Black Hole Attack Detection in MANET Using Mobile Trust Points with Clustering

MANET is a set of mobile nodes in which communication occurs between them using wireless links. Infrastructure less, dynamical topology and Lack of central communication of nodes makes it vulnerable to various kinds of attacks. One of the major security problems is Black Hole attack in which node silently drops the packets in the network. In this paper, we propose a solution to mitigate this attack in MANET using mobile trust points with clustering. The proposed method uses some mobile trust points which monitor the activities of cluster heads to detect the attack and then generate alert in the network if any black hole node detected.
