Abstract

This work uses an estimator for the predi tion of two parameters: the value of measurement and the value of nodes ina tivity period, to in rease the Wireless Sensor Network autonomy in monitoring a given region. The estimator uses information known by itself and by the sink node to redu e the re onstru tion error of the monitored pro ess below the innovation threshold, parameter used by nodes in de ision of whi h measures must be transmitted. A rst order interpolator is also used to redu e error. Results show a gain in the network lifetime greater than 600% in relation to a network without any energy management. Furthermore, it an be observed that the obtained errors are smaller than the threshold, by using estimator and interpolation.
