摘要
车联网(Internet of Vehicles,Io V)被认为是物联网中最有可能率先突破应用的一个重要分支,成为目前研究的重点和热点.其中,车辆节点的定位和位置感知技术是车联网的技术核心,不仅关系到车辆行驶过程中的安全,而且影响着车联网的发展前景.首先,提出了车联网定位和位置感知的评价标准,介绍了无线定位测距技术的实现原理和方法.在此基础上,重点阐述了车联网的定位和位置感知技术,讨论了相关算法以及在车联网中的应用特点.最后,在综合分析了现有研究成果的同时,对未来的研究方向进行了展望.
Internet of Vehicles（ IoV） has been considered to be an important branch which is most likely the first breakthrough in the application of Internet of Things（ IoT）,and has become the focal point of research. Among them,the localization and the location-aware of vehicles are key technologies of the IoV. These two technologies not only is related to vehicle security,but also affected the prospects for the development of IoV. First,the standards of evaluation on localization and nodes location-aware of IoV have been presented,and the principle and method of wireless location based on range-based have been introduced. On this basis,localization and nodes location-aware technologies of IoV have been focused,and the algorithm and applications in IoV have been discussed. Finally,in the comprehensive analysis of existing research results at the same time,we conclude the paper by elaborating the future research directions on the IoV.
