对AODV路由协议中的断链问题进行了分析和仿真,提出了对其进行优化的方案并给出具体实现。优化方案使用了本地的反向路由重建方法,通过广播一个链路修复消息同时完成了路由查找和路由建立的任务。与传统的路由重建方式相比,可以节省在重建路由时引入的时延,并在一定程度上减少了路由重建的额外开销,以更好地适应自组网的应用环境。
AODV routing protocol in the chain scission problems were analyzed and simulated, put forward to optimize the program and give the concrete realization. The optimization scheme uses a local reverse route reconstruction method to perform the task of route discovery and route establishment by broadcasting a link repair message. Compared with the traditional route rebuilding method, the delay introduced in rerouting the route can be saved, and the additional cost of route rebuilding can be reduced to a certain extent so as to better adapt to the application environment of the ad hoc network.
