【摘要】：车载通信网络是一种高速移动的自组织网络.车辆快速移动导致的网络拓扑结构快速改变和网络的频繁断开,使多跳通信成为挑战,因此车辆的连通性对于研究多跳通信至关重要.为此,从车间时距出发,在合理分析道路交通的情况下,假设车间时距服从爱尔朗分布,速度服从正态分布,从而分析出单位时间内车辆到达数目与平均车辆密度的关系,以及通信距离与车辆连通性之间的关系,建立了一种基于车间时距的车载通信网络连通模型.仿真结果表明,单位时间内车辆到达数目越多,平均车辆密度越大,车辆连通性越好,由此得到车辆的最佳通信距离,从而为今后研究车载通信网络中的数据传输提供一个网络连通模型.
[Abstract]:Vehicle-borne communication network is a high-speed mobile self-organization network. The rapid change of the network topology and the frequent disconnection of the network caused by the rapid movement of vehicles make the multi-hop communication become a challenge, so the connectivity of vehicles is very important to the study of multi-hop communication. Therefore, based on the workshop time distance, under the condition of reasonable analysis of road traffic, assuming that workshop time clothes are distributed from Allan and speed suits from normal distribution, the relationship between the number of vehicle arrival and the average vehicle density per unit time is analyzed. Based on the relationship between communication distance and vehicle connectivity, a vehicle communication network connectivity model based on workshop time distance is established. The simulation results show that the more the number of vehicle arrival per unit time, the greater the average vehicle density, the better the vehicle connectivity, and the better the vehicle communication distance. Thus, it provides a network connectivity model for the future study of data transmission in vehicular communication networks.
