Utility
Optimized parent and path selection for battery powered devices within a wireless network
9 Jan 24
Techniques for path selection in a network include a first node in a mesh network receiving, from a second node in the mesh network, a first battery life metric for a path through the mesh network, determining a value representing a remaining battery life of the first node, calculating a second battery life metric based on at least one of the first battery life metric for the path or the value representing the remaining battery life for the first node, and transmitting, to a third node in the mesh network, the second battery life metric.

Utility
Secure messaging for outage events
12 Dec 23
Various embodiments disclose a computer-implemented method for sending a message associated with an outage event, comprising, at a first node in a network, receiving a key from a second node in the network, wherein the second node is adjacent to the first node; storing the key in a first memory, wherein the first memory is capable of operating in a low power mode; detecting an outage event; in response to detecting the outage event, operating a first processor in the low power mode; and via the first processor operating in the low power mode: generating a message, securing the message using the key, and sending the message to the second node.

Utility
Techniques for release assistance indication assertion
28 Nov 23
Techniques for transmitting data include identifying data to be transmitted; and in response to a data session window being open: transmitting the data to a transceiver via a transmitter; determining whether there is additional data to be transmitted and determining whether the transmitter has transmitted the data to the transceiver; and in response, instructing the transceiver to end the data session window early and transition to a lower power state.

Utility
Adaptive transmission management based on link latency
21 Nov 23
Various embodiments disclose a method comprising receiving, at a first node, a listening schedule associated with a second node; determining, by the first node, a link latency associated with the second node based on the listening schedule; in response to the first node detecting a frame transmission failure for a frame being transmitted by the first node to the second node, determining, by the first node based on the link latency, a backoff time; and in response to the first node determining that the backoff time has elapsed, the first node retransmitting the frame from the first node to the second node.
