Distributed PCA-based anomaly detection in wireless sensor networks

Abstract

Detecting anomalies is an important challenge for intrusion detection and fault diagnosis in wireless sensor networks (WSNs). In this paper, we propose a distributed energy-efficient approach for detecting anomalies in sensed data in a WSN. The anomalies in sensed data can be caused due to compromised or malfunctioning nodes. In the proposed approach, we… (More)
