| 摘 要： | 从路径交叉的角度为认知无线Mesh网络提出一种新的联合多路径路由和信道分配策略，该策略结合按需路由的基本流程，同时根据所选路径情况设置交叉节点的中继功能，以主用户曾经占用每个信道的最少次数作为衡量标准来选择信道，并给出了一种解决信道冲突的方案。仿真结果表明，所提策略与基于链接、基于干扰的策略相比，能够显著改善平均吞吐量和时延等网络参数性能。

| Abstract: | 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. |
