Routing and Data Diffusion in Vehicular Ad Hoc Networks

Abstract: Data delivery is a crucial task in vehicular networks since current applications require the cooperation of each and every vehicle. Regarding the interaction between the driver and the vehicle, as defined by the National Highway Traffic Safety Administration, a fully autonomous car performs a given driving task under any variety of conditions. Therefore, all decisions taken by the system become crucial, simply because no actual human hand is on the “steering wheel” of the driving system. Information provided by sensors make it possible to construct a local vision of the vehicle; however, the construction of a global vision of the actual situation at hand requires the exchange of information and data. This task is ensured by data delivery services, with the aim of being efficient and reliable. Security aspects must also be taken into account in order to disseminate, receive and process reliable information and data.
