  • Patent number: 11216051
    Abstract: This disclosure provides systems, methods and apparatus for smart sockets in a communication network. A smart socket can be implemented to monitor one or more power quality characteristics of a power supply providing energy to the smart home environment. Smart sockets implemented to monitor power quality characteristics can sense when power fluctuations are present in the power supply, and shut down connected devices to prevent damage. A plurality of coordinating smart sockets can be implemented to optimize power utilization when the smart home environment is operating on backup power, during low electricity tariff periods, or when operating on a renewable energy source. The plurality of coordinating smart sockets can be implemented to autonomously schedule tasks based on a context of operation of other devices in the smart home environment. The plurality of coordinating smart sockets can be implemented to achieve configurable energy targets for the smart home environment.

  • Patent number: 11166156
    Abstract: Disclosed are techniques for establishing an encrypted connection between a first node and a second node in a wireless mesh network. In an aspect, the first node receives, from a provisioner node in the wireless mesh network, a first value encrypted with a device-specific encryption key known only to the first node and the provisioner node, wherein the second node receives, from the provisioner node, the first value encrypted with a second device-specific encryption key, generates a friendship-specific encryption key based on the first value, an identifier of the first node, and an identifier of the second node, wherein the second node generates the friendship-specific encryption key, sends, to the second node, a first message encrypted with the friendship-specific encryption key, and receives, from the second node, a second message encrypted with the friendship-specific encryption key.

  • Patent number: 10917829
    Abstract: Methods, systems, and devices for wireless communications in a mesh network are described. During a path establishment procedure, a source device may broadcast a path request message, which may be forwarded (e.g., broadcast) by intermediate devices downstream through the mesh network to a destination device. Devices, starting with the destination device and continued upstream through intermediate devices along a path to be established, may feedback path response messages to establish a path between the destination device and the source device. Path response messages transmitted upstream through the mesh network may each include a handover address of a backup intermediate device. Therefore, upon reception of a path response message, an intermediate device selected for path establishment to a destination device may identify a handover address of a backup intermediate device. The intermediate device may perform a handover procedure with the backup intermediate device if a handover condition has been satisfied.

  • Publication number: 20200413334
    Abstract: A low power node (LPN) may identify one or more message repetition configurations (e.g., for one or more messages or payloads to be transmitted by the LPN, according to respective message repetition configurations) and may leverage a friend device for transmission operations associated with the message repetitions. For example, an LPN may indicate a payload (e.g., data or message information) and a corresponding message repetition configuration to a friend device (e.g., which may be wall powered and have access to more power resources), such that the friend device may perform transmission repetitions on behalf of the LPN. As such, upon conveying such payload and message repetition configuration information to the friend device, the LPN may enter a low power state (e.g., an idle mode, a sleep state, a discontinuous reception state, etc.) while the friend device performs transmission operations on behalf of the LPN (e.g., effectively conserving LPN power resources).

  • Patent number: 10880807
    Abstract: A device in a mesh network may select a relay path for use based on the power resources available to the devices forming the relay path. For example, if there are multiple relay paths available for selection, the device may choose a relay path that has the lowest quantity of devices that are operating on battery power. The device may determine the quantity of battery-powered devices associated with a path based on power information included in one or more messages received from one of the devices forming the path. After selecting the relay path, the device may transmit a response message to an intermediary device forming the relay path. The intermediary device may, in some examples, be a device that transmitted a message including the power information.

  • Publication number: 20200146088
    Abstract: Systems and methods for initialization vector (IV) index recovery for a Bluetooth special interest group (SIG) mesh network include a receiving device in a first node of the mesh network, wherein the receiving device retrieves, from a secure network beacon (SNB), a retrieved IV index. If the retrieved IV index is greater than a current IV index of the receiving device by at least a value of two, the receiving device enters a recovery mode for recovering a correct IV index. In the recovery mode, the receiving device may receive the correct IV index from a Bluetooth device, if available, over a secure link, or from a trusted device in a second node of the mesh network. The mesh network may also include a monitoring device to provide the correct IV index to the receiving device.
