Future mobile wireless sensor network technology, such as smart dust, may seem like science fiction, but it is moving from the research lab to the enterprise. What is smart dust? This is a new technology that could shape our future in ways never imagined. Think about the computer you use and think about that same computer, scaled to the dimensions of an American neighborhood. That's pretty much what smart dust is, also known as microelectromechanical sensors (MEMS). Smart dust has four basic subsystem requirements: power, compute, sensor, and communication. The initial idea of ​​Smart Dust was to miniaturize the sensors and unite them with wireless communication technology to form network devices capable of providing a stream of data from each of the sensors and integrating them to collect, analyze and store data and create an intelligent response. Applications of smart dust include tracking enemy movements in military operations, battlefield surveillance, transportation monitoring, factories, instruments, climate control, environmental monitoring, security and l building automation, security systems, etc. In this research, I want to focus on the architecture and working of Smart Dust, future trends, various applications of Smart Dust technology and some of the issues related to Smart Dust.IntroductionCurrent technologies focus on automation and miniaturization . The technology is characterized by the reduction in size and shape of computing devices, increased connectivity, and improved interaction with the physical world. Recently, the popularity of computers and cell phones, the growth of the Internet, and the decreasing size and cost of sensors have accelerated these trends.
