Abstract
VANET (Vehicular Ad Hoc Network) is a special case about MANET(Mobile Ad Hoc Network), has also received extensive attention as a part of ITS (Intelligent Transportation System). Although it is a promising technology, due to different kinds of factors (such as high speed, particularity of road, traffic system, etc), the routing technology becomes the important challenging problem in Vehicle Ad Hoc Network. We assume each vehicle is equipped with a short range wireless communication device, as is a controller node placed in every intersection with data forwarding system. This paper sets up a mobility model at intersection and present mathematical analysis by the use of Markov analysis method, then proposes a novel routing strategy and shows the performance of the proposed scheme is better than the traditional flood one by simulation.
