【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。
[Abstract]:With the development of vehicle-mounted ad hoc network (VANET) application, the research on VANETs technology has become a hot topic for many scholars. Because of the high-speed movement of VANETs nodes. The unstable wireless channel and other remarkable characteristics lead to the rapid change of network topology, the node communication is opportunistic, the duration of path available is short, so. Designing stable and reliable message routing scheme has become the core problem of VANETs application. This paper expounds the importance of the research of routing protocols, and compares various routing protocols of VANETs. At the same time, the existing VANETs routing protocols are divided into five categories according to their properties, and the characteristics of each kind of protocols are studied. Finally, the future research direction of VANETs is analyzed.
