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. |
