Various aspects of the present disclosure generally relate to wireless communication. In some aspects, an assisting wireless device may track a first retransmission metric that is based on a number of retransmitted packets that the assisting wireless device received from a source device. The assisting wireless device may receive, from a sink wireless device, an acknowledgement assistance request indicating a second retransmission metric for the sink wireless device. The assisting wireless device may transmit, to the sink wireless device, a response to the acknowledgement assistance request based on respective values of the first retransmission metric and the second retransmission metric. Numerous other aspects are described.

Assisted acknowledgement for wireless streaming

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.

Secure path discovery in a mesh network

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.

Smart socket power monitoring and coordination

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.

Path handover in Bluetooth mesh routing

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.
