Abstract

In this work, we present a mechanism, denoted ADAGA -- P, for managing sensor-field regression models. ADAGA -- P implements an in-network data prediction mechanism in order to only transmit data which are novelties for a regression model applied by ADAGA -- P. Experiments using real data have been executed to validate our approach. The results show that ADAGA -- P is quite efficient regarding communication cost and the number of executed float-point operations. In fact, the energy consumption rate to run ADAGA -- P is 15 times lower than the energy consumed by kernel distributed regression for an RMSE difference of 0.003.
