where:
adpKqRF et adpKdcRF are weighting factors;
adpHighLQIValueRF and adpLowLQIValueRF are threshold values;
LQIRF is a value representing a quality of a radio-frequency link in the forward direction between the node devices i and j;
DutyCyclePenalty is a value representing a degree of use of the radio frequency link already reached with respect to an authorised maximum.
