“…These communication systems named vehicle to vehicle (V2V) and vehicle to infrastructure (V2I) communications systems . The vehicular communication offers several applications such as violation of a traffic signal, collision warning, emergency brakes light, lane changing, and curve speed warning . For all such applications, a reliable communication system is required that provides exceptionally low latency.…”

Summary With the development of new generation lighting sources, visible light communication (VLC) system has become a complementary solution to traditional radio frequency wireless system. However, the error performance of VLC system is degraded because of multipath effects and interference from other lighting sources that, in turn, reduce the communication range. This work targets the issue of performance degradation of VLC systems in terms of communication range and demonstrates a VLC system design that utilizes forward error correction (FEC) codes as the main tool to fix this issue. Furthermore, the work also covers practical implementation of the proposed VLC system using UART modules programmed in MATLAB. The hardware results demonstrate that the communication range of the proposed VLC system is enhanced up to 0.5 m. Over and above, it is also shown through simulations that the coding gain of the proposed design is more when compared with existing VLC system(s).

“…28 Several applications require high-speed secure data communication for large area network such as vehicular ad hoc networks for detection and prevention of collision and accidents. With the development of open-source platforms like NS3 and NS2, these VLC systems can be modelled for real-time scenarios, incorporating all the real-time effects and obtaining the desired performance parameters for accurate deployment.…”

Visible light communication (VLC) is the branch of optical wireless communi-cations that uses light-emitting diodes for the dual purpose of illumination and very-high-speed data communication. The main motivation behind the current work is finding alternatives to the saturated radio frequency spectrum, radio frequency security issue, and vulnerability to interferences. The current work is aimed at developing a module for the physical layer of a VLC-based ad hoc network in network simulation 3. The VLC physical layer module is developed by using the optical signal modules available in the network simulator.The work also includes modelling of VLC-based transmitter, wireless optical channel, and the optical receiver. Furthermore, the implementation and evaluation of the VLC-based physical layer is carried out over a typical ad hoc network under different performance metrics. The designed ad hoc network is also tested under Wi-Fi module followed by its comparison with corresponding ad hoc network under VLC module. The comparison is based on bit error rate curves, system throughput, and gain in received signal-to-noise ratio mainly.Finally, the suitability of different modulation schemes is also investigated in the current work for both Wi-Fi-and VLC-based ad hoc networks. KEYWORDS ad hoc networks, bit error rate (BER), Li-Fi, modulation SCHEMES, network simulator, NS3, OOK, PAM, PHY layer, throughput, visible light communication (VLC), VPPM, 5G mobile communication | INTRODUCTIONIn the past decade, there has been a drastic increase in the demand for high-speed data communication services (cellular networks, smart TVs, cloud-based computing, high-definition video calling, and live streaming). The existing radio frequency (RF) wireless technologies have been the forefront of telecommunication, revolutionizing the voice and data communication. 1 However, because of saturation of RF spectrum, security issues, vulnerability to interferences, and hazards of RF, low-cost and reliable technologies are required to provide efficient data communication. The discovery and growing use of light-emitting diodes (LEDs) have boosted the research in visible light communication (VLC) technology. 2 Visible light communication is becoming an emerging green technology aimed to providing high data rates for short-range communication and easy deployment in hospitals, planes, and areas where traditional RF systems are less preferred. 3 The VLC salient features include license and interference-free spectrum (430THz-790THz), extremely large bandwidth, inherent security, compatibility with existing technologies, and high efficiency for positioning purposes due to its line-of-sight (LoS) feature. 4

“…Topologi MAC Layer Berdasarkan IEEE 802.12.7 [19] Topologi MAC layer ditampilkan pada Gambar 3 yang terbagi menjadi tiga link, ialah: 1) peer-to-peer, dimana pada topologi ini terdiri dari satu devais sebagai koordinator atau master dan satu sebagai client dimana keduanya dapat berkomunikasi secara dua arah yakni downlink (dari koordinator ke client) dan uplink (dari client ke koordinator). Impelementasinya dapat dilakukan secara half-duplex yakni bergantian antara downlink dan uplink (prinsip ini seperti HT) maupun full-duplex, yakni berkomunikasi secara bersamaan (prinsip ini seperti telefon genggam modern).…”

Abstrak -Penerapan visible light communication (VLC) berlandaskan pada pedoman IEEE 802.15.17 yang mana aturan tersebut baru dirancang dalam waktu 5 tahun belakangan ini (sejak tahun 2009), didalamnya meliputi standar layer fisik (physical layer) dan layer MAC (medium access control). Sebagaimana teknologi komunikasi pada umumnya, VLC juga menyediakan akses security yang dibahas pada bagian layer MAC. Namun pada praktiknya masih belum begitu masif dilakukan oleh para peneliti. Hal ini sangat wajar karena mengingat VLC merupakan teknologi yang sedang dalam tahap pengembangan, yang menjadikan penelitian VLC umumnya berfokus pada 'bagaimana meningkatkan speed dari keterbatasan komponen-komponen pembangun (IC, photodiode, LED, transistor) yang tersedia saat ini. Tantangan teknologi VLC selain target peningkatan kecepatan bit-rate, mobility communication, mengurangi interference noise, menyediakan layanan multi-acces juga salah satunya adalah isu security. Makalah ini merupakan studi literature (review paper) yang didapatkan dari dokumendokumen hasil peneltian baik di jurnal dan conference terkait dengan praktik-praktik security VLC yang pernah dilakukan dengan skema indoor maupun outdoor. Kata kunci -VLC, Security, Komunikasi dan Informasi, ReviewAbstract -Implementing VLC system is based on IEEE 802.15.17 standard where this guideline was designed within the past 5 years ago (since 2009), this guideline covers standard of physical layer (PHY) and medium access control layer (MAC). As communication technology in general, VLC provide security acces which discuss in MAC layer part. However in real practice, we found that they haven't been massively conducted by researchers in the world. The reality is very reasonable due to this technology is under development, it can make VLC studies commonly are focus on "how to increase the speed of VLC with limitations components which are available at this time (such as ICs, photodiodes, LEDs, transistors, etc.)". VLC technology challenges, not only 1) to increase the speed of bit-rate, 2) serve mobility communication, 3) reduce noise interference, 4) providing multi-service acces, but also how to implement security issues in VLC. This paper is a study of literature (review paper) which are obtained from the scientific documents from journals and conferences related to security practices VLC both for indoor and outdoor schemes. Haas di tahun 2011 tentang Light Fidelity (Li-Fi) pada forum TEDx menujukkan bahwa terobosan teknologi ini dapat dijadikan alternatif komunikasi masa depan yang mana memiliki kelebihan dibandingkan teknologi komunikasi wireless lain seperti infra-red, fiber-optic dan radio frequency, yakni bebas regulasi, cakupan bandwidth yang lebih besar, aman untuk kesehatan dan masih banyak yang lainnya. Sifat dari visible light adalah tidak dapat menembus objek padat seperti
