been further improved significantly, too.
