Wireless Sensor Networks


Wireless Sensor Networks (WSNs) are networks of small, low-power devices called sensors that are equipped with wireless communication capabilities. These sensors are distributed over a geographical area and are used to monitor physical or environmental conditions such as temperature, humidity, pressure, sound, and motion. The data collected by these sensors is transmitted wirelessly to a central location where it is processed and analyzed. WSNs are used in a variety of applications such as environmental monitoring, healthcare, agriculture, and industrial automation. The design of WSNs involves several challenges such as energy efficiency, scalability, and security.
