2009 Ninth Annual International Symposium on Applications and the Internet
Measurement Analysis of the Live E! Sensor Network: Spatial-Temporal Correlations and Data Aggregation
Bellevue, Washington, USA
July 20-July 24
ISBN: 978-0-7695-3700-9
The (Japanese) Live E! project consists of a large sensor network of spatially distributed weather stations measuring different environmental quantities such as temperature, humidity, pressure, etc. Our goal is to conduct the first analysis on this huge data set of the structures of correlations both in time and space observed on data, for given quantity among stations, and for a given station, among sensors. Finally, we investigate a data aggregation algorithm, based on polynomial regression, and we show how it can reduce significatively the overall data traffic.
Index Terms:
Wireless sensor networks, time series analysis, time series decomposition, temporal and spatial correlation, data aggregation
