摘　　要：本文针对无线Mesh网络主干网部署变动少的特性,设计了多信道无线Mesh网络中DSDV路由算法,利用OMNeT++5.3对DSDV路由原算法和改进后算法进行仿真对比,在仿真时间、消息数量、网络传输参数相同情况下,主要从丢包数量情况进行统计,仿真结果证明当消息都发往同一个地址时,算法改进前后没有太大差别,当消息发往全网任意一个地址时,改进后的多信道DSDV算法丢包量明显少于改进前的DSDV算法,而且在同等条件下,消息缓存容量大的丢包量会明显减少。In view of the characteristics of less change in deployment of backbone network in wireless Mesh network,this paper designs the DSDV routing algorithm in mufti-channel wireless Mesh network.The original and improved DSDV routing algorithms are simulated and compared by OMNeT++5.3.When the simulation time,number of messages and network transmission parameters are the same,the simulation results show that when all messages are sent to the same address,there is no significant difference between the improved algorithm and the improved multi-channel DSDV algorithm.When messages are sent to any address in the whole network,the improved multi-channel DSDV algorithm is obviously better than the improved DSDV algorithm.Moreover,under the same conditions,the large capacity of message cache will significantly reduce the amount of packet loss,which also confirms that the improved algorithm is in line with scientific logic.Moreover,under the same conditions,the large capacity of message cache can significantly reduce the count of lost package.
