Sequential Load Balancing for Link Aggregation Enabled Heterogeneous LiFi WiFi Network

IEEE Open Journal of Vehicular Technology, 2022
Light fidelity (LiFi) is one of the promising communication technology for 6G internet of everything (IoE), however, it requires a line-of-sight (LoS) link; in contrast, WiFi can support moderate data rates even in the absence of LoS.

Smart Handover for Hybrid LiFi and WiFi Networks [PDF]

IEEE Transactions on Wireless Communications, 2020
This work investigates handover in hybrid light fidelity (LiFi) and wireless fidelity (WiFi) networks (HLWNets). In such a network, the handover process becomes challenging due to two main factors: i) the relatively short coverage range of a single access point (AP), and ii) the largely overlapping coverage areas of different networks.

Testbed for a LiFi system integrated in streetlights [PDF]

2015 European Conference on Networks and Communications (EuCNC), 2015
In this paper, a functional LiFi real-time testbed implemented on FPGAs is presented. The setup evaluates the performance of our design in a downlink scenario where the transmitter is embedded on the streetlights and a mobile phone’s camera is used as receiver, therefore achieving the goal of lighting and communicating simultaneously.

Solution‐Processed Tunable Spectral Response Photodetectors Enabled by Acidochromic Polymers

Advanced Electronic Materials, Volume 12, Issue 11, 8 June 2026.
Tunable spectral response photodetectors have been fabricated by using acidochromic polymers in photodiode and phototransistor geometries with organic/inorganic semiconductor heterojunctions. The spectral response of the photodetector has been tuned from the visible to the NIR region by using vapor‐phase trifluoroacetic acid (TFA) in a reversible way ...
