Dynamic Clustering and Gateway Management in Vehicular Ad-Hoc Networks

Vehicle Ad Hoc NETworks (VANETs), based on IEEE 802.11p, and 3G & beyond networks are characterized by their high data transmission rates and wide range communication respectively. Coupling the high data rates of IEEE 802.11p-based VANETs and the wide coverage area of 3GPP networks (e.g., UMTS), this envisions a VANET-UMTS integrated network architecture. Vehicles are dynamically clustered according to different related metrics. From these clusters, a minimum number of vehicles, equipped with IEEE 802.11p and UTRAN interfaces, are selected as vehicular gateways to link VANET to UMTS. The former aims for enhancing the link stability within the VANET, whereas the latter sustains inter-connectivity of the VANET with the backhaul 3G & beyond network.
