Vehicular Ad Hoc NETwork (VANETs) could achieve flexible communication among vehicles and with infrastructure. VANET provides multi-hop transmission to cover all intended receivers. This multi-hop capability has the potential to increase safety, efficiency and convenience of transportation system. Multi-hop transmission enhances a range of applications including traffic safety and comfort of every day road travel. In most of the envisioned applications, information to all or specific group vehicles inside a certain region is needed to be delivered. These applications rely on unicast, broadcast and geocast approaches. This study presents a review of recent routing protocols for both text and video data transmission.
