In different this paper we present the performance evaluation study of a simple broadcast data dissemination technique in new emerging Vehicular Ad hoc Networks (VANETs). Differently from the traditional Mobile Ad hoc NETworks (MANETs), VANETs require particular routing protocols, due to the high dynamism of the network topology, and to different traffic and mobility patterns. For safety and emergency message applications, broadcast data dissemination is an important key factor in VANETs. However, the design of optimal deployment of relay nodes in different network scenarios allows to enhance system performance. At this aim, this work analyzes vehicular network performances in terms of throughput and delays, for different traffic scenarios, exploiting both inter-vehicular communications, as well as the availability of fixed network infrastructure.
