摘　　要：车辆自组织网络(VANET)是一种特殊动态拓扑的移动自组织网络。VANET将其中的每辆汽车变成一个移动节点,车辆在其中相互交换信息,并使用这些节点创建一个移动动态网络。VANET的目的是提供无线连接并部署各种应用程序,提高安全性和交通效率。由于VANETS中的节点具有高移动性,因此将数据包路由到最终目的节点存在很多挑战。该文总结了现有的VANET路由协议,并对它们进行分类和比较,然后列出了几种经典的路由算法,并分析了它们的特性以及优缺点。最后,通过分析车载路由协议的现状,阐述了未来车载路由协议将会遇到的困难和挑战。Vehicular Ad Hoc Network (VANET) is a kind of mobile self-organizing network with special dynamic topology.VANET turns each of these cars into a mobile node,where the vehicles exchange information with each other,and uses these nodes to create a mobile dynamic network.The purpose of VANET is to provide wireless connectivity and deploy a variety of applications that improve security and traffic efficiency.Due to the high mobility of the nodes in VANETS,there are many challenges in routing packets to the final destination node.This paper summarizes the existing VANET routing protocols,classifies and compares them,and then lists several classical routing algorithms,and analyzes their characteristics,advantages and disadvantages.Finally,by analyzing the status quo of vehicle-mounted routing protocols,the difficulties and challenges that vehicle-mounted routing protocols will encounter in the future are expounded.
