A Multi-Hop Relay Based Routing Algorithm for Vehicular Visible Light Communication Networks

The use of visible light communications (VLC) in intelligent transportation systems is becoming highly popular. In this paper, we present a predictionbased channel gain model and propose a multi-hop relaybased routing algorithm for vehicular VLC communication networks. Using the surrogate modeling lab platform SUMO and Matlab we show that, a stationary velocity of vehicles is better suited to form a good prediction, while the proposed routing algorithm offers improved signal-to-noise ratio.
