State-of-the-art anomaly detection systems deployed in oilfields are expensive, not scalable to a large number of sensors, require manual operation, and provide data with a long delay. To overcome these problems, we design a wireless sensor network system that detects, identifies, and localizes major anomalies such as blockage and leakage that arise in steamflood and waterflood pipelines in oilfields...
We present the design and placement of system for light monitoring in museums based on wireless sensor networks (WSN). A two-tiered sensor network architecture is formed according to the real light environmental requirements. The proposed system satisfy the requirement from nodes with different function by providing respective hardware structures including sensor nodes (SNs), aggregation nodes (ANs)...
The sewage treatment system plays an important role in the environmental protection of the city, there are several kinds of parameters that need to be monitored simultaneously in order to make the progress under control. Wired monitoring system is still the main approach to monitor the parameter in the existing sewage monitoring system while it has the drawback of highly cost, poor expansion and difficult...
In the application system, obtaining the information of the system at runtime and analyzing them are important for system adjustment. Many runtime metrics can be collected from software systems, and some statistical relationships exist among these metrics. Extracting the information of these metrics from the monitoring data and then analyzing the relationships between these metrics is an effective...
