Notice
On May 12th a massive fire broke out at Marywilska 44, one of the Warsaw's largest shopping centers. This unexpected incident caused power outages in the surrounding area including the ICM data center where OpenAIRE services run. Efforts are underway to restore the power and to get services back online. Some functionalities will not work properly until then.
We apologize for any inconvenience this may have caused.

Energy and Spectral Efficiency of Multi-Tier LiFi Networks

Abstract

In this paper, multi-tier LiFi networks are studied in terms of energy efficiency (EE) and spectral efficiency (SE), which are crucial metrics for LiFi system design. We derived a closed-form expression of the user association probability for different tiers using stochastic geometry based Poisson Voronoi Tessellation (PVT) LiFi network. The performance metrics of the network, EE and SE, are analyzed in terms of different parameters such as transmit power and Lambertian index. Performance evaluations and numerical results show that multi-tier LiFi networks have an optimum transmit power in which EE is maximized. Besides, increasing the transmit power does not increase SE after passing a threshold point. The resulting trade-off between EE and SE is presented.
