1. A method comprising:

  • receiving, at a first mesh routing node, a prepare-to-change message from a parent node of the first mesh routing node, wherein the prepare-to-change message indicates instructions to prepare to change channels and includes a designated channel;

    forwarding from the first mesh routing node the prepare-to-change message to one or more child nodes of the first mesh routing node;

    receiving a ready-to-change message from the one or more child nodes;

    transmitting a change-to-channel message to the one or more child nodes, wherein the change-to-channel message indicates instructions to switch to the designated channel;

    receiving an acknowledgement message from the one or more child nodes;

    changing, responsive to the acknowledgement message, to the designated channel;

    determining if there is successful connectivity between the first mesh routing node and the one or more child nodes after changing to the designated channel; and

    if there is successful connectivity, transmitting a ready-to-change message to the parent node.
