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

Technological “Sweet Spot”

• CMOS miniaturization– 1 M trans/$ => tiny (~mm2), inexpensive processing and storage– 1-10 mW active, 1 W passive (at 1% use 100 W 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

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

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

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
