A Concept of Time Windows Length Selection in Stream Databases in the Context of Sensor Networks Monitoring

Abstract

Monitoring systems are a source of large amounts of data. These streams of data flow down as information which, in the case of sensor networks is often associated with the measurement of the selected physical signals. Processing of these data is a non-trivial issue, because accurate calculations often require dedicated solutions and large computing power. In the case of flood embankment monitoring systems the essence of the calculation is the analysis of time series in terms of similarities to herald danger scenarios. This analysis also includes data series from neighboring sensors, which increases the difficulty of the calculation. This paper proposes the concept of a data analysis system, allowing for dynamic evaluation of the embankments. © Springer International Publishing Switzerland 2015.
