Channel Modeling and Analysis for Radio Wave Propagation in Vehicular Ad Hoc Network

VANET is the basic technology of Vehicle Infrastructure Integration (VII). Vehicular Ad Hoc Network (VANET) is the network that is connecting a vehicle to the infrastructure (V2I) and vehicle to vehicle (V2V) via wireless manner to convey the information between them. Therefore analyzing influence such channels on the VANET system performance is crucial. This paper is conducted to model and analyze the channel for radio wave propagation with considering free space, two ray ground reflection and single knife edge diffraction. The received power, path loss and effect state of the communication sides whether is in moving stable are discussed. The direction of moving of the vehicles and location of obstacles are also taken into account for calculating the received power and path loss.
