Executive Summary

In the present paper, the authors have proposed a secured geocaste routing in VANET with two stage efficient communication protocol. The communication protocol operates on two stages. In the first stage vehicles transmit messages within its transmission range of its radar and to the VANET Server. In the second stage VANET Server receives messages from vehicles and sends those messages to all other vehicles belonging to the same geographical region as of sender. Geographical regions are predetermined by VANET Server. One of the interesting features of this protocol is that they use the MANET infrastructure instead of roadside equipments to communicate with VANET server. Added feature of the protocol is that unlike other geocast routing protocol it incorporates security issues too.
