Abstract : The light fidelity (Li-Fi) is a wireless optical networking-based technology that can use LEDs for the transmission of data and photodiodes for the reception of data. This research aims to develop a medium access control (MAC) layer for Li-Fi that conforms to IEEE 802.15.7 standard specification for Li-Fi. We focus on visible light (VLC)-based communications among multiple nodes, where our system can support all three topologies such as peer-peer, star, and broadcast as specified in the IEEE specification document. Further, this paper focuses on MAC layer functionalities such as generating network beacons if the device is a coordinator, supporting OWPAN association and disassociation, synchronization with multiple channel resource management, and visibility with dimming support. The target digital signal processing (DSP) unit for the work is chosen as a Zynq-7000 series FPGA. We provide all these functionalities using MATLAB and Simulink-based model, and our implementation has passed through hardware code generation and verification such that the next step of implementation on FPGA can be easily carried out.
