Dynamic frame selection when requesting tone map parameters in mesh networks |
摘要 |
In a multiple interface, low power and lossy network comprising a plurality of nodes, a sender node dynamically selects a data packet for setting a transmission parameter request in response to determining that an age value for a set of transmission parameters associated with a recipient device has expired or is expiring. The sender node selects an desired data packet for sending a transmission parameter request and transmits the selected data packet to the recipient device. The sender node receives a transmission parameter response from the recipient node comprising updated transmission parameters for that recipient node and then updates the current transmission parameters associated with the recipient node accordingly. |

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. |
