Wireless Sensor Networks enable future IoT revolution, smart cities and detecting, classifying and tracking Military threats

A wireless sensor network (WSN) is a wireless network consisting of spatially distributed autonomous devices using sensors to monitor physical or environmental conditions. The self-powered nodes are equipped with sensors of light, sound, heat, pressure, e.t.c, communicating components and data processing that gather information or detect special events and send the data to the base station to be processed.

The emergence of small, low-cost, and low-power sensor technologies like microelectromechanical system (MEMS) sensors, on-board signal processing and wireless communication all integrated on a single chip (system on a chip (SoC)), has stimulated great interests in the utilization of Wireless sensor networks in a wide variety of critical applications.
