Abstract MANET, a wireless, infrastructure-less, ad-hoc network, uses a dynamic topology rendering for the establishment of connections much easier in any given conditions. The black hole attack is a malicious activity that is performed in MANET which causes depletion of the network. It poses a threat to MANET by incorporating malicious nodes into the network which gives fake routing information to the source node. As the black hole attack acquires the data from the source node, it drops the data packet from the network resulting in the depletion of the network. In this paper, to tackle the black hole attack, we have proposed a node credibility-based approach focusing on Andrews plot to project the node credibility after a few transactions which infer that a high node with high node credibility is the more trusted node in the network. We have used Network Simulator software for the creation of MANET scenarios.
