Description:

Vehicle-to-vehicle (V2V) communication will be an essential part of Intelligent Transportation Systems. It will allow nearby vehicles to communicate without the dependence on any infrastructure or roadside equipment. Recent development in vehicle-to-vehicle (V2V) communication has increased the need of simulation to test and analyze protocols for this emerging technology. Packet level network simulators such as Network Simulator 2 (NS-2) lack a realistic V2V channel module which would allow having accurate simulation results. Measurements have shown that the V2V channel has Nakagami fading whose severity changes according to the distance separating the vehicles. This project describes an efficient method for generating a Nakagami faded envelop whose power spectrum and fading severity changes with vehicles velocity and separation. This small-scale fading envelop is used to modulate a large-scale path loss power model. The implementation uses a simple pre-computed lookup table to generate the power envelop with minimal calculations in the simulator.
