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, we review the existing non DTN Geographic Routing Protocols for VANETs and also provide a qualitative comparison of them.
