Performance analysis of Multihop connectivity in VANET

This paper investigates the performance of Multihop connectivity for inter-vehicle communication (IVC) systems in Vehicular Ad Hoc NETwork (VANET). The hop path between two or more vehicles is dedicated when a broadcast signaling for initiation connectivity is successfully guaranteed. In addition, the performance of vehicular connectivity is not only based on maximum transmission range, but also based on the optimal distance headway. A new analytical model is proposed in order to determine the failure probability of connectivity based on distance headway, false initiation connectivity probability and broadcast signaling delay. Also, the successful probability of message hopping and outage connectivity probability are provided in Multihop vehicular ad hoc networks. The numerical results demonstrate the metrics performance of false and failure connectivity probability in terms of physical characteristics of the roadway, vehicular velocity, traffic density and broadcast signaling delay.
