Data sharing in vehicular ad hoc network (VANET) using DES

Vehicles download the data when passing through a drive through the road (RSU) and then share the data after travelling outside the coverage of RSU.A key issue of downloading cooperative data is how effectively data is shared among them self. Developing an application layer data exchange protocol for the coordination of vehicles to exchange data according to their geographic locations. Coordinated sharing can avoid medium access control (MAC) layer collisions and the hidden terminal effect can be avoided in the multi-hop transmission. A salient feature of the application layer data exchange protocol, in the voluntary services, Vehicles purchase the requested data from service provider via RSUs. The project, intends to propose a cooperative data sharing with secure framework for voluntary services in special vehicles networks (VANETs). We also concentrate on security in the process of downloading data and sharing. Applicants to ensure exclusive access to data applied and security of the vehicles involved in the implementation.
