摘要： 针对IEEE 802.11多射频多信道无线Mesh网络，提出一种基于链路质量的分布式信道分配算法，通过信道扫描收集所有信道信息，根据链路质量决定工作信道，同时在网络发生变化时对信道进行动态调整。仿真实验结果表明，与常用的集中式信道分配算法相比，该算法更能有效提升网络容量。

Abstract: A link quality-based distributed channel assignment algorithm in IEEE 802.11 Wireless Mesh Network(WMN) is presented. It scans to collect all the channels information and assigns channels according to link quality. The algorithm can adjust channel dynamically when the network topology or link quality changes. Simulation results demonstrate that, compared with centralized channel assignment algorithm, this algorithm can improve network throughput significantly.
