The influences of communication models on the simulated effectiveness of V2X applications

In this paper, we aim to evaluate the influences of different propagation models on the results of V2X simulations. First, we shall analyse how the models Free Space Propagation, Rayleigh Fading, and Rice Fading in synthetic scenarios with and without background communication influence the simulation of the communication in general. After that, we will investigate the impact of the models on the simulated behaviour of a V2X traffic efficiency application in a real inner city scenario. Our results will show that the selection of the propagation model affects the number of delivered messages, but exerts no significant influences on the simulated effectiveness of a V2X traffic efficiency application in urban areas. Under those circumstances, a simplified propagation model is sufficient.
