摘　　要：基于队列的驾驶模式能够有效提高道路的通行能力和能源效率,在此基础上,研究了基于队列的车辆网络在有窃听者存在下的无线连接性能,推导出队列内、队列外和整个网络的安全连通概率,以分别描述单个队列、两个队列和所有队列组成的网络。仿真结果表明,影响连接性能的系统参数包括传输范围、窃听者数量和车辆密度,且存在最优车辆密度使安全连接性能达到最佳。Platoon-based driving has been proved to effectively improve road capacity and energy efficiency.On this basis,this paper investigates wireless connectivity of platoon-based vehicular networks with the presence of eavesdroppers.Three types of secure connectivity probability,intra-platoon secure connectivity probability,extro-platoon secure connectivity probability and net‐work secure connectivity probability,are defined and derived to respectively characterize the network constituted by a single pla‐toon,a double platoon and multiple platoons.Simulation results show that system parameters affecting connectivity performance include transmission range,number of eavesdroppers and vehicle density.Particularly,secure connectivity probabilities are maxi‐mized by an optimal vehicle density.
