a presentation on 6G technology

1. A presentation on
SMART DUST
Presented by:-

2. Smart Dust – An Introduction
 Miniaturization
 MEMS – Micro-electro-mechanical Systems.
 Radio transmitters and receivers
 Tiny Computerized Sensors
 Single units known as MOTES

4. 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

5. 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

6. 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

9. 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

10. 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

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

12. 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

13. 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

14. 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

15. 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

16. 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.

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

18. 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
