Non-DTN Geographic Unicast Routing Protocol for VANET: State of the Art

Abstract

The numbers of vehicles are increased on the roads exponentially in recent years, so the challenges on the roads are also increased like roads are full, safety problem, speed etc. One solution for these problem is to form a Vehicular Ad-Hoc Networks (VANET). VANETs are a special kind of Mobile Ad Hoc Network, (MANET), in which vehicles are the nodes and each vehicle have the transmission capabilities. There are different routing protocols are proposed. This paper describe different non-DTN geographical unicast routing protocols, categorize in to beacon, non-beacon and hybrid and compare with different parameter
