In an ad hoc network, a black hole attack occurs when hostile nodes forcefully acquire the route from a source to a destination by fraudulently advertising the shortest hop count to reach the target node. A Modified Dynamic Source Routing Protocol (MDSR) is presented in this article to identify and avoid selective black hole attacks. A selective black hole attack is a kind of black hole attack in which hostile nodes selectively discard data packets. To identify the anomalous difference in the amount of data packets sent by a node, we suggested an Intrusion Detection System (IDS) in which the IDS nodes are configured in promiscuous mode only when needed. When an anomaly is discovered, the adjacent IDS node sends out a block message to other nodes in the network, instructing them to work together to remove the malicious node from the network. Glomosim is used in the suggested method to verify the efficacy of the proposed intrusion detection system.
