This paper studies the multihop packet delivery delay in a low density vehicular ad hoc network (VANET). We address a disrupted vehicle-to-infrastructure communication scenario, where an end-to-end path is unlikely to exist between a vehicle and the nearest road side unit (RSU). We present an analytical framework, which takes into account the randomness of vehicle data traffic and the statistical...
End-to-end delay is critical for the real-time safety message delivery in Vehicular Ad Hoc Networks (VANETs). In this paper, we present an analytical model to evaluate the impact of transmission range on the end-to-end delay in 802.11p-based VANETs. Compared with the previous works, our model derives a concise expression of the transmission delay in saturated networks, and obtains the service rate...
In this paper, we present analytical models to study the packets delivery probability on intersections for VANETs(Vehicular ad hoc networks) in city scenarios. These models can help better understand data propagation in this environment. We show that the delivery probability is strongly related to the traffic conditions of the road where the information is to be transmitted. We also validate our analytical...
In view of some shortcomings of existing broadcast algorithms for Vehicular Ad Hoc Networks (VANET), including ignoring the differences of transmission range among different vehicles, and disseminating emergency messages based only on vehicles in the one-way lane etc., a novel broadcast algorithm for VANET called Transmission Range Adaptive Broadcast (TRAB) is proposed in this paper. Considering the...
