Submitted Abstract

Vehicular Ad hoc Networks (VANETs) [I] have been receiving a lot of interest from academia, automotive industry, and government, as they hold the potential to enable a wide range of applications and services, improving safety and comfort on the road [Willke2009].So far the main motivation for vehicular communications has been in the support for safety applications, which have been estimated to help avoiding up to 79 percent of all traffic accidents [NHTSA]. More recently, autonomous and coordinated driving applications are also emerging as another strong incentive for the adoption of VANETs [Google] [EN-V]. At the same time, infotainment services continue to be of interest for drivers which are willing to exchange video streams, and other type of contents, while being in the car. These different applications, based on the exchange of data through vehicle-to-vehicle (V2V) and/or vehicle to infrastructure (V2I) communications, are destined to converge all on the same network. Due to the volatility of the vehicular environment, VANETs are characterized by (i) a dynamic topology, (ii) short-lived intermittent wireless connectivity, and (iii) a cooperative and decentralized communication paradigm. All these features make information exchange in VANETs a challenging task. The CONTACT project aims to provide Quality of Service (QoS) support in VANETs by developing a set of communication techniques which efficiently adapt, at the same time, to the highly volatile and unstable vehicular environment, to content attributes and properties, and to application performance requirements. In detail, CONTACT will adopt strategies based on the type of content exchanged (alerts, driving coordination, informational) as well as on its context attributes (such as location of origin, geographical range of interest, time of validity). To this aim, CONTACT will investigate and try to exploit the use of three different emerging approaches: Content-Centric Networking (CCN), Software Defined Networking (SDN), and Floating Content. Even though not designed for VANETs, they can bring big advantages to vehicular applications, by improving content availability, replication and distribution.
