Analyzing the Performance Issues in Lifi Technology and Proposed a Solution to Improve its Performance

Abstract

Light Fidelity (LiFi) is a wireless technology that transmits high-speed data using visible light communication (VLC) in the network systems. Light Fidelity technologies are becoming well-liked everyday due to their important role in different applications such as Hospitals, Smart Lighting, Underwater Communication and Harmful Environments etc. The Light Fidelity (LiFi) technologies are in front of different kinds of performance issues in the terms of Signal – to – Noise Ratio (SNR) and Bit – Error Rate (BER). We have done a near examination on different performance issues in Li Fi technology and finally proposed a solution to improve its performance. It was done in experimental approach to the proposed VLC model acknowledges physical layer models portraying the noticeable range mapped to a variety of optical modulation schemes. . We also considered device mobility and direction which exclusively impact an optical receiver. We are also described the adopted physical models, the structure of the NS3 model implementation, and express performance assessment for an Radio Frequency (WiFi) and LiFi (VLC) situation. In this case, when we understand and known to analyze of the VLC (LiFi) downlink and the Radio Frequency (WiFi) uplink are paired using the combination of our NS3 VLC component and accessible NS3 in Radio Frequency modules. When we use the network simulator showed that how this situation can be concentrated regarding the Light Fidelity network in the VLC of Signal – to Noise – Ratio[SNR] and Bit – Error – Rate[BER] boundaries, and in the subsequent of the Network Performance measured.
