1. A method comprising:
communicating, by a first node and via a communication link between the first node and a second node, with the second node according to a first modulation scheme and, based at least in part on the first modulation scheme, determining first communication metric data;
communicating, by the first node and via the communication link between the first node and the second node, with the second node according to a second modulation scheme and, based at least in part on the second modulation scheme, determining second communication metric data; and
determining, by the first node, link quality metric data associated with the communication link, the link quality metric data associated with the communication link being based at least in part on the first communication metric data and the second communication metric data,
wherein:
the determining the link quality metric data includes, for the first modulation scheme and the second modulation scheme:
calculating an expected transmission (ETX) at a defined epoch; and
applying a filtering calculation to the ETX,
the determining the link quality metric data associated with the communication link includes applying a first weighting coefficient to the first communication metric data and a second weighting coefficient to the second communication metric data,
the first weighting coefficient is based at least in part on a number of transmission attempts made according to the first modulation scheme; and
the second weighting coefficient is based at least in part on a number of transmission attempts made according to the second modulation scheme.
