Li-Fi Technology: Architectures and Data Transmission Mechanisms

This paper introduces a set of novel Li-Fi architectures and communication techniques based on visible light communication through LEDs. The proposed solutions aim to improve accuracy, adaptability, and data security in optical wireless systems, while ensuring smooth integration with existing network infrastructure and environmental conditions. The mechanisms include energy-saving algorithms, support for mobile users, and advanced cryptographic approaches to reduce traditional limitations such as line-of-sight constraints and signal interference. Analytical evaluations confirm the scalability and effectiveness of the designs, presenting a foundation for future implementations of Li-Fi in energy-conscious digital environments.
