Network Calibrarion of Embedded Sensors

The focus of this project is to provide methods for calibra-tion of sensor nodes in sensor networks. The importance of the calibration problem is to compensate for the sensor read-ing drifts that occur due to systematic errors, noise or sen-sor degradation. The objective is to provide calibration tech-niques that apply on collaborative sensors autonomously, i.e. without supervision. Our work involves: a) distributed proce-dures to identify erroneous sensors; and b) a simulator frame-work for a sensor net drift calibration setups. 1. Overview • Motivation. The deployment of sensor networks has been growing in scale and scope with new applications in embed-ded and challenging environments. This progress has been facilitated by advances in nanoscale electronics that can be in
