Research on channel accessing and routing in cognitive wireless Mesh network
认知无线Mesh网络信道接入与路由协议研究*

This paper introduced the multi-path routing protocol into solving the problem of data link failure caused by lack of available idle licensed channel. It would reduce the influence of the link failure by choosing the next hop node that had the intersection of SOP from the several paths. In addition, this protocol avoided the appearance of congested node by utilizing congestion control mechanism. The simulation results demonstrate that, in CWMN, this protocol can reduce the average end-to-end delay, improve the data packet delivery ratio and increase the network throughput effectively.
