Abstract: In order to choose a route with high reliability and avoid using high mobility nodes in the process of route discovery，a revised routing algorithm based on AODV is proposed in this paper.The nodes’ mobility information is taken into account fully in the algorithm.Compared to AODV，the revised protocol can find routes that are more reliable and reduce the possibility of route breakage.Results of the computer simulation show that the revised method has a better performance of packet delivery ratio and end to end delay.

摘要： 为了在路由请求时避免使用相对移动性很高的节点，在路由应答时选取更可靠的路由，提出一种AODV路由协议改进算法，该算法充分利用Ad hoc网络节点的移动性信息，与AODV相比，改进后的协议可发现更稳定的路径，并明显降低路径断裂的概率，且协议的延时小，包投递率高。仿真结果验证结论的正确性。
