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. |
