Claim of US Patent No. 10,772,095

1. A method for transmitting unicast messages, the method comprising:determining, by a first node, to transmit a unicast message to a second node;
obtaining, by the first node configured to communicate on a primary time-slotted channel hopping (TSCH) network, a media access control (MAC) address of the second node configured to communicate on the primary TSCH network;
determining whether the first node and the second node are also configured to communicate on a secondary TSCH network; and
in response to determining that the first node and the second node are also configured to communicate on the secondary TSCH network:
offsetting transmission of the unicast message until a second portion of a timeslot for the primary TSCH network;
synchronizing to a channel hopping sequence and frequency of the secondary TSCH network for the second node, and
transmitting, by the first node, the unicast message to the second node on the secondary TSCH network during the second portion of the timeslot.
