ABSTRACT

Since the safety on roads has become a main concern for both governments and car manufacturers in the last twenty years, number of applications into the domain of vehicular communication is proposed. Vehicular Ad hoc Networks, or VANETs, fall in this category. In this paper we propose an agent based simulation model for warning messages dissemination to study the impact of self-pruning broadcast algorithm on the dissemination of warning messages between vehicles. The results are then compared to those provided by the basic simple flooding broadcast algorithm. Simulation results show that among the key factors affecting warning messages dissemination are: (i) the transmission range, (ii) the density of vehicles in the road, and (iii) the selected broadcasting method.
