Wireless sensor networks

The rapid progress of wireless communication and embedded micro-sensing microelectromechanical systems (MEMS) technologies has made wireless sensor networks (WSN) possible. A WSN consists of many inexpensive wireless sensors, which are capable of collecting, storing, processing environmental information, and communicating with neighboring nodes. In the past, sensors are connected by wirelines. With the development of ad-hoc networking technologies, tiny sensors can communicate through wireless links in a more convenient manner.

Research and commercial interest in the area of wireless sensor networks are currently growing exponentially. They are expected to become a radical innovation similar to the Internet.
