Executive Summary

In this paper, the authors propose a novel dynamic approach for detecting Denial of Service (DoS) attacks in cluster-based sensor networks. Their method is based on the election of controller nodes called cNodes which observe and report DoS attack activities. Each cluster contains cNodes and normal sensor nodes. The role of a cNode is to analyze traffic and to send back a warning to the cluster head if any abnormal traffic is detected. The election of these cNodes is dynamic, and done periodically and based on a Multiplicative Linear-Congruential Generator (MLCG).
