Smart Dust An Introduction

Miniaturization

MEMS Micro-electro-mechanical

Systems.

Radio transmitters and receivers

Tiny Computerized Sensors

Single units known as MOTES

Smart Dust History

Conceived in 1998 by Dr. Kris Pister of

University of California Berkeley

Funded by DARPA Defense

Advanced Research Project Agency

Powering Issue

Smart Dust Overview

Merger of Computers, Mechanics andelectrics with miniaturizationtechnology

Its core is small, low power Computer This Computer monitors the sensors

embedded in the same chip

Uses RF link for communicating andtransmitting necessary informationalong with MEMS embedded in thesame chip


6/20

Components & Specifications

A small, low power computer, with a

operating system called Tiny OS. Sensors

Battery

Reflectors and transmitters forreflecting the laser beams

And other as per requirements of the

dust

Smart Dust Working

Motes are run by Microcontrollers

Microcontrollers takes the readingfrom the sensors, processes it and

stores it It uses optical receiver to receive the

messages from other motes

It uses corner cube retro reflector orLaser to transmit sensor data to

other motes

Smart Dust working

The batteries are the basic poweringdevices in the motes

The motes are in sleep mode most of

the time with a little consumption of afew micro amps

Counters and timers periodicallytrigger on the sensors which take the

readings, micro-controller transmitsthem, stores them and the mode againgoes to the sleep mode

Applications

Military

Smart Office Spaces

Environmental Applications

Diagnosis of Human Problems

Security Purposes

Conservation of resources

And many more..


12/20

Smart Military Operations

Can be used to sense enemymovements

They can help to collect battlefield

intelligence Can be proved as a weapon against

bioterrorism

Can be proved as brilliant spies


13/20

Smart Environment

Can be used as seismic sensors Can be sewn in clothes to sense the

working environment and change in it,

so that the user can get better off it Can be used to identify the pollutants

present in the environment

Can make our life better by sensingthese elements


14/20

Smart Medication

Can assist a Handicap person aboutthe paths

Can assist in detecting and destroying

tumor cells in the body Can help to identify Various type of

diseases for whom the definitions are

not yet given by defining them in thetiny OS and matching them


15/20

AD-HOC networks

Smart dust can be used to form Ad-hoc networks, which can use radio linkto transmit data

These ad-hoc networks can be usedin various fields where normal linksare not possible

Ad- hoc networks can be muchcheaper than usual modes of certainapplications


16/20

Future Goal

In march 2003, thismote named Spec wasmade in which all thecontents of a mote

were fitted in less than5 Sq mm, in less thana dollar. We canimagine motes to be

as small as DustParticles.


17/20

Future Goals

Weather/seismological monitoring

Internal spacecraft monitoring

Land/space comm. networks

Chemical/biological sensors

Weapons stockpile monitoring

Defense-related sensor networks

Conclusion

Smart dust is the power of pc in a dustparticle.

Extent of miniaturization

Can help us to lead a better life, in ourown beautiful environment
