Abstract: Devices, systems, and techniques for a synchronized network for battery backup are described herein. A network device can establish a synchronized sleep schedule with the network while in a mains-power mode of operation. The network device can transmit data in the mains-power mode without regard for a transmission window of the synchronized sleep schedule. The network device can detect an interruption of mains power to itself and transition to a low-power mode of operation. The network device can then transmit data in the low-power mode, restricting data transmission to the transmission window of the synchronized sleep schedule.

Abstract: A set sleep period is coordinated among a plurality of mesh network nodes to conserve power. A controller is synchronized with an existing wireless mesh network by sending a network synchronization signal from the controller indicating that sleep timing information is lost, and receiving a reply from one or more wireless mesh network nodes within the existing wireless mesh network comprising sleep timing information for the wireless mesh network.

Abstract: A set sleep period is coordinated among a plurality of mesh network nodes to conserve power. A neighbor wireless mesh network node in proximity to a second node to be added to the mesh network is actuated, causing the neighbor wireless mesh network to be woke from a sleep state. The second node is added to the wireless mesh network by exchanging data with the neighbor wireless mesh network node to join the network.

Abstract: A system and method of operating a wireless network having a plurality of nodes. Each node determines whether to replace the beacon node. When a node determines that the beacon node is to be replaced, the node determines whether it should nominate itself as a potential replacement beacon node. The decision whether to nominate itself as a potential replacement beacon node is a function of a random number generated by the node. If the node determines that it should nominate itself as a potential replacement beacon node, the node sends out one or more beacon signals. Beacon signals are received by potential replacement nodes and, if the potential replacement beacon node has received a beacon signal from a higher ranking potential replacement beacon node, the node removes itself as a candidate for the replacement beacon node.

Abstract: A set sleep period is coordinated among a plurality of mesh network nodes to conserve power, and a temporarily reduced sleep period is coordinated among the plurality of nodes to facilitate mesh network node service or installation activity. The reduced sleep period comprises scheduling a period of time during which the sleep period is reduced, or reverting from the temporarily reduced sleep period to the original set sleep period after predetermined period of time. Temporarily reducing the sleep period includes distributing a message throughout the mesh network when the mesh network nodes are awake.
