Behavioral Intrusion Detection in Mobile Ad Hoc Networks

Abstract

Mobile ad hoc networks due to their ease and speed in setting up are currently used in emergency, military and other areas. Due to their frequent use in applications where the integrity of data and communication is necessary it is very important to provide security for the MANETS. The wireless ad hoc networks have different characteristics when compared to wired networks, so the intrusion detection techniques employed for wired networks can no longer be effective for an ad hoc network when applied directly. Hence the existing Intrusion detection system have to be modified to work effectively in the new network environment .In this paper we give an introduction to MANETS and different intrusion detection techniques. We then propose IDS that uses a quantitative method of anomaly definition based on transmission characteristics and transmission behavior of the nodes
