Future wireless communication systems will be greatly dependent on the instantaneous deployment of independent mobile users. Some of the notable and interesting examples include creating sustainable, well organized, well planned, effective, and active communication systems for emergency/exigency/crises operations, catastrophe relief efforts, and military networks. Such networking situations depend on distributed, dispersed and disorganized connectivity, and can be designed as applications of Mobile Ad Hoc networks. A MANET is a self-governing and self-organizing collection of mobile nodes that communicate over relatively bandwidth constrained wireless links. The network is decentralized and disseminated, where all networking including discovering the topology and conveying the messages must be accomplished by the nodes themselves, i.e, routing capabilities are assimilated into mobile nodes. However, determining feasible routing paths and distributing messages in a decentralized environment where topology varies is a difficult job. Factors such as the open medium and vast distribution of nodes, topological changes, variable wireless link quality, and propagation path loss become pertinent issues and make MANET unprotected to intrusions. Thus it becomes pivotal to develop a systematic intrusion detection mechanisms to secure MANET from intruders. In this paper, we put forward and apply an efficient intrusion detection system named Enhanced Adaptive Acknowledgment (EAACK) specially designed for MANETs which performs better than the previous techniques such as Watchdog, TWOACK and AACK.
