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: 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: 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.

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: 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: The disclosure generally relates to using directionality to reduce flooding in a wireless mesh network. In an aspect, a node of the wireless mesh network receives a message for a destination node in the wireless mesh network, determines whether or not the message came from a direction of the destination node, drops the message based on determining that the message came from the direction of the destination node, and forwards the message based on determining that the message did not come from the direction of the destination node.

Abstract: The disclosure generally relates to congestion control, message analysis, and other improvements in a wireless mesh network. For example, according to various aspects, one or more devices in the wireless mesh network may be configured as monitoring nodes and a graph representing a message flow path in at least a portion of the wireless mesh network may be generated based at least in part on information related to one or more messages observed at the monitoring nodes. The graph can then be used to identify a path used to relay a message from at least one destination node to at least one source node (e.g., via one or more intermediate nodes). As such, a time-to-live (TTL) value to be used in messages communicated between the source node and the destination node can be appropriately configured based on a hop count between the source node and the destination node.
