车联网体系结构及感知层关键技术研究

Architecture and Key Technologies for Internet of Vehicles

车联网被认为是物联网中最能够率先突破应用领域的一个重要分支,是目前一个研究热点。本文基于物联网(IoT)、智能交通系统(ITS)及信息网络已有研究成果,提出并描述了车联网(IoV)的基本概念和体系结构,并对当前的标准化研究现状进行了介绍。在此基础上,本文重点分析了车联网的架构、通信模式、主要功能、应用领域及技术难点,并以IEEE 802.11p标准和IEEE 1609协议栈为参考,对物理层、介质访问控制层和网络层的关键技术、主要协议和通信标准进行了综合讨论。

Internet of vehicles （IoV） is considered to be an important branch of internet of things （loT）, is the first application breakthrough in the IoT＇s area, is also a hot research topic for many years. Based on the research production of IoT, intelligent transportation systems （ITS） and information network, the basic concept and architecture of IoV were described. At the same time, the research status of IoV was introduced. On this basis, the vehicular network architecture, communication mode, main function, application area and the technical difficulties were analyzed. Finally, consulted the IEEE 802.11p standard and the IEEE 1609 protocol stacks, the key technologies, protocols and communication standards of IoV＇s physical layer, MAC layer and the network layer were discussed.
