摘　　要：随着无线通信技术的快速发展和车辆在日常生活中的不断普及,车辆传感器网络作为新一代的网络技术越来越被重视。文章基于无线车辆传感器网络的基本概念和体系结构,讨论了车辆传感器网络与传统无线传感器网络的主要区别,以及由此引入的各种设计上的挑战。对车辆传感器网络中的关键技术,包括媒体访问控制(MAC)协议、路由协议和移动模型,文章进行了研讨,并介绍了世界上已建立的车辆传感器网络试验床。文章还介绍了行车安全、城市监控、路况监测、交通流量监测等几种典型的车辆传感器网络的应用。With the rapid development of wireless communication technology and the widespread adoption of vehicles in daily life, Vehicular Sensor Network （VSN） technology, as a new paradigm of computer networking, has attracted increasing attention from both industry and academy. Based on the basic concepts of VSN and its architecture, this paper discusses the key differences between VSNs and traditional Wireless Sensor Networks （WSNs）. It also introduces a variety of design challenges. In addition, the paper presents several existing studies for key enabling technologies, such as MAC protocol, routing algorithm and mobility model. Two prototypes of VSNs are then briefly described. Finally, several typical applications including driving safety, urban monitoring, road surface monitoring, and traffic monitoring are introduced.
