“…The simulation results show that using multiple technologies can improve the reliability of communication for platooning applications. In 2016, the authors in [12] proposed an optical CDMA based on the quality of service (QoS) required by each node in the network. The optical codewords implemented are not detailed in the paper.…”

One of the most critical challenges in vehicle-to-vehicle (V2V) visible light communications (VLCs) is the access capability of multi-users over the same channel. VLC links are known to be line of sight (LOS) and highly directional compared to the commonly used radio-frequency (RF) technologies, but multi-user interference can still be problematic. Consequently, it is necessary to develop a medium access control (MAC) protocol for VLC. In the present work, we propose a novel optical code division multiple access (OCDMA) protocol. The fundamentals of the VLC channel are presented, and the interference problem is discussed in more detail. We also explain the CDMA MAC protocol and its adaptation from optical fiber communications. The simulations with our OCDMA protocol based on pseudo-noise (PN) sequence codes are presented, and the results are compared with those obtained using a solution based on VLC and optical orthogonal codes (OOCs) from the OCDMA gold standard. Finally, the results show that PN sequence OCDMA can provide sufficiently high performance and is particularly attractive because there are no synchronization requirements between nodes in real V2V scenarios.

“…However, the extended distance of a single-hop relay is limited. To overcome this, M. Garai et al proposed a tree-based architecture vehicular VLC networks (V2LCnet), which provided a rapid connection between several destination vehicles (DVs) and the source vehicle (SV) using multi-hop communications, thus notably increasing the overall coverage area [10]. However, in the proposed scenario, the SV was highly connected, thus resulting in increased communication latency and therefore network congestion.…”

The use of visible light communications (VLC) in intelligent transportation systems is becoming highly popular. In this paper, we present a predictionbased channel gain model and propose a multi-hop relay-based routing algorithm for vehicular VLC communication networks. Using the surrogate modeling lab platform SUMO and Matlab we show that, a stationary velocity of vehicles is better suited to form a good prediction, while the proposed routing algorithm offers improved signal-to-noise ratio.
