Vehicular Ad-hoc Networks (VANETs) are now considered to be suitable for enhancing road safety and efficiency in vehicular environment. Especially, due to the affluent spectrum resource, supports for non-safety relevant services, like inter-vehicle entertainments, are also under investigation. However, in the vehicular environments, the nodes can experience(More)
We introduce and analyze a new Markov model of the IEEE 802.11 Distributed Coordination Function (DCF) for wireless networks. The new model is derived from a detailed DCF description where transition probabilities are determined by precise estimates of collision probabilities based on network topology and node states. For steady state calculations, we(More)
