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.

“…All contention-based transactions must be completed before the CFP begins. Therefore, the CFP always appears at the end of the superframe immediately following the contention access period [15]. The superframe is bounded by beacons sent by the coordinator.…”

“…A comprehensive PHY performance evaluation of the IEEE 802.15.7 is presented in [9], and there are several studies focusing on modulation [10,11] and resource allocation [12]. IEEE 802.15.7 MAC layer performance was not explored in depth except some sporadic works [13][14][15][16][17]. In [13], the performance of beacon-enabled mode of 802.15.7 in terms of throughput and delay is studied through computer simulations.…”

“…The focus in [14] and [16] is on the modification of MAC layer to introduce priority mechanism and cooperative communication rather than a thorough performance evaluation of the original standard. In [15], throughput and packet discard probability for network performance metrics including throughput, delay, power consumption, collision probability, transmission probability, access probability and packet discard probability. The derived expressions are further validated via simulations.…”

VLC uses the illumination infrastructure to meet broadband needs of bandwidth-hungry devices. Its high data rate, immunity to electromagnetic interference, ability to operate in an unlicensed band and high reuse factor position VLC as a strong alternative to existing communication technologies. The physical and medium access control (MAC) layers of VLC have been standardised in IEEE 802.15.7. Yet, theoretical performance bounds of the MAC layer have not been explored in detail so far. In this paper, we derive Markov-based performance bounds for the MAC layer of IEEE 802.15.7. We provide a thorough study of throughput, delay, power consumption, collision probability, transmission probability, access probability and packet discard probability using analytical analysis and simulations.Istanbul Development Agenc

VLC has recently emerged as a promising alternative/complementary technology to conventional radio-frequency wireless access and has been standardized in IEEE 802.15.7. In this paper, we model the multiple access mechanism of IEEE 802.15.7 standard with a Markov chain and present simulation results for the network performance metrics including throughput, delay, and packet delivery.Qatar National Research Fun
