Hybrid Agents for Power-Aware Intrusion Detection in Highly Mobile Ad Hoc Networks

Abstract

Highly mobile ad hoc networks with their changing topology and distributed nature are more prone to intruders. The efficiency of an Intrusion Detection System in the case of an ad hoc network is not only determined by its dynamicity in monitoring but also by its flexibility in utilizing the available power in each of its nodes. In this paper, we propose a hybrid intrusion detection system, 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. Power - aware Hybrid Intrusion Detection System (PHIDS) focuses on the available power level in each of the nodes and determines the network monitors. Power aware intrusion detection using hybrid agents result in maintaining power and provides an iterative poweroptimal solution to identify fewer nodes for distributed agent-based intrusion detection.
