摘要： 针对移动Ad Hoc网络中现有AODV路由协议中存在的长路由现象，提出一种路径优化策略，以缩短路由长度，避免优化过程中不必要的通信中断，实现无缝切换。通过NS2仿真证明，在现有带宽和反应时间内可以提高网络的性能，没有增加太多额外的资源耗费，端到端延迟和分组传输率等性能都有提高。

Abstract: This paper presents a method of Path Optimizing Strategy(POS) to solve the phenomenon of long routing, which is existing in Mobile Ad Hoc Network(MANET) of AODV routing protocol. The results of NS2 simulation prove that POS improves the network performance without increasing the additional resources cost too much in the existing bandwidth and response time, such as end-to-end delay and packet transmission rate.

Key words: Mobile Ad Hoc Network(MANET), long routing, Path Optimizing Strategy(POS)
