【摘要】：车联网是移动互联网的延伸,其中基站协作的D2D通信适用于车间交通消息的短距离无线传播。针对车辆快速移动导致的通信链路动态性,提出了一种基于可变距离的D2D连接选择方法。通过选择行车道及车间距离参数,估计D2D连接对的信道质量,推导了D2D连接选择的优先指数,并基于该优先指数建立D2D通信链路进行交通消息传播。仿真结果显示,所提方法在D2D连接的生存时间、传输效率方面得到提高,同时降低了D2D通信的中断概率,提升了车辆间通信可靠性。
[Abstract]:Vehicle networking is an extension of mobile Internet, in which D2D communication based on base station cooperation is suitable for short distance wireless transmission of workshop traffic message. A D2D connection selection method based on variable distance is proposed for the dynamic communication link caused by the rapid movement of vehicle. The channel quality of D2D connection pair is estimated by selecting lane and workshop distance parameters, and the priority index of D2D connection selection is derived. Based on this priority index, D2D communication link is established for traffic message transmission. The simulation results show that the proposed method can improve the lifetime and transmission efficiency of D2D connection, reduce the outage probability of D2D communication, and improve the reliability of inter-vehicle communication.
