The migration to wireless network from wired network has been a global trend in the past few decades. The open medium and wide distribution of nodes make MANET vulnerable to malicious attackers. A new technique ERACK (Enhanced Robustive ACKnowledgement) method designed for MANET was proposed for the intrusion detection system for MANET by providing secure acknowledgement packets. Enhanced robustive acknowledgement demonstrates higher malicious-behavior-detection rates in certain circumstances while does not greatly affect the network performances.
