Abstract:
1. A method comprising: determining a wakeup beacon schedule for a node of a mesh network, the determining including: having the node enter a power-saving state, wherein during the power-saving state, the node has insufficient power to permit communications with the one or more peer nodes of the mesh network; in accordance with the wakeup beacon schedule, having the node i) exit the power-saving state and ii) enter into a communication state, wherein during the communication state, the node is permitted to communicate with the one or more peer nodes of the mesh network; receiving, at the node, one or more wakeup beacons from the one or more peer nodes of the mesh network, each of the one or more wakeup beacons indicating whether or not data is waiting to be received by the node; if at least one of the one or more wakeup beacons indicates data is waiting to be received by the node, maintaining the node in the communication state to permit the node to receive the data indicated by the one or more wakeup beacons; and if none of the one or more wakeup beacons indicates data is waiting to be received by the node, having the node re-enter the power-saving state.
