摘　　要：无线Ad Hoc网络由于无固定基础设施,以及自我组织、分布管理、动态拓扑、多跳通信等特点成为近年研究的热点.地理位置路由是Ad Hoc网络中有别于基于拓扑路由的一种路由方式.它能利用节点的位置信息来指导路由发现,路由维护和包的转发,从而提高路由的效率.Ad Hoc网络包括限制性泛洪路由和分层路由2种类型.介绍了各种Ad Hoc网络路由协议,讨论了Ad Hoc网络的地理位置路由机制,分析了现有的地理位置路由协议.Recently, mobile wireless Ad Hoc network has been the research focus as its characteristics of no pre-existing infrastructure, self organization, distribute management, dynamic topological and multi hop communication,etc. Geographic routing using nodes location is a routing mechanism which is different from the topology based routing in Ad Hoc networks and it can use nodes＂ location infdrmation to guide the route discovery, route maintenance and the packets forwarding. Two catalogues of routing algorithms include the restricted flooding routing and hierarchical routing. An overview of Ad Hoc routing protocols are presented in his paper. And then, the geographic routing of mobile Ad Hoc networks is discussed. Finally,the existing Geographic routing protocols are introduced and analyzed.
