摘　　要：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 ,路由协议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网络拓扑的动态变化、任意两个节点之间建立一个使得通信总费用和带宽消费最少的正确和有效的通信路径 .描述了设计移动 Ad Hoc网络路由协议所面临的问题以及对它们的评价 ,详细比较了七种典型无线移动 Ad Hoc网络路由协议的特性和功能 ,即 DSDV,CGSR,WRP,AODV,DSR,TORA和 ABR。Wireless Mobile Ad hoc NETworks (MANET) are termed as mobile distributed multi hop 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 research paper will provide an insight into these routing protocols and will evaluate them based on a set of fixed parameters. It presents the results of a detailed their characteristics and functionality comparing seven multi hop wireless mobile ad hoc network routing protocols that cover a range of design choices: DSDV, CGSR, WRP, AODV, DSR, TORA, and ABR. At the end of this paper, research directions and open problems in the area are also discussed.
