摘要
移动边缘计算(MEC)技术将IT服务环境与云计算技术在网络边缘结合以提高边缘网络的计算和存储能力,减少网络操作和服务交付时延;应用MEC的车载网络可以满足车辆对服务延时和通信可靠性的严格要求,提升车辆用户的服务质量(Qo S)。对移动边缘计算在车载网中的应用进行分析研究,首先概述MEC的基本概念及架构、典型应用场景;然后介绍MEC在车载网中的应用、基于软件定义网络(SDN)的车载网MEC研究现状以及车载网MEC应用实例;最后给出了车载网中部署MEC所要面临的问题和挑战,并对该领域未来的研究方向进行了展望。
Mobile edge computing( MEC) technology combined IT service environments and cloud computing technologies at the edge of the network to improve the computing and storage capabilities of edge networks while reducing network operations and service delivery delays. Vehicular network integrating MEC could meet the strict requirements of vehicle service delay and communication reliability,as well as improve the quality of service for vehicle users. This paper studied and analyzed MEC applications in vehicular networks. Firstly,it provided a brief on the basic concept and architecture of MEC,and its typical application scenarios. Thereafter,it described a comprehensive survey of relevant research in the area of MEC-based vehicular network along with a focus on the current SDN-related works on MEC-based vehicular network,as well as several use cases. Finally,this paper discussed the main problems and challenges to deploy MEC in vehicular network,and analyzed the future research directions on these areas.
