RESUMO

Over the past few years, many research works in Wireless Sensor Networks (WSN) have been focused on node power saving. In order to achieve this goal, the amount of data sent over the node network should be reduced. In this work, we propose an efficient strategy that aggregates and predicts data in WSN, aiming at to reduce the data volume sent over the network and thus maximizing the network lifetime. The proposed prediction strategy, denote ADAGA-p, is based on linear regression model, using data acquired from one or several sensors. Furthermore, ADAGA-p is fully distributed, being executed in-network by several sensors distributed in a WSN. Experimental results show that ADAGA-p is able to reduce power consumption in WSN.
