摘　　要：针对无线Mesh网络中由于无线信号干扰而造成的端到端吞吐量并不理想问题,提出一种采用功率控制构造无线Mesh网络拓扑的算法,通过调整节点的传输功率到一个合理的水平来降低干扰以提高信道的空间复用度,从而改善网络的吞吐量。结合流量模型和干扰模型计算整个网络的吞吐量。仿真结果表明,该拓扑控制能够提高无线Mesh网络的吞吐量。To solve poor end-to-end throughput resulted from wireless signal interference in Wireless Mesh Networks（WMN）,a topology control algorithm is proposed,which using power control.The algorithm is carried out by adjusting the transmission power of each node to a reasonable level to reduce interference and improve the spatial reuse of the channel,which gives rise to the improved network throughput.The throughput is calculated with the traffic model and the interference model.Results show that the throughput of WMN can be substantially increased with topology control.
