Quality of service is negatively impacted by the attenuation of the communication signal over the transmission distance. The attenuation phenomena can be modelled using different fading models; Nakagami model is regarded as the most realistic one. Attenuation in VANET is more challenging since it depends also on vehicle’s length and node density. The main purpose of this paper is to evaluate the performances of Ad hoc On-demand Distance Vector, Dynamic destination-Sequenced Distance Vector and Optimized Link State Routing protocols. A real map from an urban zone has been used. The map has been prepared using the simulator of urban mobility (SUMO) for the network simulator 3 (ns-3). Results show that Ad hoc On-demand Distance Vector Routing Protocol outperforms the others being the most resistant to fading phenomena.
