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.
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
