摘要:

智能交通系统的发展对现有的车载网络提出了更高的要求。例如,为了确保车辆之间的安全通信,车辆网络需要低延迟、高连接性和高数据率。为了满足这些要求,用于车辆网络的5G通信系统应该相应地改进。本文提出了一种5G车载网络的通信方案,在该方案中,移动接入点部署在车辆上,以方便车辆用户的访问。此外,相邻的车载移动接入点可以通过联合发送和接收与车辆用户协作通信。以这种方式,车辆用户以无小区方式与一个或多个未指定的协作接入点通信,而不是与单个接入点相关联。为了管理这种无小区网络,采用本地移动软件定义的云来执行传输和调度管理。仿真结果表明,该方案在显著降低时延的同时,提高了车联网的连通性,可作为5G车联网解决方案的一个研究方向。

英文摘要:

The development of intelligent transportation systems raises many requirements to the current vehicular networks. For instance, to ensure secure communications between vehicles, low latency, high connectivity and high data rate are required for vehicular networks. To meet such requirements, the 5G communication systems for vehicular networks should be improved accordingly. This article proposes a communication scheme for 5G vehicular networks, in which moving access points are deployed on vehicles to facilitate the access of vehicle users. Moreover, the adjacent vehicle-installed moving access points may cooperatively communicate with the vehicle users by joint transmissions and receptions. In this way, the vehicle users communicate with one or more unspecified cooperative access points in a cell-less manner instead of being associated to a single access point. To manage such cell-less networks, local moving software-defined cloudlets are adopted to perform transmission and scheduling management. Simulation results show that the proposed scheme significantly reduces the latency, while improving the connectivity of the vehicular networks, and can be considered as a research direction for the solution to 5G vehicular networks.
