Internet of Vehicles (IoV) can significantly improve the driving conditions of vehicles, but the mobility characteristics of vehicles put forward higher requirements for the robustness of the IoV system. As an important component of the IoV, the deployment of RoadSide Unit (RSU) directly influences the service performance of the IoV system to vehicles, and reasonable RSU deployment can save resource costs and improve system operating efficiency. This paper proposes an RSU deployment mechanism based on the popularity of road intersections, which uses three traffic parameters, vehicle contact time, intersection connectivity, and intersection coverage capacity, as the main reference indicators. Meanwhile, an improved hotspot discovery algorithm (IHDA) is utilized to introduce inhibition distance during deployment to reduce interference between RSUs. The simulation results demonstrate that, compared with the existing typical deployment methods, this program can improve the coverage time ratio and the contacts of vehicles per trip.

基于节点流行度的路边单元部署机制

车联网（IoV）可以显着改善车辆的驾驶条件，但车辆的移动特性对车联网系统的鲁棒性提出了更高的要求。作为车联网的重要组成部分，路侧单元（RoadSide Unit，RSU）的部署直接影响车联网系统对车辆的服务性能，合理的 RSU 部署可以节省资源成本，提高系统运行效率。本文提出了一种基于道路交叉口流行度的RSU部署机制，以车辆接触时间、交叉口连通性和交叉口覆盖能力三个交通参数作为主要参考指标。同时，利用改进的热点发现算法（IHDA）在部署过程中引入抑制距离，以减少RSU之间的干扰。
