Abstract
The development of Vehicular Adhoc Networks VANET has witnessed the release of various multimedia services and made it important to develop architectures and routing protocols capable of a handling the multimedia QoSs requirements and the realtime services’ constraints b maximizing the network coverage and c managing resources on the Road Side Units RSUs in order to guarantee the continuous delivery of realtime servicesIn this work we provide a novel 4Gbased VANET heterogeneous architecture which integrates IEEE 80211p and 3GPP LTE access networks to provide access to multimedia services A treebased network access scheme is developed providing a rapid connection and handover to highly mobility vehicles and allowing to maximize at a large extent the network coverage beyond the area uncovered by RSUs in the form of LTE eNodeBs Techniques for the proactive resources provision on the RSUs and the management of QoSaware vertical and horizontal handovers are developed
