A Comprehensive Survey on Secure Intrusion Detection Systems for MANETs

In recent years, MANET become the foremost encouraging area for innovative work of the wireless communication system. It has inherited many vulnerabilities of wireless network because of open medium and self-organizing capability of nodes in MANETs. The intrusion detection system continuously observing for doubtful actions inside a system and then take proper action against them. There are many techniques for intrusion detection in wired system, however applying them directly into wireless environment is not possible. In this paper, we will see various well known intrusion detection system for MANETs with their problems and solutions. In this survey, latest intrusion recognition system specially designed for MANETs known as Enhanced Adaptive Acknowledgement system (EAACK) is discussed. This new scheme solves all the problems of existing intrusion detection systems such as detecting the malicious activities and the presence of false misbehaviour report
