Mobile AdHoc networks are self-configuring and self-organizing multi-hop wireless networks. A mobile Adhoc Network (MANET) is a collection of autonomous mobile users communicating over bandwidth constrained wireless links. Due to the mobile nodes, the topology of the network keeps changing unpredictably and rapidly over time. A selective black hole attack on MANET refers to an attack by a malicious node, which forcibly acquires the route from source to a destination by the falsification of sequence number and hop count of the routing message. As selective black hole is a node that can optimally and alternately perform a selective black hole attack or perform as a normal node. In this paper, we propose a method of activating the promiscuous mode and hence further data packet loss is prevented. Finally, we analyze the performance of the nodes after the inclusion of promiscuous mode.
