In future, vehicular networks will play a crucial role in the development of intelligent road traffic systems. Vehicular network will enable cars to exchange crucial road traffic information among them as well as with the traffic signaling infrastructure. In an ad hoc vehicular network generally broadcasting technique is used to disseminate road traffic information. In an IEEE802.11p based vehicular network broadcasting technique could increase the contention level thus increasing information dissemination delay. In this paper we propose a geocasting packet transmission technique to transmit safety messages in a vehicular network which can significantly improve the QoS of a vehicular network. In this work OPNET based simulation models are used to analyze the performance of the proposed protocol. The proposed protocol performance is benchmarked against the standard packet broadcasting protocols proposed for vehicular networks.
