    摘要:

    车用自组网作为移动自组网在智能交通系统中的应用,有望为人们提供更安全、效率更高的旅行方式.广播协议为危险警告、协同驾驶、路况通报等交通信息的发布提供了有效途径.简要介绍了车用自组网的特点和应用分类.采用分析和比较方法,讨论各种信息广播协议的特点、性能差异和应用范围,并针对车用自组网的特点及应用需求指出未来信息广播模型的设计思想和突破方向.

    Abstract:

    As an application of mobile ad hoc networks (MANET) on Intelligent Transportation Information System, the most important goal of vehicular ad hoc networks (VANET) is to reduce the high number of accidents and fatal consequences dramatically. One of the most important factors that would contribute to the realization of this goal is the design of effective broadcast protocols. This paper introduces the characteristics and application fields of VANET briefly. Then, it discusses the characteristics, performance, and application areas with analysis and comparison of various categories of broadcast protocols in VANET. According to the characteristic of VANET and its application requirement, the paper proposes the ideas and breakthrough direction of information broadcast model design of inter-vehicle communication.
