    Abstract: Disclosed are techniques to minimize the electricity consumption of battery powered devices during network discovery and other phases of network operation. Example techniques include efficiently listening for other mains powered and battery powered devices within communication range of the battery powered device by, for example, shortening its listening window depending on how close the time reference maintained by the battery powered device is estimated to be to the time reference used by the other mains powered and battery powered devices within communication range. Other techniques include slowing the rate of listening by the battery powered device when the battery powered device is unlikely to be able to receive discovery messages or is already connected to the network. Other techniques include using knowledge of the network to listen for discovery messages on a channel or channels on which other devices are likely to be transmitting.

    Abstract: Various embodiments disclose a method performed by a first node device in a mesh network that includes identifying a plurality of neighbor node devices that have one or more blocks of a dataset; determining quality scores for respective node devices of the plurality of neighbor node devices; selecting, based on the quality scores, a second node device from the plurality of neighbor node devices; and sending, to the second node device, a first request to receive at least one block of the one or more blocks.

    Abstract: A wireless network includes a plurality of nodes configured to implement an improved discovery process to efficiently and reliably pair with one another with low power consumption. A given node divides time into slots and then performs discovery operations during designated discovery windows. The discovery windows occur periodically but at different times of day. During a given discovery window, nodes attempt discovery using a reduced set of channels that varies from one window to the next, thereby increasing the likelihood that nodes operate on the same channel. Nodes also implement a pairing protocol to coordinate pairing, potentially avoiding situations where all nodes attempt to pair simultaneously. The discovery process may be completed expeditiously, thereby conserving power and extending the operational lifetime of nodes which rely on battery power.

    Abstract: One embodiment of the present disclosure sets forth a technique for resolving beaconing conflicts within a network. The technique includes detecting, by a first node in a network, a first scheduling conflict between a first time when a first beacon is to be transmitted from the first node and a first listening window when a second beacon is expected to be received from a second node in the network; determining, by the first node in response to detecting the first scheduling conflict and based on an expected transmission time for the second beacon and a position of the second node in the network, an alternate listening window during which to listen for a third beacon from the second node; and listening, by the first node, for the third beacon from the second node during the alternate listening window.

    Abstract: One embodiment of the present invention sets forth a technique for performing time synchronization within a network. The technique includes receiving, from a first node in the network and at a first receive time, a first periodic beacon that includes a first network time associated with the first node. The technique also includes determining a second receive time at which a second periodic beacon from the first node is to be received based on the first network time and the first receive time. The technique further includes calculating a first listening window for the second periodic beacon based on the second receive time, a first jitter uncertainty, and a first drift uncertainty, and listening for the second periodic beacon during the first listening window.
