  • Patent number: 10057859
    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.

  • Patent number: 9351267
    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.

  • Patent number: 8982754
    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.

  • Publication number: 20140266592
    Abstract: A system and method for adding a gateway to a first device having a first network connector. An embedded gateway module includes a processor, a memory connected to the processor and first and second network interfaces, wherein the first network connection uses a first network protocol and the second network connection uses a second network protocol. The embedded gateway module is installed in the first device, wherein installing includes sharing the first device's first network connector. The gateway then connects the gateway through the first network to a device manager application at a remote location, connects the gateway module to the second network, installs gateway program data for receiving data from a second device over the second network and storing the received data as channels of data and installs presentation program data for presenting the channel data to applications running on the cloud.

  • Patent number: 8743705
    Abstract: A wireless mesh network test system comprises a plurality of mesh network nodes, each comprising an antenna connection. An antenna network couples the antenna connections of the plurality of nodes, and a plurality of attenuators are distributed in the antenna network such that the attenuators simulate distance between the wireless mesh network nodes.

  • Patent number: 8593991
    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.

  • Patent number: 8547888
    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.

  • Patent number: 8532072
    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 nomination probability associated with 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. Each node then adaptively modifies the probability of nominating itself as a function of the number of beacon signals received from other nodes. 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.

  • Publication number: 20090238109
    Abstract: A method of establishing a qualified route in a mesh network includes transmitting a route-discovery request from a source node such that transmitting includes transmitting the route-discovery request from the source node to at least one intermediate node that is a neighbor node to the source node, receiving the route-discovery request from an intermediate node at the destination node, and updating a route-discovery table for the intermediate node such that the route between the source node and the destination node is the only qualified route.
