MASID: Multi-Agent System for Intrusion Detection in MANET

In this paper we focus on intrusion detection in the mobile ad hoc networks (MANETs). Starting by an overview of the existing work in this field, and ending up with the proposal of a new distributed and cooperative architecture for intrusion detection. In order to overcome the weaknesses and flaws of the existing MANET intrusion detection systems (IDSs), this architecture integrates an agent-based detection process. So, the main principle of the proposed architecture is based on: (a) the distribution which is achieved through the implementation of a local intrusion detection system on each network node, and (b) the cooperation that is guaranteed by mobile and stationary agents´ collaboration. In that way we were able to have an IDS with so many interesting features such as: flexibility, distribution and cooperation, autonomy, lightweight, reactivity and fault tolerance which are extremely desired for any MANET intrusion detection system.
