Algorithm 3 2D UFBS placement process through the k-medoids algorithm with

Y

= 1

1:
input: The set of coordinates of all GMTs $U = {u_{1}, u_{2}, \dots, u_{N}}$
2:
$B_{k}$ = $0, \forall_{k} = 1, 2, \dots, N$
3:
for $i \leftarrow 1$ to N do
4:
$B_{i} = \sum_{j = 1}^{N} {∥ u_{i} - u_{j} ∥}^{2}$
5:
end for
6:
$j^{*} = \underset{i = 1 \dots N}{arg min B_{i}}$
7:
output: The medoid point that the UFBS will be deployed $u_{j^{*}}$ .
