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 mesh network includes a child node coupled to a parent node. The parent node transmits time sync beacons that indicate a time slot number and a start time for a current time slot. The child node receives the time sync beacons and determines a delta between the current time slot number of the child node and the current time slot number of the parent node. The child node also computes an offset between a start time of the current slot of the child node and the start time of the current slot of the parent node. The child node reports the delta and the offset to the parent node. Based on the delta and the offset, the parent node determines when, and on what channel, the child node is predicted to be receiving transmissions, and then schedules transmissions to the child node accordingly.
