针对传统AODV路由协议在选择路径时仅仅只以最短路径和最快响应作为度量准则而导致得到的路径并非最优问题,分析了按需路由协议AODV的基本原理,研究并提出了一种基于最大路由速率的AODV路由协议的优化方案,通过计算并比较每条路由中的传输速率,选择出速率最大的一条路由。NS2仿真实验表明改进的路由可以解决最短路径算法带来的吞吐量低、路由不稳定等问题,较好地改善了协议性能。
In view of the traditional AODV routing protocol which only uses the shortest path and the fastest response as the metric when selecting a path, the resulting path is not the optimal one. The basic principle of AODV is analyzed and a new algorithm based on the largest Routing AODV routing protocol optimization program, by calculating and comparing the transmission rate of each route, select the one with the highest rate. NS2 simulation results show that the improved routing can solve the problems of low throughput and unstable routing caused by the shortest path algorithm, which improves the protocol performance.
