Detecting Reporting Anomalies in Streaming Sensing Systems
نویسندگان
چکیده
Sensor networks must be monitored to identify and correct problems as they occur. We present a comparison of two approaches to monitoring deployed sensors. The first relies on configuration parameters to define expected reporting behavior. The second automatically identifies normal reporting patterns based on a combination of configuration parameters and an analysis of reporting times. Using these patterns, the system notifies personnel of possible malfunctions. We present empirical evaluations in the context of the Intelligent River R © system [11].

The Possibility of Selective Adsorption and Sensing of the Noble Gaseous Species by the C20 Fullerene, the Graphene Sheets, and the N4B4 Cluster
There are only a handful reports about the sensor systems having the ability of detecting the existence of the noble gases. Chemical reluctance of these gaseous species causes them to have no chemical interactions like hydrogen bonding with the chemically designed nano-sized sensors. Noble gasses usually have no atomic charges nor do change the total polarity of the molecular sensor systems. Th...
متن کاملReal-Time Anomaly Detection for Streaming Analytics
Much of the worlds data is streaming, time-series data, where anomalies give significant information in critical situations. Yet detecting anomalies in streaming data is a difficult task, requiring detectors to process data in real-time, and learn while simultaneously making predictions. We present a novel anomaly detection technique based on an on-line sequence memory algorithm called Hierarch...
