Moments Based Blind Calibration in Mobile Sensor Networks

In-field calibration of sensor devices is known to be a challenging problem because there is often no access to a controlled signal field and/or a pre-calibrated device to measure the existing signal field. In this paper, we describe a blind calibration scheme that is tailored for sensor networks with mobile nodes. The scheme proposed in this paper exploits the fact that sensor devices are moving in the same region and hence the signal statistics they observe over time are almost the same. Analysis and simulation results are included to demonstrate the effectiveness of the proposed scheme.
