Abstract: This paper proposes a novel trust based routing mechanism to mitigate black hole attack in Mobile ad hoc Networks (MANETs). The proposed model is based on Trust Correlation Service (TCS) mechanism. This aggregates and distributes the trust among nodes that are participating in the wireless network. The trust for a node and the correlation score for various pairs of nodes is computed before establishing the route for communication between the source and destination. The Trust for a node is computed based on various factors such as node reputation, its ability to defend against various attacks and unauthorized resource utilization. A correlation score for a pair of nodes is computed based on their internal trust, required level of trust, number of packet sent and delivered to the destination. It is computed for every pair of intermediate nodes along the path from source to destination. In this paper, the Dynamic Source Routing (DSR) Protocol is modified to find a trusted route rather than the shortest route between source and destination. The proposed trust based model yields reduced data drop rate and end-to-end delay. The simulation results achieved are promising with improved throughput.
