where adpKrtRF and adpKhRF are weighting factors;
LCi→j is the link cost in the forward direction and is the link cost in the backward direction;
NumberOfActiveRoutesRF is a number of active routes in the routing table of the node device j that use radio-frequency communications;
MaximumNumberOfActiveRoutes is a maximum number of active routes in the internal routing table of the node device j.
