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。
Internet of vehicles is an extension of the mobile network.Traffic messages can be disseminated in a short range by D2D communication technology under the base station controller.For decreasing the dynamics of the com-munication link due to rapid movement
a new D2D connection selection scheme based on variable distance between vehicles was proposed.By selecting the traffic lane and workshop distance parameters
the channel quality between D2D pairs was estimated
the priority index of D2D connection selection was deduced
and the D2D communication link was established based on the priority index for traffic message propagation.The simulation results show that the proposed method has an improvement in the survivability and transmission efficiency of D2D connection.At the same time
the reliability of traffic message dissemination in short range was improved by decreasing the outage probability of D2D communication.
