基于预测时延的无线mesh网络组播路由算法

摘要

Based on analyzing the characteristics of wireless mesh network and the influence of routing,multicast routing algorithm based on prediction propagation delay time is proposed, this algorithm chooses the least transmission delay paths from source node to destination nodes, through the path combining, came into being multicast routing tree. The routing algorithm has the QoS of low delay guarantee and has local repair ability. The algorithm is simulated based on NS2. The result shows that the proposed algorithm is effective.%通过对无线mesh网络的特性分析及其对路由的影响,提出一种基于预测时延的路由选择的组播路由算法,该算法通过选择从源节点到目的节点传输时延最小的路径,通过路径合并,形成组播路由树.这种路由算法具有低时延QoS保障能力,并具有局部修复能力.基于NS2对算法进行仿真,结果证明了算法的有效性.
