Black hole attack detection and prevention mechanism for mobile ad-hoc networks

In the mobile Ad-hoc networks, there exists various challenges in packet data delivery mechanism. Therefore transferring data from one node to other node is challenging. One of such attack is the black hole (BH) attack in a network. We are proposing a mechanism for the detection and prevention of BH attack in the mobile ad hoc network. The routing protocol that we are using is Ad hoc on-demand distance vector routing (AODV). As we know that AODV is vulnerable to BH attack, where a node pretends as a shortest path node and gives false information to the sender. In this paper we not only preventing but also detecting the BH node. The simulator used here to implement the mechanism is NS 2 and result proved the effectiveness of model as the throughput is very high as compared to AODV that does not have proposed mechanism.
