SMART DUST
Presented by:-
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
