Vehicular Context Cloud Networking for Intelligent Transport Systems

Since few years, cloud computing has been adopted vehicular networks and many issues have been handled within such networks as cloud architecture and application distribution This paper proposes a new mechanism, denoted Geographical Vehicular Central Data Networking (GeoVCDN), to distribute interests in the context of Vehicular Cloud Networking (VCN). Our mechanism takes the benefit from the ETSI (European Telecommunications Standardisation Institute) standardized sent messages such as Cooperative Awareness Messages (CAM) to distribute the interests and to collect new data. Moreover, our approach allows to use the multi-hop forwarding capability of vehicular networks to spread the new data. Extensive simulations show a real enhancement of our solution compared to existing ones in particular two well known mechanism: Rendez-vous Networks (RENE) and Named Data Networks (NDN).
