1. A method, comprising:

  • in a low power and lossy network (LLN) comprising one or more interfaces and a plurality of nodes, preparing, by a sender node, data for transmission to a recipient node via a communication medium;

    determining, by the sender node, if an age value for a current set of transmission parameters associated with the recipient node has exceeded a threshold value;

    in response to determining that the age value has exceeded the threshold value, selecting, by the sender node, a data packet in which to set a transmission parameter request;

    setting, by the sender node, the transmission parameter request in the selected data packet;

    communicating, by the sender node, the data packet comprising the transmission parameter request to the recipient node using a set of base transmission parameters;

    receiving, by the sender node, a transmission parameter response from the recipient node, the response providing updated transmission parameters for the recipient node; and

    updating, by the sender node, the transmission parameters associated with the recipient node based on the updated transmission parameters in the transmission parameter response.
