NOMA and OMA-Based Massive MIMO and Clustering Algorithms for Beyond 5G IoT Networks

Algorithm 1

Step by step working of user clustering.

# NOMA = Non-orthogonal Multiple Access

# SIC = Signal Interference Cancelation

# OMA=Orthogonal Multiple Access

Step 1: total 12 nodes randomly deploy

Step 2: User sends a request to BS for the allocation of resources

Step 3: Request processes to CSI

Step 4: CSI (Channel state information) calculates the distance

Step 4.1: if (distance >100 m)

       {

           Users get NOMA;

       }

Step: After allocation of NOMA (all the strong users will be paired up with weak users) and SIC will be applied to avoid inter user interference.

Step6: else

       {

           Users get OMA;

       }

Step7: end if.
