论文摘要
在这项工作中，我们展示了采用光学智能反射表面（O-IR）的潜在好处，以改善车辆可见光通信（V-VLC）系统的安全消息传播（尤其是在道路交叉点）。建筑物，路边结构，招牌和其他障碍通常会阻碍城市十字路口的车辆之间的视线（LOS）通信。我们建议在道路交叉路口使用O-IRS来提高通信链接的可靠性。我们将拟议方案的性能与基线方案（如光继电器和非视线（NLOS）道路反射（NRR）辅助车辆到车辆（V2V）通信等基线场景进行了比较。从获得的结果中可以看出，与基线方案相比，O-IRS提供了相当大的性能提高。特别是，与光学继电器辅助V-VLC系统相比，O-IR可以实现更长的通信范围，同时确保所需的服务质量（QOS）。
In this work, we showcase the potential benefit of employing optical intelligent reflecting surfaces (O-IRS) for improving safety message dissemination for vehicular visible light communication (V-VLC) systems particularly at the road intersections. Buildings, roadside structures, signboards, and other impediments commonly hinder line-of-sight (LoS) communication between vehicles at urban crossroads scenarios. We propose using O-IRS at road intersection to improve the communication link's reliability. We compare the performance of proposed scheme with baseline scenarios such as optical relay and non line-of-sight (NLOS) road reflection (NRR) aided vehicle-to-vehicle (V2V) communication. From obtained results, it has been shown that O-IRS offers considerable performance enhancement as compared to the baseline scenarios. In particular, O-IRS can achieve longer communication range as compared to the optical relay aided V-VLC systems while ensuring desired quality-of-service (QoS).
