| Popis: | International audience; Vehicular Ad hoc NETworks are currently attracting the attention of researchers and automobile manufacturers. There are some interesting applications for VANETs such as intelligent transportation systems for safety and comfort driving and Infotainment applications for data exchange between mobile vehicles. 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 is based on the future locations prediction of the neighbors to deliver the query packet in geocast manner to corresponding nodes. Simulation results show that, compared to multicast protocols, DG-CastoR is a robust protocol for handling a large number of nodes in VANETs. It also reduces the traffic load and the energy consumption of the devices by avoiding the unnecessary packet flooding over the network. |
