A System for Power-Aware Agent-Based Intrusion Detection (SPAID) in Wireless Ad Hoc Networks

In this paper, we propose a distributed hierarchical intrusion detection system, for ad hoc wireless networks, based on a power level metric for potential ad hoc hosts, which is used to determine the duration for which a particular node can support a network monitoring node. We propose an iterative power-aware, power-optimal solution to identifying nodes for distributed agent-based intrusion detection. The advantages that our approach entails are several, not least of which is the inherent flexibility SPAID provides. We consider minimally mobile networks in this paper, and considerations apt for mobile ad hoc networks and dynamism issues are earmarked for future research. Comprehensive simulations were carried out to analyze and clearly delineate the variations in performance of our approach with changing density of wireless networks, and the effect of parametric variations such as hop-radius.
