In recent years, new architectures and technologies have been proposed for Vehicular ad hoc networks (VANETs).However, the experiments to validate these proposals tend to overlook the most important and representative factors. Moreover, the scenarios simulated tend to be very simplistic (highways or Manhattan-based layouts), which could seriously affect the validity of the obtained results. In this...
As deploying Vehicular Ad Hoc NETworks (VANETs) costs large amounts of resources, it is crucial that governments and companies make a thorough estimation and comparison of the benefits and the costs. The network connectivity is an important factor we should take care of, because it can greatly affect the performance of VANETs and further affect how much we can benefit from VANETs. We use percolation...
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...
