Now a day’s VANET (Vehicular ad-hoc network) is a unique environment such as vastly active topology, repeatedly incoherent network, safety-related application of transmission of delay is very hard. VANETS are mostly used in traffic scenario of urban and highway, these acts like a sensor. The method is proposed on VANET and optimal distance is improved based on routing protocol in built-up traffic area, we apply Ad-Hoc on multiple distance demand vector (AOMDV) routing protocol ,this approach gives the optimal performance compared with AD-Hoc on demand vector routing protocol(AODV).These result shows the improved performance as compared with AODV by using Network Simulator (NS2).
