This Paper discusses about the capability of the current routing protocol of MANET for VANET. VANET is derived from MANET and it is a network consisting of vehicles, which can communicate between them wirelessly. In high traffic conditions the message should deliver correctly between the vehicles and the communication is established with the help of Road side Units. A dynamic topology with mobility patterns and different channel time behavior characterize VANETs. The network traffic requirements differ for VANET. In this paper, w Zone routing Protocol (ZRP) is utilized to improve the parameters of VANET like less communication delay and delivering the messages on time compared to AODV and DSR protocols while the vehicles are moving at high speeds. The results are obtained by simulation using a simulation scenario.
