The document discusses Wireless Sensor Networks (WSNs), which consist of numerous sensor nodes that monitor environmental conditions and communicate data through a multi-hop approach. It highlights the components of WSN architecture, including sensor nodes, clusters, and their resource constraints. The document also addresses the challenges of power consumption and communication efficiency within these networks.
