无线移动Ad Hoc网络的路由技术研究

Research of the Routing Techniques in Wireless Mobile Ad Hoc Networks

无线移动Ad Hoc网络(MANET)作为可移动分布式多跳无线网络,没有预先确定的网络拓扑或网络基础设施以及集中控制。 为了在如此的网络中促进通信,路由技术主要用于在节点之间发现路径。 Ad Hoc网络路由协议的主要目的是在网络拓扑的动态变化下任意两个节点之间建立一个使得通信总费用和带宽耗费最少的正确和有效的通信路径。本文论述无线Ad Hoc网络的特性、问题和技术,并通过不同的标准对存在的一些路由协议进行分类和比较.

Wireless mobile Ad Hoc networks (MANET) are termed as mobile distributed multihop wireless networks without predetermined topology (preexisting fixed infrastructure) or central control. In order to facilitate communication in such a network, a routing protocol is used to discover routes between nodes. The main aim of any such ad-hoc network routing protocol is to meet the challenges of the dynamically changing topology and establish a correct and an efficient communication path between any two nodes with minimum routing overhead and bandwidth consumption. This paper has presented a comprehensive review for routing features, issues and techniques in wirel- ess ad hoc networks. For seven typical existing routing protocols, it has compared their properties according to different criteria, and categorize them according to their routing strategies and relationships.
