Abstract: In this paper, we optimise the instantaneous and average throughput of wireless communications when the source harvests power from wind. We select the value of packet length to optimise the instantaneous or average throughput. Instantaneous throughput optimisation offers up to 5 dB gain versus average throughput optimisation. Average throughput optimisation offers a larger throughput than any packet length. We also study the effects of average wind speed and the results are obtained for Rayleigh channels. We derive the SNR statistics when the source harvests power from wind. Our derivations are valid for any position of nodes and any average wind speed. Average throughput optimisation offers a larger throughput than any packet length as suggested in the literature. We obtained up to 1.5 dB gain using average throughput optimisation when compared to packet length N = 200, 500. Instantaneous throughput optimisation allows up to 5 dB gain versus average throughput optimisation.

Keywords: wind energy harvesting; average and instantaneous throughput optimisation; Rayleigh channels; Nakagami channels; optimal packet length.
