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).
• They are tiny wireless microelectromechanical sensors (MEMS) that can detect everything from light to vibrations

Working Of Smart Dust
• Run by microcontroller
– Determines the task performed by the mote
– Controls power
• Primary constraint of smart dust is volume.
• Most of the time mote if off with only timers running
• When a timer expires, it powers mote to carry out a job , then powers off.

APPLICATIONS
• Smart Dust may be deployed over a region to record data for meteorological, geophysical or planetary research.
• It may be employed to perform measurements in environments where wired sensors are unusable or lead to measurements errors.

Disadvantages
• The main concern is privacy.
• This device can be used to spy on people without their approval.
• The information transmitted through this sensors

CHALLENGING FACTORS
• Sensor nodes breakdown
• The battery management
• Chance of unique addressing would not be feasible.
• Maintenance or fixing of the network would be completely self-governing.

FUTURE SMART DUST
• Smart dust is likely to be the core industries of the future world.
• Tech Giants, Cisco Systems and IBM have started investing millions of dollars to employ smart dusts in systems and networking technology.
• There may be an opportunity to integrate this technology into mobile solutions to transform business processes in the future.
