Patent ID: 11916683
Assignee: LANDIS+GYR TECHNOLOGY, INC.
Field: Digital communication (Electrical engineering)
Classification: CPC H | IPC H

Claim 0:
1. A node, comprising:
a processor;
a wireless transceiver communicatively coupled to the processor and configured to receive communications based on a channel hopping timing interval and a channel hopping sequence; and
a memory communicatively coupled to the processor and comprising instructions that are executable by the processor to cause the processor to:
store a broadcast channel hopping timing interval and a broadcast channel hopping sequence;
store a channel hopping timing and a channel hopping sequence for each of a plurality of tracked neighbor nodes;
determine whether a destination node for a unicast message corresponds to any of the plurality of tracked neighbor nodes;
based on a determination that the destination node does not correspond to any of the plurality of tracked neighbor nodes, determine (i) a next broadcast dwell interval based on the broadcast channel hopping timing interval and (ii) a next broadcast channel based on the broadcast channel hopping sequence;
based on the determination that the destination node does not correspond to any of the plurality of tracked neighbor nodes, determine to transmit the unicast message to the destination node during the next broadcast dwell interval;
at a start of the next broadcast dwell interval, listen for broadcast traffic; and
back off sending of the unicast message to the destination node when broadcast traffic is detected during the next broadcast dwell interval.
