The emerging field of wireless sensor networks combines sensing, computation, and communication executed with tiny devices. Through advanced mesh networking protocols, these devices can form a sea of connectivity that extends the reach of cyberspace out into the physical world. While the capabilities of any single device are minimal, the composition of hundreds of devices offers radical new technological possibilities.
Wireless sensor networks (WSN) represent an emerging set of technologies that will have profound effects across a range of medical, industrial, scientific and governmental applications. A wireless sensor network is made up of a group of sensor nodes or devices. Each device possesses the ability to monitor some aspect of its environment, and each is able to communicate its observations through other devices to a destination where data from the network is gathered and processed.
