Tiny dust size device that combine sensing, computing, wirelesscommunication capabilities and autonomous power supplywithin volume of only few millimeters.

Also called Motes

These motes have memories,

microprocessor, radio receiverand transmitter

So small and light in weight

that they can remain

suspended in the environment.

History

Conceived by Dr. Kristofer s.j. Pister of UC Berkeley

Funded by DARPA (Dept. of Defense)Kris Pister



5/14

Basic ideaThe mote concept creates a new way of thinking about

computers, but the basic idea is pretty simple:

1. The core of a mote is a small, low-cost, low-power computer.

2. The computer monitors one or more sensors , includingsensors for temperature, light, sound, position, acceleration,vibration, etc.

target/goal1. Demonstrate useful/complex integration in

1 mm3

2. Autonomous sensor node (mote) in 1 mm33. MAV delivery

4. Thousands of motes

Technologies used

Smart Dust combines the following three technologies:

1. Digital Circuitry

2. MEMS (Micro-Electro-Mechanical Systems)

3. RF (Radio Frequency) Wireless CommunicationTechnology

orFSOT



10/14

Applications1. Environmental monitoring:

2. Monitor power consumption of householdappliances:

3. Measuring structural integrity of a building or anyother structure:

4. Military Application

5. Habitat monitoring:



11/14

advantages Physical attributes:

Small and lightweight

Low power consumption

Ad-hoc networking capabilities:

Networking functions are seamless and automatic

Multiple networks can be in use simultaneously

Data transmission capabilities:

On-board data acquisition supports many missions

Data can be carried through network to commandcentres

Ubiquity and redundancy in use:

Multiple motes can be available on every device/person Motes can be strewn in large numbers



12/14

dark side Low Throughput ( < 10 Kbps ) :

Suited for data monitoring, not real-time audio

Power Source :

RF communications circuits drain a lot of power Need advancement in battery technology

Size : Many components -> difficult to reduce size

Cost

Current motes cost between $5 - $10 each

Intrusive probes

A number of political, environmental, health and privacy relatedquestions
