Intrusion Detection Systems (IDS) are systems comprised of software and hardware and their role is to automatically detect network intrusions. Ad hoc networks are autonomous self-organized wireless networks without steady infrastructure where devices are using their wireless interfaces to communicate. Due to the absence of steady infrastructure these networks are vulnerable to a number of attacks. The current IDS architectures proposed for Ad Hoc networks are based on cooperative methodologies: hierarchical and cooperative architectures. In this dissertation an extensive study on suggested cooperative IDS architectures will be presented and their advantages and disadvantages will be thoroughly analyzed.
