This is the most critical layer for power saving. Common protocols like S-MAC or T-MAC use "duty cycling" to turn the radio off when not in use.

Duty Cycling Concept

Routing protocols determine the path data takes through the network. Popular routing protocols used in WSNs include: This is the most critical layer for power saving

Slide 11: Future Directions

A WSN consists of a large number of small, low-power devices called sensor nodes, which are deployed in a specific area to monitor physical parameters such as temperature, humidity, pressure, and motion. These nodes communicate with each other and a central node, called the sink, to transmit data. The sink then forwards the data to a server or a control center for analysis and decision-making. low-power devices called sensor nodes
