The Berkeley "Smart Dust" Concept ü Spread thousands of wireless sensor nodes casually over

The Berkeley "Smart Dust" Concept ü Spread thousands of wireless sensor nodes casually over an arbitrary area of interest ü They self-organize into a network conveying arbitrary information from any point to any other at whatever bandwidth is demanded. . . ü. . while operating at incredibly low energy usage (i. e, off most of the time) to run for years on small batteries and harvested energy ü. . and being extremely responsive in times of key activity ü. . without ever bothering you about design considerations, intended usage, faults, or constraints (Stevie wants to be 6 foot tall) From Culler

Current Fire. Bug Tasks • Race/deadlocks still exist in sensor board driver code. • Weather and air quality concerns limit controlled burn opportunities. We have to be able to move fast when necessary. • “Uplink” details for remote deployment are still sketchy.
