Software Calibration of Wirelessly Networked Sensors

This paper presents our work with wireless sensor networks for the calibration of the embedded sensor chips located in each wireless sensor networks node. We propose a software compensation applied on data sources for each devices. We implement such a calibration process at the initialization of the wireless sensor networks and we propose a software module on each node to regularly improve the measurement accuracy. The results shows the temperature measurements improvements for our energy efficiency in building testbed.
