Line in the Sand, September 2003

Line in the Sand was a field experiment at MacDill Air Force base, as part of the technology evaluation and transition efforts in the DARPA NEST program. Our experiment demonstrated the potential of sensor networks for unattended ground sensing over a large, distributed region. More specifically, we showcased how to detect, classify, and track various types of objects (such as persons and cars) using many, resource-poor smart dust sensor nodes.
I was responsible for developing the classification and tracking subsystem for this project. The subsystem includes outlier detection and health monitoring.
