Abstract

The focus of this work is to propose a integrated trust based detection and authentication based on ANT based authenticated Routing in MANET. Our trust management system combines the grey theory and fuzzy sets for calculating the trust value. This trust management framework designed to be robust against many attacks. Based on fuzzy based grey theory trust value is calculated. After trust value is calculated Ant based Authenticated routing is used to transmit a packet from source node to the destination node. Ant colony based routing algorithm (ARA) is used for routing the data packets. This routing algorithm is consists of three phases. Route Discovery, Route Maintenance and Route failure handling. During route discovery phase new routes will be created. FANT will establish the pheromone track to the source node wherelse BANT will establish the pheromone track to the destination node. When source node sends the data it includes FA with a trust value included to it. The movement of FA will be decided based on the decision rule. FA moves by using the rule and will verify the trust value of the visited node is greater than trust threshold value. When FA reaches the destination BA will be generated and the information collected by FA will be given to BA. The BA takes the same path which FA used to reach the destination. Based on simulation results we show the proposed. Trust based Intrusion detection system using fuzzy technique and ANT based Authentication in MANET enhances the secure data communication.
