Efficient data dissemination for secured communication in VANET

Vehicular ad hoc networks (VANETs) is an emerging technology that provide efficient and reliable data communication between vehicles using Roadside units (RSU). But it requires efficient and robust routing protocols for their communication. We exploit the fixed infrastructure of Roadside units (RSUs) to efficiently and reliably route packets in VANETs. All the RSUs are interconnected with each other. Our VANET system operates by using vehicles to carry and forward messages from a source vehicle to a nearby RSU and, if needed, route these messages through the RSU network and, finally send them from an RSU to the destination vehicle. All the RSUs are interconnected with each other. To implement the same vehicle communication with server based manner. By our server based method the vanet communication will be more effective. The sever will response for table maintenance that data in its data-base. In our project concept we have the chance to reduced delay with maximized throughput in VANET and also we can able to predict the traffic density of particular area of our network. We evaluate the performance of our system using the ns2 simulation and compare our result with existing system.
