摘要：簡要介紹了移動Ad Hoc網絡和AODV路由協議，并在對AODV路由協議進行了研究的基礎上針對AODV路由協議的不足之處提出了一種優化方法。此方法比較了路由節點的平均速度，選取平均速度小的路由為備用路由。當主路由失效后，就啟動備用路由。通過NS-2對改進的路由協議與AODV路由協議的仿真模擬，比較了平均端到端時延、丟包率、網絡吞吐量這三個參數，驗證了修改后的路由協議減少了網絡開銷，能更好的提高網絡的性能。

ABSTRACT: This paper introduced the Ad Hoc network and AODV routing protocol and proposed an optimization method based on studying its inadequacies. This method compared the average speed of the routing nodes and selected the minimum average speed routing as an alternate routing. When the primary route fails, start the alternative route. The average delay, drop ratio and network throughput were compared by simulating new routing protocol and the AODV routing protocol through NS-2. Results indicated that the optimized protocol decreased the expense of network and showed better performance than AODV routing protocol.
Key Words：AODV routing protocol ; alternate routing ; speed of the node ; NS-2
