Techniques are directed to determining, based at least in part on link quality metric data associated with communication over a link between the first node and a second node, to send an information message to the second node preceded by sending a corresponding polling message to the second node or to send the information message to the second node not preceded by sending the corresponding polling message to the second node. Based at least in part on the determining, a node may send the information message to the second node preceded by sending the corresponding polling message to the second node or sending the information message to the second node not preceded by sending the corresponding polling message to the second node. Overhead associated with polling messages may be reduced.
