车载自组织网络通信协议

A comprehensive overview on vehicular ad-hoc network

车载自组织网络(VANET)被认为是未来智能交通系统(ITS)的重要组成部分,可有效提高行车效率、安全性和舒适性。VANET属于移动自组织网络(MANET),不依赖固定设施,其节点高速移动、网络拓扑变化频繁,具有与MANET不同的构架、特征、应用和挑战。本文综述了VANET网络构架、通信协议、建模与仿真、信息管理和云计算等方面的研究进展,展望了未来的发展方向。

Vehicular ad-hoc network（VANET） is considered an integral part of the future intelligent transportation system（ITS） that has the potential in improving traffic efficiency, road safety and traveler＇s comfort. VANET is a subset of mobile ad-hoc network（MANET） and does not depend on any fixed infrastructure. The nodes are highly mobile and the network topology changes rapidly. It differs from MANET in terms of architecture, characteristic, application and challenge. In this paper, the latest research progress in VANET network architecture, communication protocols, modeling and simulation, information management and cloud computing is surveyed; the research methods are briefly discussed; and the directions for future research and development are also provided.
