摘　　要：当前Ad Hoc路由协议一般都是单路径协议。然而由于多路径路由方式可以大大减少路由开销,提高数据传输率,减少网络拥塞,是未来Ad Hoc网络路由的主要方式。为此分析讨论了几种典型的多路径路由协议,并对这些多路径协议进行评价,对其性能进行比较,讨论了多路径协议在QoS(Quality of Service)、能源和安全方面的应用,指出未来多路径研究的关键问题。In mobile Ad Hoc networks, routing becomes a challenge task due to the nodes mobility and topology changeability. At present Ad Hoc network routing protocol is unipath. However, muhipath routing can reduce routine overhead and Improve delivery ratio. As a result, it can avoid some network congestion. In this paper we introduce some typical muhipath routing protocols, evaluate these muhipath protocols and compare their performance. We also introduce some uhipath protocols, which have better performance in QoS （Quality of Service） , energy and security In the end, we point out some key problems for future research.
