Vehicular Ad hoc NETworks (VANETs) are a variety of Mobile Ad hoc NETwork (MANET) that are used for communication among vehicles and between vehicles and road side equipments. For efficient communication, the routing protocols must be reliable and robust. In our work we deploy the RoadSide Units (RSUs) as an infrastructure and make use of it for the packet delivery. We carry and forward the message via RSU. In existing work they made use of RSU but that led to overhead and it is a time consuming, since they communicate as: source vehicle to its RSU, between RSUs and then from destination RSU to destination vehicle. But our work helps the user to query the destination RSU and receive the reply by requesting source RSU. And this source RSU communicates intermediate RSUs to communicate to the destination RSU and replies. Here the RSUs are connected. So, this helps in reducing the overhead and time taken. In addition our system provides the security to the user and the information transferred by producing Cryptographic MIXed key (CMIX).
