Abstract
This paper proposes an outdoor vehicle-to-vehicle visible light communication (VVLC) channel model. Due to the lack of a realistic channel model that takes the vehicles mobility and the light propagation nature into consideration, we propose a regular-shaped geometry based stochastic channel model (RSGBSM). Particularly, we suggest the ellipse shape to describe the line of sight (LOS) and the reflection components of the VVLC. This approach offers flexibility to describe vehicles locations, speed and direction as well as stationary and non-stationary reflectors which are changing rapidly and continuously. The simulation results demonstrate that the LOS channel component is more affected by the direction of motion than the reflection component, whereas the reflection component is more affected by the relative speed of the vehicles.
