INTRODUCTION
  • What is Smart Dust?
  • What are its components?
  • How it is implemented?
  • What are its applications?
  • What are its advantages?

3
What is smart dust?
  • Smart Dust is a self-contained network of tiny
    motes each having the capability of sensing and
    monitoring the environment conditions.
  • First devoloped by professor Kris Pister at the
    University of California, Berkeley

4
Motes
  • They are tiny particles which will be around the
    size of a grain of sand
  • They contain sensors which have the computational
    capability, power supply, programmable
    microprocessor, analog circuitry
  • A network of these motes leads to SMART DUST
    project
  • Can communicate with a base station or with other
    motes depending on the application

5
Base Station Transceiver
  • It is used to retrieve the data stored by the
    motes
  • It consists of a laser source and a receiver
  • Enables communication with the motes

Requirements
  • Power
  • Sensors
  • Efficient Communication

8
Components
  • Sensors
  • Corner Cube Retro-reflector (Passive Transmitter)
  • Active Transmitter
  • Photo detector
  • Solar cell, DSP, Analog I/O, Power Capacitor,
    Thick Film Battery

Implementation
  • Sensors monitors the atmosphere
  • Communication can be of two types
  • Active Communication and Passive
  • Communication

11
Active Communication
  • It consists of an onboard laser, collimating
    lens, beam steering mirror
  • Active Communication can be used for mote-to-mote
    communication if required
  • High power Density but high power consumption

12
Passive Communication
  • Corner Cube Retro-Reflector
  • Base Station with a Receiver and a laser source
  • Enables Bi-directional Communication
  • Line of Sight required

13
Implementation ( Cont d )
  • It consists of a photo detector in order to
    detect the signal and receive it
  • The DSP (digital signal processor) is used to
    process signals received.

14
Power
  • It consists of a lithium battery
  • Key constraint in the design of a mote
  • The battery and Capacitor can store
    upto1J/cubic mm and 10mJ/ cubic mm
  • It contains a timer which monitors the operation
    of a mote

15
Applications
  • Military Applications
  • Medical Applications
  • Climate monitoring
  • Virtual Keyboard
  • Structure Maintenance

16
Advantages
  • Good Functionality
  • Small Size
  • Better Connectivity
  • Low Cost
