Abstract: One embodiment of the present invention sets forth techniques for evaluating connections between nodes in a mesh network. The techniques include determining, by a first node, a number of messages received by the first node from a second node during a period of time, the period of time including a number of listening windows during which a message is expected to be received from the second node; determining, by the first node based on the number of messages received and the number of listening windows, a received message success rate associated with the second node; selecting, by the first node, the second node from a plurality of neighbor nodes based on the received message success rate; and transmitting, by the first node, a first message to a target destination via the second node.

Abstract: One embodiment of the present invention sets forth a technique for communicating within a network. The technique includes receiving, by a first node in a mesh network at a first receive time, a first beacon from a second node in the mesh network, the first beacon including a first network time associated with the second node; determining, by the first node, a first transmission time of a first unicast message to the second node based on (a) the first receive time, (b) the first network time, and (c) a unicast interval between consecutive unicast listening times on the second node; and transmitting, by the first node, the first unicast message to the second node at the first transmission time.

Abstract: Various embodiments disclosed herein provide communication techniques using forced forward addressing. In various embodiments, a method includes receiving, by a first node of a mesh network, a first unicast message from a second node, wherein the first node is coupled to one or more of child nodes that are neighbor nodes to the first node; determining, by the first node, that a destination address of the first unicast message is a forced forward address; and in response to determining that the destination address is a forced forward address, forwarding, by the first node, the first unicast message to the one or more of child nodes by transmitting respective second unicast messages to the one or more of child nodes.

Abstract: Techniques for performing time synchronization within a network include a method comprising: determining, by a first node, a receive time at which a periodic beacon from a second node is expected to be received based on timing information associated with the second node; determining, by the first node, a first listening window for the periodic beacon based on the receive time and one or more of a drift uncertainty associated with an anticipated drift in a correction of a timing error between the first node and the second node or a jitter uncertainty associated with timing jitter in the first node or the second node; and listening, by the first node, for the periodic beacon during the first listening window.

Abstract: One embodiment of the present invention sets forth a technique for performing time synchronization within a network. The technique includes detecting a first scheduling conflict between a first transmission time associated with a first periodic beacon from a first node in the network and a first listening window associated with receiving a second periodic beacon from a second node in the network. The technique also includes determining a first alternate transmission time for the second periodic beacon based on a second transmission time associated with the second periodic beacon and a position of the second node in the network and calculating a second listening window associated with transmission of the second periodic beacon from the second node at the first alternate transmission time. The technique further includes listening for the second periodic beacon during the second listening window.

Abstract: Various embodiments set forth a method comprising detecting, by an access point, that the access point has obtained network connectivity after a first reboot event; in response to detecting that the access point has obtained network connectivity after the first reboot event: determining, by the access point, a first amount of time between a first reboot time associated with the first reboot event and a second reboot time associated with a second reboot event that occurred prior to the first reboot event; updating, by the access point, a reboot time metric associated with the access point based on the first amount of time; and transmitting, by the access point, the reboot time metric to one or more nodes of a mesh network.
