Detecting anomalies in a sensor-networked environment

摘要

In a method for detecting anomalies in a sensor-networked environment, packages of data are received from a plurality of sensors located in the environment. At least one candidate problem location in the environment is identified based upon data contained in the packages. A principal components analysis is performed on the data collected from sensors associated with the identified at least one candidate problem location to identify a number of hidden variables and the number of hidden variables are analyzed to detect anomalies in the environment. In addition, detected anomalies are outputted. An analyzer for performing the method is provided.
