An Overview of Wireless Sensor Network (WSN) and its apllications

In the last decade, the evolution and advances in micro, electro-mechanical systems (MEMS) have enabled the development of low cost, low-power , small-sized micro sensors and communicate in short distances Using sensor nodes in monitoring systems have attracted significant attention over the past few years. The Wireless Sensor Networks (WSN) can be applied in numerous ways within our environment, ranging from a general locality, workplace and home.  In this paper, an overview of WSNs and some of WSNs applications.
