Performance evaluation of Nakagami model for Vehicular communication networks in developing countries

Recently, the Intelligent Transport System (ITS) has undergone significant advances aiming at improving safety in the transportation system. One such progress has led to the introduction of Vehicular Ad hoc Network (VANET). This paper analyses the performance of the Nakagami radio propagation model, which is a realistic model to simulate real life scenarios. Furthermore, this paper examines how VANETs effectively reduce traffic congestion. Topologies and scenarios related to the Mauritian road topography have been developed and simulated on NS-2. The results obtained clearly shows that VANETs can successfully diminish the problem of traffic congestion and that the performance of the Nakagami model differs with the level of fading. This contrast in the performance of the Nakagami model is further highlighted when a difference of approximately 12% is observed between the throughputs for the different levels of fading.
