MAC Layer Design for Network-Enabled Visible Light Communication Systems Compliant with IEEE 802.15.7

Abstract

The design and implementation of medium access control (MAC) layer for network-enabled visible light communication (VLC) system is presented in this paper. The point-to-point link was chosen because of its simple in configuration as well as implementation. Whereas the FPGA Zybo Zynq-7000 is employed for prototyping the hardware of VLC system because of it serve a Linux operating system (OS), i.e. Xillinux. Our MAC layer has been realized in Python programming and running above the Zynq-7000 processor. The designed MAC Layer is adapted from IEEE 802.15.7 standard, specifically for delivering and receiving the MAC frames from the coordinator to the device or vice versa, wrapping the IP packets and unwrapping the MAC Frames with MAC headers and trailers, and performing the error detection in which the cyclic redundant check 16 (CRC-16) was selected. According to the functionality test, our proposed VLC system can perform to send the multimedia contents (video and image) as well as data packet for internet accessing purpose like a wireless fidelity (Wi-Fi) connectivity. Thus, it can be concluded that the implemented MAC layer has met the functionality specifications referred to the IEEE 802.15.7 standard. We also provide the Pseudo-code of designed MAC layer and its Python script (source-code) implementation that can be found in the Appendix section.

Integration of LiFi, BPL, and Fiber Optic Technologies in Smart Grid Backbone Networks: A Proposal for Exploiting the LiFi LED Street Lighting Networks of Power Utilities and Smart Cities

“…Historically, the earliest known VLC technology application comes from A. G. Bell, who demonstrated in 1880 the photophone that transmitted voice data over 200 m using sunlight beams [25,26]. Recently, H. Haas has proposed a modern concept of the LiFi system while IEEE 802.15.7 has standardized its PHY and MAC layers [15,[27][28][29]. Being able to deliver high data rates for various broadband services via IEEE 802.15.7, LiFi systems can cope with optical transmission mobility, compatibility with artificial lighting and the interference which may be generated by ambient lighting.…”

Rapid Development of System-on-Chip (SoC) for Network-Enabled Visible Light Communications

“…The functionality test of Xillinux OS ensures that it is ready to be employed in developing the required software include booting up as visualized in our previous research [13], loading the standard user interface as depicted in [9], and running the Python script as shown in Fig. 12.…”

“…In previous work, we have developed MAC Layer software that is written in Python script [9], to execute this programs, we need an OS. The FPGA Zybo board has ARM-based processor that capable to run the Linux OS.…”
