研究了车辆网络中的连通性问题，重点研究了车辆在单向公路上的双向连通性问题，该公路具有一个入口和一个出口，入口和出口将道路分为两段，车辆到达服从泊松过程.在入口和出口处，车辆可以进入或离开道路，或者通过入口和出口行驶。建立了道路上行驶车辆连通概率的分析模型。分析模型考虑了车辆到达率、移动速度、车辆通过出入口的概率等影响连通性概率的参数，并考虑了两种出入口场景：一种是没有部署路侧单元（RSU），另一种是部署了一个RSU。通过仿真结果验证了该分析模型的合理性，并基于推导的分析模型研究了不同参数对连通概率的影响。
This paper studies the network connectivity problem in a vehicular network and focuses on the two-way connectivity of vehicles moving on a one-way highway road with one entry and exit.The entry and exit separates the road into two segments, where vehicle arrivals follow a Poisson process. At the entry and exit, a vehicle may enter or exit from the road, or drive through the entry and exit. A connectivity analytical model is derived for analyzing.the connectivity probability of vehicles moving on the road. The analytical model takes into account several parameters that may affect the connectivity probability, including a vehicle’s arrival rate and moving speed as well as the probability that a vehicle drives through the entry and exit.Moreover, it considers two entry and exit scenarios: one with no roadside unit (RSU) deployed, and the other with one RSU deployed. The analytical model is justified through simulation results and the impacts of different parameters on the connectivity probability are investigated based on the derived analytical model.
