移动自主网络多路径路由技术研究进展

MANET具有许多与传统有线网络截然不同的特性，包括移动性、有限的带宽资源、易变的网络拓扑等，因而就需要一种新的路由协议来解决这些缺点。大多数已提出的MANET路由协议没有考虑公平性，它们倾向于把重的负载分布到源一目的对的路径最短的主机上。结果，超重负载的主机会迅速耗尽能源，这将导致网络分离，应用会话失败。为解决
决这个问题，众多专家学者提出用多路径的方法来承担路由任务。本文回顾了MANET多路径路由技术的研究进展，并对有关路由协议进行了评述，比较了各自的贡献和不足；最后对路由协议研究的发展方向进行了展望。

A Review of Routing Protocols for Mobile Ad Hoc Networks

There are significant differences between wire networks and MANETs.MANETs have nodes with high mobility,limited bandwidth resources,and variable topology.Therefore,there is a need for new routing protocols,which solves all these drawbacks.Most routing protocols for MANETs do not take fairness into account.They tend to have a heavy burden on the hosts along the shortest path from a source to a destination.As a result,heavily loaded hosts may deplete power energy quickly,which will lead to network disconnections and failure of application sessions.There have been some methods of multipath routing to solve the question.In this paper,the progress of the multipath routing technique is surveyed,and various routing protocols are described and evaluated,which cover most types of multipath routing protocols,and then provide a comparison and discussion of their respective merits and drawbacks.Finally,the future research directions are outlined.
