1. A method, comprising:
- determining a need to resynchronize a broadcast and unicast frequency-hopping schedules on a network interface;
in response to the need, soliciting the broadcast schedule from one or more neighbor devices having the synchronized broadcast schedule; and
establishing the unicast schedule for the network interface using communication during the synchronized broadcast schedule.

Abstract
In one embodiment, a device determines a need to resynchronize a broadcast and unicast frequency-hopping schedules on its network interface. In response to the need, the device may solicit the broadcast schedule from one or more neighbor devices having the synchronized broadcast schedule, and then establishes the unicast schedule for the network interface using communication during the synchronized broadcast schedule.

24. A method, comprising:
-
receiving a notice that a neighbor device has an impending de-synchronization of its broadcast and unicast frequency-hopping schedules with an expected time for the impending de-synchronization; awaiting expiration of the expected time; and in response to expiration of the expected time, asynchronously unicasting a message with resynchronization information for the broadcast and unicast schedules to the neighbor device.
