What is Wireless Sensor Network?<\/a><\/p>\n\n\n\n

Introduction<\/span><\/mark><\/strong><\/h2>\n\n\n\n

A wireless sensor network <\/strong>(WSN) is a wireless network consisting of spatially distributed autonomous devices using sensors to cooperatively monitor physical or environmental conditions, such as temperature, sound, vibration, pressure, motion or pollutants, at different locations.<\/p>\n\n\n\n
