Wireless Sensor Networks Book 2 at the node [1], [13] data reduction becomes an attractive option to conserve the limited energy resources of WSN.Data reduction in WSN is a challenging process as data exists in the form of continuous stream (infinitely large data set) where the adaptation and prediction has to be performed online i.e. at a given instance of time not all the information is available for processing.Typically, the spatial and temporal relations among the data sources in WSN are exploited to achieve fair data reduction rates.Spatial and temporal characteristics of WSN's facilitate in adapting the environment and then predicting it thereby resulting in data reduction.
