Large-Scale Demonstration of Self-Organizing Wireless Sensor Networks

On Aug. 27, 2001 researchers from the University of California,  Berkeley and the Intel Berkeley Research Lab demonstrated a self-organzing wireless sensor network consisting of over 800 tiny low-power sensor nodes.
Sensor nodes was based on TinyOS.A network discovery operation would show yellow briefly as the discovery wavefront propagated across the network and then turn off the red LED.  Because the discovery takes only a fraction of a second, we would then issue a sequence of commands to illuminate level 1, then level 2, etc. at five second intervals. Test runs in a near empty auditorium discovered a network of 800 nodes that was four levels deep.
