Abstract : Vehicular Ad hoc NETworks are currently attracting the attention of researchers and automobile manufacturers. Disseminating and routing messages in such environments present big challenges due to the very high mobility and the frequent changes of network topology. In this paper, a novel geocast routing protocol is proposed, named DG-CastoR protocol and especially tailored for Infotainment applications in VANETs. It aims to build a virtual community based on future locations prediction of the mobile nodes in the network. We call this community a Rendez-vous group where the nodes may meet in the near future. However, the query is only disseminated between the nodes belonging to the same Rendez-Vous group. Simulation results show that, compared to multicast protocols, DG-CastoR is a robust in managing a large number of nodes in VANETs. It also reduces the traffic load by avoiding the unnecessary packet flooding all over the network.
