Vehicular Ad hoc NETwork (VANET), which is based on Dedicated Short Range Communication (DSRC), provides an opportunity to enable communication-based cooperative safety systems in order to diminish road ills and improve traffic efficiency. VANET provides a wide range of profitable and documentary applications. VANET exposes unique characteristics that create new challenges. This paper talks about the DSRC technology and its defects in order to achieve reliable content distribution. To optimize the performance of the vehicular networks, a novel network architecture using the cross-layer paradigm is presented.
