Title
Model-Based Event Detection in Wireless Sensor Networks
Abstract
We present an application of statistical signal processing techniques to the problem of event detection in wireless sensor networks used for environmental monitoring. The proposed approach uses the well-established Principal Component Analysis (PCA) technique to build a compact model of the observed phenomena that cap- tures daily and seasonal trends in the collected measurements. We subsequently use the divergence between actual measurements and model predictions to detect the existence of discrete event s within the collected data streams. Our preliminary results show th at this event detection mechanism is sensitive enough to detect the onset of rain events using the temperature modality of a wireless s ensor network.
