Probabilistic models for quality control in environmental sensor networks

Creator:

Dereszynski, Ethan W.

Abstract:

Networks of distributed, remote sensors are providing ecological scientists with a view of our environment that is unprecedented in detail. However, these networks are subject to harsh conditions, which lead to malfunctions in individual sensors and failures in network communications. This behavior manifests as corrupt or missing measurements in the...

: Probabilistic Models for Quality Control in Environmental Sensor Networks Abstract approved: Thomas G
A probabilistic model for anomaly detection in remote sensor streams

Creator:

Dereszynski, Ethan W.

Abstract:

Remote sensors are becoming the standard for observing and recording ecological data in the field. Such sensors can record data at fine temporal resolutions, and they can operate under extreme conditions prohibitive to human access. Unfortunately, sensor data streams exhibit many kinds of errors ranging from corrupt communications to partial...

Quantity is Nothing without Quality: Automated QA/QC for Streaming Environmental Sensor Data

Creator:

Campbell, John L., Rustad, Lindsey E., Porter, John H., Taylor, Jeffrey R., Dereszynski, Ethan W., Shanley, James B., Gries, Corinna, Henshaw, Donald L., Martin, Mary E., Sheldon, wade M., and Boose, Emery R.

Abstract:

Sensor networks are revolutionizing environmental monitoring by producing massive quantities of data that are being made publically available in near real time. These data streams pose a challenge for ecologists because traditional approaches to quality assurance and quality control are no longer practical when confronted with the size of these...
