A Presentation OnSMART DUST

CONTENTS Introduction Fabrication of Smart Dust Working Major challenges Applications Advantages & Disadvantages Conclusion

INTRODUCTION Smart Dust is a self-contained network of tiny motes each

having the capability of sensing and monitoring the environment conditions.

Smart Dust concept has been credited to researchers at the University of California, Bekerley in 1997 by Prof. Kris Pister.

They contain sensors which have the computational capability  They can communicate with a base station or with other motes

depending on the application. The transmission is carried out by microscopic devices known

as micro electromechanical system (MEMS)

FABRICATION OF SMART DUST

WORKING

Smart dust motes run by a microcontroller.

Microcontrollers consist of tiny sensors for recording various types of data.

Sensors run by timers.  Data is sent to the base controlling

station Corner Cube Retro-Reflectors (CCR)

built using MEMS technique

MAJOR CHALLENGES

It is difficult to fit all these devices in a small Smart Dust both size wise and Energy wise.

As the devices are so small, batteries present a massive addition of weight.

APPLICATIONS

Environmental protection Habitat Monitoring In hospitals In military Security Virtual keyboards

Circulatory Net

SMART DUST

Virtual Keyboard

FOREST FIRE DETECTION

IMPLEMENTATION Drop a smart dust from an

airplane Motes self-organize into a

network

USAGE A mote that detects a fire

notifies central monitoring station

The mote location is the approximate location of the fire

SPOTTING PIPE CORROSION

Benefits Inspect pipes

without crawling in tight spaces.

No need to remove insulation to

inspect pipe

ADVANTAGES

Small Size Better Connectivity Low Cost

DISADVANTAGES

The main concern is privacy. Because it is so tiny, this device can be used to spy on people without their approval.

Another concern is the security of the information transmitted through this sensors. Like in any other computer, hackers can brake into the system and steal or modify important data.

CONCLUSION

There are many ongoing researches on Smart Dust, the main purpose of these researches is to make Smart Dust mote as small as possible and to make it available at as low price as possible.
