IEEE 802.11p based physical layer simulator for Car-to-Car communication

For a well working Car-to-Car (C2C) communication system the handling of the radio channel is a challenging task. The fast changing environment as a result of a time variant behavior of the channel, and the antennas, are the two most important factors influencing the C2C transmission channel. To analyze the impact of both on the performance of such a communication system is a difficult task. A possible solution is to employ a simulation-based evaluation. In this paper a physical layer simulator, based on IEEE 802.11p, is presented. For the channel modeling a 3D ray-tracing tool including a realistic traffic model is used. Besides the simulation approach, measurements results for C2C communications are provided.
