Algorithm 2BLocate Building identification with sensors’ data.

1:
if User is walking then
2:
for $j ⟵ 1 t o 4$ do
3:
$G_{s} (j) ⟵ generate Pattern using G_{f};$
4:
for $k ⟵ 1 t o N$ do
5:
$E_{b i}^{j} ⟵ calculate Euclidean Distance using G_{s} and d B^{k};$
6:
$m E_{b i}^{j} ⟵ get minimum Euclidean distance from E_{b i}^{j};$
7:
end for
8:
$\tilde{E_{b}^{k N}} ⟵ normalize Euclidean distance using m E_{b i}^{j} and N_{b};$
9:
$B_{c} ⟵ get minimum from \tilde{E_{b}^{k N}};$
10:
end for
11:
end if
12:
$B ⟵ finally localize building by removing outliers using B_{c}$ ;
