Analyzing Optical TDMA to Mitigate Interference in Downlink LiFi Optical Attocell Networks

Coverage Analysis of a Thinned LiFi Optical Attocell Network

This work analyzes coverage in the downlink of a thinned LiFi attocell network of deterministically arranged LEDs. The network is thinned by a Bernoulli probability p over all the LEDs to decide whether each one of them acts as a LiFi source or not. Then we use the series approximation approach used in [1] to obtain closed form expressions for the probability of coverage in such thinned LiFi attocell networks and validate them using numerical simulations.

Multi-Hop Wireless Optical Backhauling for LiFi Attocell Networks: Bandwidth Scheduling and Power Control

The backhaul of hundreds of light fidelity (LiFi) base stations (BSs) constitutes a major challenge. Indoor wireless optical backhauling is a novel approach whereby the interconnections between adjacent LiFi BSs are provided by way of directed line-of-sight (LOS) wireless infrared (IR) links. Building on the aforesaid approach, this paper presents the top-down design of a multi-hop wireless backhaul configuration for multi-tier optical attocell networks by proposing the novel idea of super cells. Such cells incorporate multiple clusters of attocells that are connected to the core network via a…
