<p>The present disclosure generally relates to systems and methods for controlling nodes in a communication network, such as a wireless sensor network. In one exemplary embodiment, a node, referred to herein as a“coordinator node,”controls the operation of various nodes, referred to herein as“sensor nodes,”that are configured to monitor various parameters. The coordinator node from time-to-time broadcasts a beacon to the sensor nodes. The beacon can include various information that is used by the sensor nodes for control. In one exemplary embodiment, the beacon includes node-specific information that informs at least some nodes that they are to transition to a sleep state for a certain period of time. Such nodes, based on the beacon, transition to a sleep state, thereby conserving electrical power.</p> |
