In a vehicular ad hoc network (VANET), cars can exchange infor- mation by using short-range wireless communications. Along with the opportunities oered by vehicular networks, a number of challenges also arise. In particular, most works so far have focused on a push model, where potentially useful data are pushed towards vehicles. The use of pull models, that would allow users to send queries to a set of cars in order to nd the desired information, has not been studied in depth. The main challenge for pull models is the diculty to route the dif- ferent results towards the query originator in a highly dynamic network where the nodes move very quickly. To solve this issue, we propose Geo- Vanet, an anonymous and non-intrusive geographic routing protocol which ensures that the sender of a query can get a consistent answer. Our goal is to ensure that the user will be able to retrieve the query results within a bounded time. To prove the eectiveness of GeoVanet, an extensive experimental evaluation has been performed, that proves the interest of the proposal for both rural and urban areas. It shows that up to 80% of the available query results are delivered to the user.
