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 and electrics with miniaturization technology

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

embedded in the same chip Uses RF link for communicating and

transmitting necessary information along with MEMS embedded in the same chip

Components & Specifications

A small, low power computer, with a operating system called Tiny OS.

Sensors Battery Reflectors and transmitters for reflecting the

laser beams And other as per requirements of the dust

Smart Dust Working

Motes are run by Microcontrollers Microcontrollers takes the reading from the

sensors, processes it and stores it It uses optical receiver to receive the

messages from other motes It uses corner cube retro reflector or “Laser”

to transmit sensor data to other motes

Smart Dust working

The batteries are the basic powering devices in the motes

The motes are in sleep mode most of the time with a little consumption of a few micro amps

Counters and timers periodically trigger on the sensors which take the readings, micro-controller transmits them, stores them and the mode again goes to the sleep mode

Applications

Military Smart Office Spaces Environmental Applications Diagnosis of Human Problems Security Purposes Conservation of resources And many more………………..

Smart Military Operations

Can be used to sense enemy movements They can help to collect battlefield

intelligence Can be proved as a weapon against

bioterrorism Can be proved as brilliant spies

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 sensing these elements

Smart Medication

Can assist a Handicap person about the 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 the tiny OS and matching them

AD-HOC networks

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

These ad-hoc networks can be used in various fields where normal links are not possible

Ad- hoc networks can be much cheaper than usual modes of certain applications

Future Goal

In march 2003, this mote named Spec was made in which all the contents of a mote were fitted in less than 5 Sq mm, in less than a dollar. We can imagine motes to be as small as Dust Particles.

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 dust particle.

Extent of miniaturization Can help us to lead a better life, in our own

beautiful environment
