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

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

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

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

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

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

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.

Future Goals
Weather/seismological monitoring
Internal spacecraft monitoring
Land/space comm. networks
Chemical/biological sensors
Weapons stockpile monitoring
Defense-related sensor networks
