The Vehicular Ad hoc NETwork (VANET) is an emerging new technology. Developing multi-hop routing protocols for urban VANETs is a challenging task. VANETs are a kind of Wireless ad hoc network that usually has a routable networking environment on top of a link layer ad hoc network. In this paper, the authors first analyze the unique features of urban VANET and then they move on to discuss the various VANET routing protocols which already have been proposed. They also analyze and compare the various protocols based on some common parameters.
