Abstract: The article computes the data rate of RIS where the source takes power from wind. The harvested power is employed to broadcast data to secondary non-orthogonal multiple access (NOMA) users. The source varies its power to have a low interference in primary user. RIS with N = 128, 64, 32, 16, 8 reflectors offers 44, 38, 32, 26, 20 dB performance enhancement. Our simulations are valid for Rayleigh channels. RIS using wind and power variation was not yet investigated in literature and is very important for 6G communications. The results are valid for any rotor of area A and any position of RIS, source and destination.

Keywords: wind energy harvesting; reconfigurable intelligent surfaces; RIS; power variation; throughput optimisation; Rayleigh channels.
