由于在车对车V2V场景中天线非常低，通信链路很容易被其他车辆阻挡。现有的大多数V2V信道模型都忽略了其他车辆的遮挡效应，因此在系统性能评估中也忽略了它。通过将信道状态转换与基于测量的双斜率路径损耗模型相结合，提出了一种基于障碍物的模型，用于V2V高速公路场景，以捕捉其他车辆作为移动障碍物时无线信道的动态特性。主要研究了无线环境和业务流对链路连通性的联合影响。给出了阻塞概率，并评估了与连通性相关的指标：车辆间连通性概率和链路持续时间。所有的分析结果都在基于测量的路径损耗模型下进行了大量的仿真验证，并与现有的模型进行了比较。
Since the antennas are very low in vehicle-to-vehicle V2V scenarios, the communication link is easily blocked by other vehicles. The shadowing effect caused by other vehicles has been ignored in most of the existing V2V channel models, and it is thus neglected in the system performance evaluation. By incorporating channel state transition with a measurement-based dual-slope path loss model, an obstacle-based model is presented in this paper for the V2V highway scenarios to capture the dynamic characteristics of radio channels, in the presence of other vehicles as moving obstacles. The joint effects of the radio environment and traffic flow on link connectivity are mainly investigated. The obstruction probability is represented, and the connectivity-related metrics are evaluated: inter-vehicle connectivity probability and link duration. All the analytical results are validated by extensive simulations under the measurement-based path loss model, and are also compared to the existing models.
