Wireless Sensor Networks

What are wireless sensor networks (WSNs)?

A wireless sensor network (WSN) is a wireless network using sensors to cooperatively monitor physical or environmental conditions.

Networks of typically small, battery- powered, wireless devices (often MANY, sometimes heterogeneous).

• On-board processing,

• Communication, and

• Sensing capabilities.
