Wireless mobile ad hoc networks @opularly known as MANETs) have been the focus of research in recent times. Rapid and infrastructure-less deployment in emergency and military situations make these nehvorks unique. However, certain inherently vulnerable characteristics lead to security concerns which can prove especially damaging in sensitive situations like militav operations. Intrusion prevention measures are not guaranteed to work all the time since unrelenting attackers can eventually break them down. An Intrusion Detection Scheme (ID$) monitors a netnork and looks for intrusions, thus forming a second wall of defense. In this paper, we have proposed a misuse detection -based IDS for W N E T s . Our protocolindependent design makes use o f a self-adjusting threshold scheme and detects a priori known attack patterns with over 90% accuracy and is generally insensitive to false alarms. Experimental validation has provided signipcant results about non-degradability of network performance with our IDS incorporated for security enhancements.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
