Adaptive polling based on link quality

A method of operating a first node in a network, comprising:

• receiving, from a second node over a link between the first node and the second node, a polling message;
• sending, to the second node over the link, an acknowledgement message corresponding to the polling message;
• receiving, from the second node over the link, a first information message corresponding to the polling message;
• while a link quality corresponding to link quality metric data associated with communication over the link is above a polling disable threshold, receiving, from the second node, a second information message that is not preceded by a corresponding polling message;
• and
• based at least in part on unsuccessfully receiving the second information message that is not preceded by a corresponding polling message, re-receiving, from the second node, the second information message that is preceded by the corresponding polling message.

A node for operation in a network, comprising:

• one or more processors;
• and
• memory coupled to the one or more processors, the memory storing instructions executable by the one or more processors to perform operations comprising:
• determining, based at least in part on link quality metric data associated with communication over a link between the node and another node, to send an information message to the other node preceded by sending a corresponding polling message to the other node or to send the information message to the other node not preceded by sending the corresponding polling message to the other node;
• based at least in part on the determining, sending the information message to the other node preceded by sending the corresponding polling message to the other node or sending the information message to the other node not preceded by sending the corresponding polling message to the other node;
• and
• based at least in part on unsuccessfully communicating the information message to the other node not preceded by sending the corresponding polling message to the other node, resending the information message to the other node, preceded by sending the corresponding polling message to the other node.
