Detecting Denial-of-Service (DoS) attacks and reducing the energy consumption are two important and frequent requirements in Wireless Sensor Networks (WSNs). In this paper, the authors propose an energy-preserving solution to detect compromised nodes in hierarchically clustered WSNs. DoS detection is based on using dedicated inspector nodes (cNodes) whose role is to analyze the traffic inside a cluster and to send warnings to the cluster head whenever an abnormal behavior (i.e., high packets throughput) is detected. With previously introduced DoS detection schema, cNodes are statically displaced in strategic positions within the network topology.
