Abstract

The common underlying assumption in vehicle-to-vehicle (V2V) visible light communication (VLC) is that connected vehicles travel serially, so a line-of-sight (LoS) link is always maintained. However, in scenarios where in-parallel vehicles communicate to avoid crashes, LoS link is usually absent. In this letter, we utilize optical reflecting intelligent surfaces (RISs) to relax the LoS constraint. Based on realistic V2V-VLC channel modeling, we derive novel closed-form expression for the number of RIS elements required to achieve a target energy/spectral efficiency in RIS-aided V2V-VLC system. We further investigate the impact of transceiver, system, and environment parameters on the system performance.
