PERFORMANCE ANALYSIS OF MULTI-HOP VEHICULAR VLC NETWORKS

Abstract

Vehicular Visible Light Communication (V2LC) is a promising technology that enables our dream of having automated vehicles. V2LC helps vehicles to share data and information to run properly on road. In our paper, we have analyzed the performance of V2LC by using a simplified road model that contains only one way and one lane. Vehicles are installed with two light-emitting diodes (LED) headlamps and a photodetector (PD) that are transmitters and a receiver respectively. BER is evaluated while changing the distance between two vehicles. Moreover, we have considered how the attached position of PD and the horizontal gap between two vehicles affect BER. Finally, multi-hop among vehicles in the network is taken into account to have a clear view of the whole transmission performance.
