Internet of Vehicles (IoV) is one of the most promising applications of Internet of Things (IoT) in the automotive industry, which can empower moving vehicles to exchange information with neighboring cars, roadside infrastructure, remote servers, traffic control centers, and so on. IoV expects to support a wide range of vehicular services, such as road safety, path planning, infotainment, and smart parking, which will play a vital role in intelligent transportation systems (ITSs) [1] – [3] . The main enabling platforms for IoV consist of dedicated short-range communications (DSRCs)-based networks and cellular networks (C-V2X). However, these terrestrial networks alone might not be able to support the vehicular applications well in all the cases and scenarios, due to the issues of limited coverage and capacity, as well as costly deployment.

车联网 (IoV) 是物联网 (IoT) 在汽车行业最有前景的应用之一，它可以使移动车辆与相邻汽车、路边基础设施、远程服务器、交通控制中心等交换信息. IoV 预计将支持广泛的车辆服务，例如道路安全、路径规划、信息娱乐和智能停车，这将在智能交通系统 (ITS) 中发挥至关重要的作用[1] – [3] . IoV 的主要支持平台包括基于专用短程通信 (DSRC) 的网络和蜂窝网络 (C-V2X)。然而，由于覆盖和容量有限以及部署成本高的问题，仅这些地面网络可能无法在所有情况和场景下很好地支持车载应用。
