In Situ Calibration Algorithms for Environmental Sensor Networks: A Review - IEEE Journals & Magazine
The recent developments in both nanotechnologies and wireless technologies have enabled the rise of small, low-cost and energy-efficient environmental sensing devices. Many projects involving dense sensor networks deployments have followed, in particular, within the Smart City trend. If such deployments are now within economical and technical reach, their maintenance and reliability remain, however, a challenge. In particular, reaching, then maintaining, the targeted quality of measurement throughout deployment duration is an important issue. Indeed, factory calibration is too expensive for systematic application to low-cost sensors, as these sensors are usually prone to drifting because of premature aging.....
