Voting based revocation mechanism in MANET using direct and recommendation trust

Abstract

The growing use of mobile devices in MANET has influenced a lot of application in the field of wireless technology. To provide security to the network is a major challenge. Of all the goals of wireless network security, authentication is crucial. Communication among authenticated nodes is done with digital certificate. Nodes which misbehave in the cluster are eliminated from the network by revoking its certificate. Our proposed system uses voting based mechanism using trust of the node present in the black list. The trust value calculation is done for all the nodes in black list by cluster head using direct and recommendation trust. Total trust is the combination of 80% of direct trust and 20% of indirect trust. Revocation is done based on the threshold to reduce the false accusation. Simulation result of the proposed system using NS-2 shows improved results when compared with existing scheme in terms of malicious node revocation, false revocation, normalized time to revocation, revocation accuracy ratio and number of warned nodes. Simulation results articulate that the proposed mechanism yields an exemplary outcome for providing secure communication in MANETs.
