Performance Improvement of Delay based road oriented routing protocol for VANET

Vehicular Ad-Hoc Network (VANET) is an prominent new technology develop in ad hoc network, wireless local area network i.e WLAN and cellular technology to achieve intelligent intervehicle communications ,improve road traffic safety and improve the efficiency .Within a given geographical region broadcast based geocast enable to provide efficient data dissemination to vehicle. Broadcast based geocast requires unnecessary retransmissions. The retransmissions is suppressed by controlled by packet forwarding to avoid rebroadcast . Much of existing broadcast suppression method don’t work in urban environment due to building block of communication between two vehicles. In this paper, we propose a an adaptive delay based road oriented routing protocol which adapts delay based data transmission in VANET. This protocol minimize rebroadcasting problem and increase propagation gain. Furthermore, we use two types of forwarding mode to fulfill the requirement of geocast region. Keyword VANET,GR,GF,IF
