Dissemination of information in inter-vehicle ad hoc networks

This paper focuses on intelligent transportation systems and more precisely on inter-vehicle ad hoc networks. Such networks are highly dynamic due to the movements of the vehicles and the short range of the wireless communications. Thus, for example, we can only rely on short interactions between the vehicles to exchange data about relevant events. We propose a new dissemination technique for vehicles to share information using V2V communications. Our goal is to make possible the exchange of information between vehicles when they encounter each other, taking into account the relevance of the data to the drivers. The originality of our proposal is that it relies on an encounter probability to disseminate data about any type of event (e.g., available parking spaces, obstacles in the road, information relative to the coordination of vehicles in emergency situations, etc.) in the network.
