Vehicular ad hoc networks (VANETs) enable vehicles to communicate with each other but require efficient and robust routing protocols for their success. In this paper, we exploit the infrastructure of roadside units (RSUs) to efficiently and reliably route packets in VANETs. Our system operates by using vehicles to carry and forward messages from a source vehicle to a nearby RSU and, “also adding a digital signature by advanced encryption standards to every node for the security purpose”. RSU‟s are formed as cluster for consuming less energy and life time also increases. We evaluate the performance of our system using the ns2 simulation platform and compare our scheme to existing solutions. Then traffic is generated by VANETMOBISIM software. The results prove the feasibility and efficiency of our scheme.
