Instantaneous and average throughput optimization using reconfigurable intelligent surfaces with solar energy harvesting

In this paper, we optimize the instantaneous and average throughput when wireless communications uses Reconfigurable Intelligent Surfaces (RIS) and the source harvests power from sun using a Photo-Voltaic (PV) system. Instantaneous throughput optimization offers up to 6 dB gain versus average throughput optimization. Average throughput optimization offers a higher throughput than any packet length. Performance gain is up to 1 dB gain using average throughout optimization versus other values of packet length.
