中文摘要：
随着无线Mesh网络的发展,在网络中配置节点多射频多信道,提高信道资源的利用率和降低无线干扰,成为扩大网络容量的有效手段。采用了一种基于网络拓扑信息的集中式的多射频多信道分配算法。实现包括信道分配计算、信道分配切换及网络恢复三个阶段。三个阶段依次实现网络的信道干扰最小、确保网络的连通以及节点失败后网络的恢复,并提高网络的容量。仿真结果表明,信道分配算法可以有效地提升网络性能。
英文摘要：
With the development of the wireless mesh network（WMN）,it is an effective way to improve the network capacity using the Multi - Radio Multi - Channel to increase the spatial reuse of the available wireless channels. In this paper,a centralized topology - based Multi - Radio Multi - Channel assignment was proposed,which was divided into the channel calculation phase,the channel switch phase and the network recover phase.Based on the method,we can minimize interference among nodes,maximize connectivity among nodes and recover the network after nodes failed.So the network capacity was improved.The simulation shows that the proposed algorithm can provide a large improvement of the WMN.
