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. 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 Goal

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

19. Any Questions???
