Non DTN Geographic Routing Protocols for Vehicular Ad Hoc Networks
Vehicular Ad Hoc Networks are highly mobile wireless ad hoc networks. Routing of data in VANETs is a challenging task due to rapidly changing topology and high speed mobility of vehicles. Geographic routing protocols are becoming popular due to advancement and availability of GPS devices. In this paper, the authors review the existing non DTN Geographic Routing Protocols for VANETs and also provide a qualitative comparison of them. Vehicular Ad hoc NETworks (VANET), a new technology to build a wireless network between vehicles (V2V) and Vehicles To Infrastructure(V2I).VANETs are based on short-range wireless communication (e.g., IEEE 802.11) between vehicles.
