Energy Consumption Simulation of Different Distributed Intrusion Detection Approaches

The proliferation of wideband and Internet technologies in the last decade, has generated a significant growth of the risk of security threats hidden in single packets. This fact has lead ISP networks to the adoption of Intrusion Detection Systems, burdening the basic routing with packets inspection, in order to provide a secure connection service. Currently, packet analysis is provided by many ISPs but it has a high impact in term of performance and energy consumption; this makes the choice of the optimal IDS strategy both quite complex and a key issue. To this aim, IDS strategies have been deeply investigated in term of performance, however, the assessment of the energy consumption is generally unexplored. In this paper, we simulate different scenarios for distributed intrusion detection and we leverage an energy consumption model to evaluate the energy consumption caused by early or late discovery of rogue packets.
