Autonomous mobile nodes constitute a temporary network without fixed infrastructures, as ad hoc networks. Each mobile node is independent and therefore both act like host and router. Because of this behavior, security is the major difficult task in such networks, in which every node can able to add or left the network without permission. Black Hole Attack is now one of MANET's big security concerns. It happens when the black hole connects to the network. This node runs like it has the path to the target and then takes all of the packets and therefore does not transmit to the intended location, but keeps dropping all the packets during the phase of route discovery. In this research, we simulated the attack by proposed routing method called IDSAODV using NS2, keeping in mind the network & attacker mobility with the attacker location & eventually the number of attackers. Despite the identification of the black hole attack to restart the delivery of data, the test results demonstrated that there is a circumvention of the black hole node but a reopening of the path to the real destination. Finally, we have achieved overall high performance in terms of throughput, packet rate & end-to-ends delay for all scenarios
