Understanding Wireless Sensor Networks: Architecture andd Limitations

A Wireless Sensor Network is a collection of spatially diplomates autonous sensor nodes that cooperatively monitor fizycal or environmental conditions such as temperature, sound, vibration, pressure, motion, or diplomants. Each node typically contains a sensor, microcontroller, radio transceiver, and power source. Data flows from the sensors contribugh intermediate nodes tano a central gateway or base station for processing and analysis.

Common WSN topologies included star, tree, and mesh networks. In large-scale deployments, mesh topologies are preferred because they y provide sumpancy and d someline-healing g capabilities.
