A black hole attack in ad hoc network refers to an attack by malicious nodes, which forcibly acquires the route from a source to destination by falsely advertising shortest hop count to reach the destination node. In this paper, the authors present a Modified Dynamic Source Routing protocol (MDSR) to detect and prevent selective black hole attack. Selective black hole attack is a special kind of black hole attack where malicious nodes drop the data packets selectively. They proposed an Intrusion Detection System (IDS) where the IDS nodes are set in promiscuous mode only when required, to detect the abnormal difference in the of data packets being forwarded by a node.
