2.  Introduction
 Fabrication of Smart Dust
 Working
 Major challenges
 Applications
 Advantages & Disadvantages
 Conclusion

3.  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)

6.  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

7.  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.

SMART DUST

9. 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

10. Benefits
 Inspect pipes without
crawling in tight
spaces.
 No need to remove
insulation to inspect
pipe

11.  Small Size
 Better Connectivity
 Low Cost

12.  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.

13. 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.
