摘　　要：随着车载自组网络(VANETs)应用的不断深入,有关VANETs技术研究已成为众多学者关注的热点。由于VANETs节点的高速移动、不稳定的无线信道等显著特点,导致网络拓扑结构变化快、节点通信呈机会性、路径可用的持续时间短,因此,设计稳定可靠的消息路由方案成为VANETs应用的核心问题。阐述了路由协议研究的重要性,并对VANETs的各种路由协议的进行了比较,分析各自优缺点,同时将现有的VANETs路由协议根据其性质分为五类,并研究了每类协议的特点。最后分析了VANETs的未来研究方向。With the deepening of vehicle Ad Hoc networks（ VANETs） application,research about VANETs technology has become hot topic focused by many scholars.The network topology structure change quickly and the communication between nodes is opportunistic,available duration time of path is short due to the high-speed mobility of nodes and unstable wireless channel,therefore,the design of stable and reliable routing scheme has become the core issue of VANETs application.Importance of research on routing protocol in VANETs is addressed,moreover,the merits and faults of existing routing are discussed and compared.Existing routing protocols in VANETs is classified into five,and each characteristic of each category protocol is analyzed.Finally, research directions of VANETs in further is analyzed.
