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.

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.

Abstract: Disclosed are techniques for detecting a security threat in a wireless mesh network. In an aspect, a monitoring device in the wireless mesh network detects a first message transmitted by a source node in the wireless mesh network to a destination node in the wireless mesh network via at least one relay node in the wireless mesh network, collects information from the first message as it is transmitted in the wireless mesh network, determines that the first message has been corrupted based on analysis of the information from the first message, and detects the security threat in the wireless mesh network based on the first message being corrupted.

Abstract: Methods, systems, and devices for controlling mesh network devices are described. The method includes receiving, by an automation device, a first message from a control device, adding, by the automation device, the identifier of the first user device to a priority list of the automation device based on receiving the first message, and controlling, by the automation device, access to operations of the automation device based on the identifier in the priority list after adding the identifier of the first user device. In some cases, the first message includes an identifier of a first user device and an add command.

Abstract: Methods, systems, and devices for secure recovery from full replay protection lists are described. The method includes receiving, at a second device from a first device in a wireless mesh network, a first message indicating that a replay protection list (RPL) of the first device has reached a defined capacity, determining whether the first device is configured with a fixed RPL or a dynamic RPL based on the first message or a provisioning message received before the first message, sending, from the second device, a second message indicating at least one of an increase of a capacity of the RPL or a set of source addresses to be included in or removed from the RPL based on determining whether the first device is configured with the fixed RPL or dynamic RPL, and receiving, from the first device, an indication that the RPL has been updated based on the second message.

Abstract: A method for secure path discovery in a mesh network at a destination device is disclosed. The method includes receiving a path discovery request from an originator device and selecting a path selection in response to the path discovery request. The method also includes transmitting the path selection to the originator device and receiving a random seed from a provisioner device. The method also includes generating an authentication code based on the random seed, transmitting an authentication code message to an originator device and receiving communications from the originator device only if the originator device receives a verification response message from the provisioner device which confirms that the destination device has been verified.

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.

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.
