Algorithm 1: Fuzzy C-Means

input: The geographical coordinates of the devices, the desired number of clusters M and the error stop criterion

ϵ

output: The final fuzzy c-partitioned matrix

U_{i j}^{r}

, the geographical coordinates of the gateways, the final Euclidean distance matrix, and the objective function
