Secure Cluster based Self Organized Authentication with Key Management Scheme in Vehicular Adhoc Network

Vehicular Ad hoc Networks (VANETs) are the promising approach and also a key component of intelligent transport system. Its main aim is to provide driver convenience and safety. To improve security and balance the message overload the cluster approach and the key distribution technique is used. In this model first the network is analyzed based on its parameters and develop three models based on road condition and clusters are formed with every node in the network. The group key management scheme improves scalability, reliability, and security of the VANET. Group key management in VANET solves the issues associated with membership changes. In this phase a model for sending a file from the source to the destination using the mesh network is implemented and the core resolution algorithm for finding the core node in that and the expanded ring search algorithm for identifying the next mesh address in the path to reach the destination. Through this the scalability and the efficiency of network is improved.
