The impact of mobility on the performance of V2X communication

The performance evaluation of the Vehicle to Vehicle and Vehicle to Infrastructure V2X communication system is an important step before its integration into vehicles and its probable real deployment. In this paper, the physical layer PHY of the upcoming vehicular communication standard IEEE 802.11p is an issue of our study. A near realistic IEEE.802.11p PHY model, with all the associated phenomena, is implemented in V2X situation through different scenarios. The series of simulation results carried out perform data exchange between high-speed vehicles as well as the vehicles and the roadside infrastructure over Rician channel model. We underlined several and important propagation channel parameters which affect both the physical layer network performance and the quality of transmission. The Bit Error Rate BER versus Signal to Noise Ratio (SNR) of all coding rates is used to evaluate the performance of the communication systems.
