ABSTRACT Intrusion Detection Systems (IDSs) for Mobile Ad hoc NETworks (MANETs) are indispensable since traditional intrusion prevention based techniques are not strong enough to protect MANETs. However, the dynamic environment of MANETs makes the design and implementation of IDSs a very challenging task. In this paper, we present a non-overlapping Zone-Based Intrusion Detection System (ZBIDS) that fits the requirement of MANETs. On the local detection part, we present a general intrusion detection agent model and propose a Markov Chain based anomaly detection algorithm. We focus on the protection of MANET routing protocols and present the details regarding feature selection, data collection, data preprocess, Markov Chain construction, classifier construction and parameter tuning. We demonstrate that local detection alone cannot achieve desirable performance. Therefore, we further propose a collaboration mechanism among ZBIDS agents and an aggregation algorithm used by gateway nodes. W...
