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, it makes use of the infrastructure of roadside units (RSUs) to efficiently and reliably route packets in VANETs. In the vehicular adhoc networks operates vehicles to carry and forward messages from a source vehicle to a nearby RSU and, if needed, route this information through the RSU network and, finally send them from an RSU to the particular vehicle. Our system is mostly critical for users who are far apart and want to communicate using their vehicles’ onboard units. Many current paradigms, like online networks, will greatly benefit from a system like ours to enable users on the road to exchange different types of data. It evaluates the performance of our system using the simulation process and compares our scheme to old solutions. The results improve the efficiency.
