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

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
