Continuous, Online Monitoring and Analysis in Large Water Distribution Networks

Clean drinking water and safe water supply is vital to our life. Recent advances in technologies have made it possible to deploy smart sensor networks in large water distribution networks to monitor and identify the water quality online. In such a large-scale real-time monitoring application, large amounts of data stream out of multiple concurrent sensors continuously. In this paper, we present a system to monitor and analyze the sensor data streams online, find and summarize the spatio-temporal distribution patterns and correlations in co-evolving data, detect contamination events rapidly and facilitate corrective actions or notification. The system consists of an online data mining engine and a GUI providing the user with the current patterns discovered in the network, and an alerter notifying the user if there is anomalous water quality in the network.http://gateway.webofknowledge.com/gateway/Gateway.cgi?GWVersion=2&SrcApp=PARTNER_APP&SrcAuth=LinksAMR&KeyUT=WOS:000295216600125&DestLinkType=FullRecord&DestApp=ALL_WOS&UsrCustomerID=8e1609b174ce4e31116a60747a720701Computer Science, Artificial IntelligenceComputer Science, Information SystemsEngineering, Electrical & ElectronicEICPCI-S(ISTP)
