ABSTRACT
Advances in hardware technology have enabled very compact, autonomous and mobile nodes each having one or more sensors, computation and communication capabilities, and a power supply. The Smart Dust project is exploring whether an autonomous sensing, computing, and communication system can be packed into a cubic millimeter mote to form the basis of integrated massively distributed sensor networks. It focuses on reduction of power consumption, size and cost. To build these small sensors, processors, communication devices, and power supply, designers have used the MEMS (Micro electro mechanical Systems) technology. Smart Dust nodes otherwise known as “motes” are usually of the Size of a grain of sand and each mote consists of:
1. Sensors
2. Transmitter &receiver enabling bidirectional wireless communication.
3. Processor sand control circuitry
4. Power supply unit
Using smart dust nodes, the energy to acquire and process a sample and then transmit some data about it could be as small as a few nano Joules. These dust motes enable a lot of applications, because at these small dimensions, these motes can be scattered from aircraft for battle field monitoring or can be stirred into house paint to create the ultimate home sensor network.
INTRODUCTION
The current ultramodern technologies are focusing on automation and miniaturization. The decreasing computing device size, increased connectivity and enhanced interaction with the physical world have characterized computing's history. Recently, the popularity of small computing devices, such as hand held computers and cell phones; rapidly flourishing internet group and the diminishing size and cost of sensors and especially transistors have accelerated these strengths. The emergence of small computing elements, with sporadic connectivity and increased interaction with the environment, provides enriched opportunities to reshape interactions between people and computers and spur ubiquitous computing researches. Smart dust is a tiny dust size device with extra-ordinary capabilities. Smart dust combines sensing, computing, wireless communication capabilities and autonomous power supply within volume of only few millimeters and that too at low cost. These devices are proposed to be so small and light in weight that they can remain suspended in the environment like an ordinary dust particle. These properties of Smart Dust will render it useful in monitoring real world phenomenon without disturbing the original process to an observable extends. Presently the achievable size of Smart Dust is about 5mm cube, but we hope that it will eventually be as small as a speck of dust. Individual sensors of smart dust are often referred to as motes because of their small size. These devices are also known as MEMS, which stands for micro electro-mechanical sensors.
