Time synchronization of mesh network nodes

One or more non-transitory computer readable media storing instructions that, when executed by one or more processors of a first networking device in a mesh network, cause the one or more processors to perform operations comprising:

• determining, based on beaconing time information for a second networking device, an expected receive time for a periodic beacon transmitted by the second networking device;
• determining, based on the expected receive time and at least one of (a) a first amount of jitter uncertainty in timing jitter of the first networking device, (b) a second amount of jitter uncertainty in timing jitter of the second networking device, or (c) an amount of drift uncertainty in a timing error correction between a network time of the first networking device and a network time of the second networking device, a first listening interval for a first periodic beacon from the second networking device;
• and
• listening for the first periodic beacon transmitted by the second networking device during the first listening interval.

A node device in a mesh network, the node device comprising:

• one or more processors;
• and
• a memory storing instructions that, when executed by the one or more processors, cause the one or more processors to perform operations comprising:
• in response to receiving a first periodic beacon from a second node device:
• determining an expected receive time for a second periodic beacon from the second node device based on timing information associated with the first periodic beacon;
• and
• listening for the second periodic beacon during a first listening period determined based on the expected receive time and one or more of uncertainty in an anticipated drift in a timing error correction between a network time of the node device and a network time of the second node device or uncertainty in a timing jitter of the node device or the second node device.
