Analysis of Water-Filling Random Resource Allocation (W-FRRA) for Energy Saving in Light Fidelity (LiFi)

摘要

Abstract一In this research, we proposed the resource management based on random mobility for energy savings, called Water-Filling Random Resource Allocation (VV-FRRA). To prove our intended, we simulated massive users with different channel conditions in (he closed room. We consider that Access Point (AP) has a controller to collect channel state information (CSI) and give several users more power to poor channels, dynamically. We also evaluate our proposed with different maximum and 1111111mum transmitted power. From an extensive simulation study, our results show that best energy savings and performance i$ obtained using maximum and minimum 3 and 0.8 Watt transmitted power, respectively. For performance, average data rates are achieved around 1^ Mbps and energy saving up to 46%. A random user's location and condition affect the Fairness Index (FI) value to 53%. Using coded domain Non-Orthogonal Multiple Access (NOMA) instead of the power domain, wc proved that energy saving in different transmitted power does not affect the performance significantly. The performance shows that the total user to serve is 40 for a single AR At the end of the research, we found that using the W-FRRA algorithm a$ energy savings can extend the Light Emitting Diode (LED).
