2. Who are we? • introductions... nest Retreat

3. Where are we in the project? • 2 of 4 years • got a 1 year head start (Smart Dust, Endeavour) • Open Experimental Platform • provide platform and challenge application • rest of the projects provide middleware • Delivered 1000 motes in 14 kits at 0.5 • mica + general microtracker • 12 Teams demo’d at 1.0 • Demo turned into appln framework at 1.5 • Mica => xbow Dot and Mica2 • Spec feasibility study of OEP 3 • 250 Mote groups, 5,000 units • Mid-Term demo partially shifted to SOCOM demos • Mid-Term demo 7/14 • OEP 2 design for final demo scheduled for this summer nest Retreat

8. Technological “Sweet Spot” • CMOS miniaturization • 1 M trans/$ => tiny (~mm2), inexpensive processing and storage • 1-10 mW active, 1 mW passive (at 1% use 100 mW ave) • Micro-sensors (MEMS, Materials, Circuits) • acceleration, vibration, gyroscope, tilt, magnetic, heat, motion, pressure, temp, light, moisture, humidity, barometric • chemical (CO, CO2, radon), biological, microradar, ... • actuators too (mirrors, motors, smart surfaces, micro-robots) • Communication • short range, low bit-rate, CMOS radios (1-10 mW) • Power • batteries remain primary storage (1,000 mW*s/mm3), fuel cells 10x • solar (10 mW/cm2, 0.1 mW indoors), vibration (~uW/gm), flow • 1 cm3 battery => 1 year at 10 msgs/sec nest Retreat

9. Application Pull • Monitoring Environments • habitat monitoring, conservation biology, ... • Precision agriculture, land conservation, ... • built environment comfort & efficiency ... • alarms, security, surveillance, treaty verification ... • Monitoring Structures and Things • structural response, condition-based maintenance • disaster management • urban terrain mapping & monitoring • Interactive Environments • manufacturing, asset tracking, fleet & franchise • context aware computing, non-verbal communication • assistance • home/elder care • Integrated robotics CENS.ucla.edu nest Retreat

11. Small Technology, Broad Agenda • Social factors • security, privacy, information sharing • Applications • long lived, self-maintaining, dense instrumentation of previously unobservable phenomena • interacting with a computational environment • Programming the Ensemble • describe global behavior, synthesis local rules that have correct, predictable global behavior • Distributed services • localization, time synchronization, resilient aggregation • distributed control • Networking • self-organizing multihop, resilient, energy efficient routing • despite limited storage and tremendous noise • Operating system • extensive resource-constrained concurrency, modularity • framework for defining boundaries • Architecture • rich interfaces and simple primitives allowing cross-layer optimization • Components • low-power processor, ADC, radio, communication, encryption, sensors, batteries nest Retreat

12. The 3 big agendae • Finish the NEST program plan • Identify and complete ~dozen dissertations • Usher the emergence of a sensor-net ecosystem nest Retreat

13. A new retreat format • Two days, Close to home • encourage broader outside participation • Pushed a lot of the technical material into Poster/Demo Session • Opened up the Poster/Demo • Presentation, as well as participation • Discussions looking forward • Panel tonight • Standardization discussion tomorrow nest Retreat
