摘　　要：为解决信道干扰导致无线网状网吞吐量下降的问题,本文提出一种新的基于干扰模型的多信道分配策略.首先对网络进行分层,然后按照优先级逐层进行信道分配,通过降低信道间的干扰来提高每个结点的吞吐量,进而提高整个网络的吞吐量.仿真结果表明了该策略的有效性.Concerning the problem of decrease in Wireless Mesh Network（WMN）throughput caused by channel interference, this paper proposes a new multi-channel allocation strategy based on the interference model. This strategy first stratifies WMN and then allocates channels according to the priority of layers. By alleviating channel interference of the network, it promotes each node＇s throughput in WMN and thus to increase the network throughput. The simulation results show that the strategy is efficient.
