根据无线Mesh网络的结构特点,对现有的路由协议进行了分析,并针对其中一种典型的路由协议AODV延时过大的缺点进行了优化,即I—AODV。其在AODV中引入表驱动的机制,增加维护的邻居节点数目,获得更多节点的路由信息,在路由建立时达到降低网络延时的目的。最后通过仿真软件NS-2进行了模拟测试,测试结果表明,I—AODV的网络延时等网络性能明显得到了改善。

Based on the structural features of wireless Mesh networks, the paper analyses the present routing protocol and proposes I-AODV to improve the AODV routing protocol which has the disadvantage of mueh network delay. A table-driven mechanism is introduced in AODV to increase neighbor point and gets more routing information for the purpose to reduce network latency. Finally, a network simulation platform is built by using NS-2 software. Simulation experiments results show that I-AODV network algorithm has better performance than AODV such as network delay and so on.
