Vehicle-to-vehicle communication: End-to-end performance evaluation in dense propagation environments

In this paper, an analytical methodology for the performance evaluation and dimensioning of end-to-end transmissions in Vehicle-to-Vehicle (V2V) communication systems is presented. The proposed methodology is focused on dense propagation environments such as urban roads and Manhattan grid topologies with dense infrastructure, tunnels and large parking garages where both large and small scale fading effects strongly determine the V2V communication system´s performance. In our analysis, we calculate the aggregated bit error probability through multi-hop transmissions, considering the vehicles´ spatial distribution under realistic propagation and well accepted channel models. The Nakagami-m channel model is considered for the small scale fading effects and a composite channel model appropriate for the complex environments is also employed. The proposed model may be used for the accurate evaluation of vehicular networks dedicated for safety reasons and many intelligent transportation applications.
