Impact of Weather Conditions and Interference on the Performance of VLC based V2V Communication

This works analyses the performance of Visible Light Communication (VLC) based Vehicular-to-Vehicular (V2V) Communication under different weather conditions viz. dense fog, light fog, wet snow, dry snow, rain etc. while considering the effect of interference from nearby vehicle. The performance has been evaluated by obtaining both quantitative as well as qualitative results. Through the obtained results, it has been shown that different weather conditions significantly impact the performance of VLC based V2V as compared to normal atmospheric conditions. It can be also inferred that interference from nearby vehicle and unfavourable weather conditions adversely impacts the Signal-to-Interference plus Noise ratio (SINR) for the VLC link which consequently reduces the maximum achievable communication-distance between the vehicles.
