移动AdHoc网络多径路由协议研究

摘要

移动AdHoc网是一种分布式无线网络，路由协议是移动AdHoc网络当前研究的热点之一．该文列举了几种常见的路由协议，分析了AOMDV多径路由协议的不足，采用链路检测机制，对AOMDV协议进行了改进，提出了预警式路由协议（E-AOMDV），并通过NS2模拟软件对两种路由协议进行了模拟，通过分析得出，E—AOMDV协议在端到端延迟等性能方面略优于AOMDV协议．%Mobile Ad Hoc network is a distributed wireless network. Routing protocol is one of the hottest research areas. This paper lists some common router protocols, and analyzes the insufficient of AOMDV mul- tipath routing protocol. This study uses link detection mechanism to improve AOMDV protocol. Besides that this research also studies Early-Warning Ad Hoc Ondemand Multipath Distance Vector （E-AOMDV） protocol, and uses NS2 stimulation application to compare the key performance of those two routing protocols. The result shows that E-AOMDV protocol has better performance in the delay of end-to-end and other aspects than AOMDV protocol.
