collection environment

The experiment was set up on a Mica2 platform, which consisted of 14 sensor nodes randomly deployed inside and outside a lab room. During the measuring period, students walked into and out of lab at random times, which caused anomaly patterns in the RSSI measurements. Finally, a web camera was employed to record activity for ground truth.

network configuration

Wireless sensors communicate with each other by broadcasting and the received signal strength (RSS), defined as the voltage measured by a receiver’s received signal strength indicator circuit (RSSI), was recorded for each pair of transmitting and receiving nodes.

data collection methodology

The experiment was conducted by Prof. Neal Patwari of the University of Utah in the Winter of 2006, when he was a post-doctoral student at the University of Michigan under the guidance of Prof. Alfred O. Hero III. The site of the experiment was the 4th floor of the EECS building, University of Michigan, Ann Arbor.

There were 14 × 13 = 182 pairs of RSSI measurements over a 30 minute period, and each sample was acquired every 0.5 sec.
