基于车队双车道V2V的VANETs网络连通性分析

Connectivity analysis of VANETs based on the platoon and double-lane-V2V network

建立了基于车队的双车道V2V网络连通性数学模型,考察了网络的连通性概率随车辆密度、车辆通信半径、车队在网络中所占比例等参数变化的关系.通过仿真计算可知,当有车队存在时能大幅提高VANETs网络的连通性.以车队的方式组织行车对车联网的网络连通性具有极大的帮助.

In this paper,we establish a mathematical model of connectivity of the double lane V2V network-based on platoon,and calculate the relationship between probability of connectivity of the network and vehicle density,radius of the vehicle communication,and the proportion of the platoon in the network.The simulation results show that the connectivity of VANETs network can be much improved when platoon exists.It is helpful to the connectivity of the network of vehicles when the vehicles in the platoon are organized.
