“…Therefore, the UVLC techniques are the potential wireless candidate for communication and transmitting energy media within the networks. Due to this, simultaneously, lightwave information and power transfer (SLIPT) has been proposed as a potential wireless candidate for communication and power transmission through optical link connectivity [243]. Compared with simultaneous wireless information and power transmission (SWIPT), SLIPT performs better in specific channel condition requirements.…”

In recent years, underwater visible light communication (UVLC) has become a potential wireless candidate for signal transmission in highly critical, unknown, and acrimonious water mediums such as oceans. Unfortunately, the oceans are the least explored reservoirs in oceano-geographical history. However, natural disasters have aroused significant interest in observation and monitoring oceanic environments for the last couple of decades. Therefore, UVLC has drawn attention as a reliable digital carrier and claims a futuristic optical media in the wireless communication domain. Counterparts of traditional communications, the green, clean and safe UVLC supports high capacity of data-rate and bandwidth with minimal delay. Nevertheless, over long ranges, the deployment of UVLC is challenging rather than terrestrial basis communication. Additionally, VLC systems suffer from signal attenuation and strong turbulence channel conditions. Due to the fact that, this study provides an exhaustive and comprehensive survey of recent advancements in UVLC implementations to cope with the optical signal propagation issues. In this regard, a wide detail summary and future perspectives of underwater optical signaling towards 5G networks along with the current project schemes, channel impairments, various optical signal modulation techniques, underwater sensor network architectures with energy harvesting approaches, hybrid communication possibilities, and the Internet of underwater things (IoUTs) are concluded in this research.

In this article, the secrecy performance of a hybrid radio frequency (RF)/visible light communication (VLC) system is studied. In this hybrid system, the source node (i.e., Alice) transmits information to the relay node via the outdoor RF link. Nakagami-m fading and path loss are considered for the RF link. The relay node includes an outdoor component and an indoor component, which are connected by using a wired medium. The outdoor component receives and recovers information by using the decode-and-forward (DF) relaying scheme and then transmits it to the indoor component. The indoor component then converts the received electrical signal into an optical signal by using a light-emitting diode. A legitimate receiver (i.e., Bob) deployed on the floor receives the optical signal. An eavesdropper (i.e., Eve) deployed in the RF or VLC link wiretaps the confidential information. In this study, we use the secrecy outage probability (SOP) and the probability of strictly positive secrecy capacity (SPSC) to evaluate the system performance. We then obtain the closed-form expression for a lower bound on the SOP and an exact closed-form expression for the probability of SPSC when the RF and VLC links are wiretapped, respectively. Numerical results are presented to validate the accuracy of our derivations. We further discuss the effects of the noise standard deviation, the equivalent threshold of the signal-to-noise ratio, and the floor radius on the system secrecy performance when the VLC link is eavesdropped upon. For the case when the RF link is eavesdropped upon, the impacts of the distance between Alice and the relay, the path loss exponent, the fading factor, and the distance between Alice and Eve on secrecy performance are also provided.

Visible light communication (VLC) is considered to be a great replacement or complement to existing radio frequency networks to provide the future fifthgeneration (5G) wireless technology with higher data rates for indoor connectivity, which alleviates the traffic demand. Therefore, many issues emerged regarding the security in 5G networks as human safety is at risk. This work presents a comprehensive study on the physical-layer security (PLS) and solutions in 5G networks, specifically, the security of VLC technology as one of the core PLS solutions for 5G future wireless networks. Furthermore, VLC threats and PLS solutions are extensively investigated. Based on our study, we propose a new indoor VLC secure model to enhance the secrecy performance in VLC networks using a combination of multiple PLS techniques to achieve this aim as beamforming, secure communication zones, and friendly jamming. The simulation results with respect to the received optical power and signal-tonoise ratio (SNR) prove that the proposed indoor VLC model can improve the secrecy performance. As the user's SNR exceeded 100 dB and optical received power reached 15 mW, the malicious user's SNR barely reached 30 dB with a 4-μW received power outside the target zone increasing his interference level.Finally, future research directions in VLC security are outlined to encourage future research.
