Abstract
In one embodiment, a device in a network receives a time-slotted channel hopping (TSCH) communication schedule. The TSCH communication schedule is divided into a plurality of macrocells, each macrocell comprising a plurality of TSCH cells. The device receives a packet from a routing protocol child node of the device during a particular macrocell of the TSCH communication schedule that is associated with propagation of the packet through the network. In response to receiving the packet, the device claims a token associated with the particular macrocell that authorizes the device to transmit during one or more cells of the macrocell. The device transmits the received packet to a second node in the network during the authorized one or more cells of the particular macrocell.
