A Channel Model for VANET Simulation System

Vehicular Ad Hoc Network (VANET) is the key technology of Vehicle Infrastructure Integration (VII). Microscopic simulation is an effective means for VANET research, and radio channel model is the basis of VANET simulation. In this paper, radio wave propagation models, such as reflection and diffraction models, are combined to develop a VANET channel model, and the model is introduced into VANET simulation system. Path loss and received power under different traffic flow are analysed using our VANET simulation system. The simulation results are consistent with the real situations of Vehicle-to-Vehicle (V2V) communication.
