In Recent year MANET became a favored technology due to their advantages and applications. MANETs is a collection of data terminals equipped with wireless transceivers that can communicate with one another without using any fixed network infrastructure. MANETs is infrastructure less. Single node act as both transmitter and receiver. Both nodes communicate when they are in the same range. Otherwise, they depend on their neighbors to relay messages. Now a days Intrusion detection system plays vital role in the Security of MANETs. IDSs are able to solve various security attacks in MANETs. However, the distributed nature of nodes can cause various malicious attacks on MANETs. In MANETs the dynamic nature of network topology results in frequent path breaks. To addresses potential security issues. In this paper, we propose a new intrusion detection system called Intelligent Enhanced Adaptive ACKnowledgment (IEAACK) specially design for MANETs. The proposed system introduces a global digital signature to prevent the attacker from forging acknowledgment packets. Furthermore, we propose a trust prediction model to secure the network effectively.
