In one embodiment, a device in a network determines a first channel hopping schedule for the device to receive unicast communications from one or more neighbors of the device. The first channel hopping schedule differs from channel hopping schedules used by the one or more neighbors to receive unicast communications. The device determines a second channel hopping schedule for the device that includes a common channel that is common to the device and the one or more neighbors at any given point in time, wherein the second channel hopping schedule is self-generated by each of the device and the one or more neighbors. The device switches from the first channel hopping schedule to the second channel hopping schedule, in response to a network event. The device causes a particular neighbor to join the network using the second channel hopping schedule. |
