Joint Multi-path Routing and Channel Assignment Strategy for Cognitive Wireless Mesh Networks
Zhihua Bao · 2011
In this paper,a novel joint multi-path routing and channel assignment strategy based on path crossing for the cognitive wireless mesh networks was proposed.The strategy combines the basic processes of on-demand routing,and sets up the relay function of cross-nodes according to the chosen routes,then selects the channel based on the minimum number of channels occupied by the primary users,and finally gives a solution to channel conflict.Simulation results show that,compared with the link-based and interference-based strategy,the new strategy has an obvious advantage in the performance of delay and throughput.
