Table 2 Description of variables used in system model

V

Set of vertices.

E

Set of edges (links communication).

e _sd

Specific edge e_sd∈E for vertices s,d∈V.

a _sd

Sum of flows using the edge e_sd.

l _sd

Variable representing the quality of the link e_sd.

f _v

Total of flows sourced in v, by v∈V.

F _sd

Set of flows using the link e_sd.

F

Set of all flows. \(\left (\sum _{v \in V}{f_{v}} = |F| \right)\)

T ^f

Flow rate f∈F.

C _s

Channels assigned to adjacent links of node s∈V.

c _sd

Channel of link e_sd∈E.
