Algorithm 1: A “CCF-based adaptive fuzzy c-means clustering” algorithm

Input: input ${\mathrm{N}}_O=\{{\mathrm{N}}_{O_1}, {\mathrm{N}}_2, {\mathrm{N}}_{O_3} \dots . {\mathrm{N}}_{O_i\}}$ the group of network nodes, SINR, level of congestion, and survivability Output: clustered data

Begin    for $j= \mathrm{t}\mathrm{o} {\mathrm{N}}_{\mathrm{0}}$. do       For belonging to cluster I, Node $j$. receives coefficient $v_{ij}$    End for       Repeat    for $i=1 \mathrm{to} k$. do          Using condition (8), determine each cluster’s centroid (9)    End for    Repeat from Begin: Until the stop, the condition is met End
