摘要
基于地理位置的路由协议因其对动态拓扑的高适应能力已成为车载自组织网(Vehicular Ad Hoc Network,VANET)的主导路由协议。首先,介绍基于地理位置的路由协议的基本思想,描述几种经典的基于地理位置的单播和多播路由协议算法。其次,分析VANET的特点,基于此对VANET环境中基于地理位置的单播和多播路由协议进行分析总结。再次,介绍欧洲电信标准化协会提出的面向VANET的基于地理位置路由的协议标准GeoNetworking的基本实现框架。最后,对VANET中基于地理位置的路由协议存在的问题进行分析总结,指出未来的研究方向及挑战。
Geographic routing protocol has become the dominant routing protocol for vehichlarAd Hoc network because of its high adaptability to dynamic topology.Firstly,this paper introduces the definition of geographic routing protocol and some basic algorithms of geographic routing protocols and Geocast.Secondly,it analyzes the characteristics of VANET environment.Based on this,the geographic routing protocol and Geocast in VANET environment are analyzed.Thirdly,it introduces the basic implementation framework of GeoNetworking,a protocol standard based on geographic routing for VANET,proposed by European Telecommunication Standardization Association.Finally,the problems of geographic routing protocols in VANET are analyzed and summarized,and the research directions are pointed out.
