车辆自组织网络

Vehicular Ad Hoc Networks

本文阐述了车辆自组织网络(VANET)的基本概念,指出了VANET与移动自组织网络(MANET)、无线传感器网络(WSN)等系统之间的异同,分析了VANET的体系结构及其协议栈层次,并对车辆网络的典型应用进行了分类,介绍了与VANET相关的研究机构、主要技术标准以及欧洲、美国和日本在该领域的最新研究计划和研究项目,最后综述了频谱分配、信道接入、信息分发和系统建模等关键支撑技术。

This paper describes the concept of vehicular ad hoc networks (VANET), and indicates the similarities and differences with mobile ad hoc networks (MANET) and wireless sensor networks (WSN). The system architecture for VANET is outlined, the communication protocol stacks are investigated, and the potential applications are explored. The VANET-related consortia, standards, and projects around the globe are presented. The enabling technologies, such as spectrum allocation, media access, information dissemination, and system modeling, for the realization of vehicular networks are also reviewed.
