Algorithm 3: NSR deployment through hybrid PROMETHEE-II and SLE

1:
Input: NSR deployment
2:
Output: $S P A$
3:
Set,
- $C P U_{s e r v e d, i} = 0$ and $a_{i j, s e r v e d} = 0, \forall N_{P} (i)$ of $G_{P}$ and
- $B W_{i j, s e r v e d} = 0, \forall E_{P} (i, j)$ at $t = 0$
4:
while $t < T_{m a x}$ do
5:
Get $G_{N S R}$
6:
Call Algorithm 1 for Node Allocation
7:
if NSR node allocation unsuccessful then
8:
Increment $N S R_{u n s u c c e s s f u l} (t)$
9:
else
10:
Increment $N S R_{s u c c e s s} (t)$
11:
Call Algorithm 2 for SLE
12:
Calculate $N S R_{r e v e n u e} (t)$ and $P S I_{c o s t} (t)$
13:
end if
14:
Increment t
15:
end while
16:
Calculate $P_{N A R}$ and $P_{R E}$
