Identifying defective nodes in wireless sensor networks

摘要: Wireless sensor networks (WSNs) have become ubiquitous, e.g., in logistics, smart manufacturing, city infrastructures or vehicular ad-hoc networks. WSNs tend to rely on that are prone a wide range of different defects, communication failures, faulty sensors nodes been tampered with. Additionally, dealing with defects is challenging, as might occur only occasionally. In this paper, we introduce SEDEL, our approach for Sensor nEtwork DEfect Localization. SEDEL helps the WSN operator pinpoint defective routing topology WSN. particular, let store graph representations topology, together information if has produced errors. Based information, assigns each node suspiciousness score correlated defect probability. Thus, can be used any kind defect, and does not known, long decide certain processing correct not. We evaluated real sensor-node deployment. Our evaluation shows assigned high probability vast majority experiments.
