“…Precision = TP FP + TP (5) Recall = TP FN + TP (6) As detailed in Table 2, the training achieved satisfactory results with the YOLOv8 trained model achieving 0.98 mAP at 0.50 IoU. Compared to the previous YOLO, the accuracy did not reduce heavily and only fluctuated around 0.97 and 0.98 of mAP at 0.50 IoU.…”

“…Furthermore, the emergence of wireless communication technology may contribute to the depletion of RF waves during the formation process [ 4 ]. Conversely, the past decade has witnessed a surge in the usage of mobile devices such as smartphones, tablets, and sensors, intensifying the demand for a higher bandwidth spectrum [ 5 ]. Optical wireless communication (OWC) presents a potential solution to this problem, leveraging the vast and unregulated bandwidth of optical light, spanning 200 THz in the 700–1500 nm range [ 6 ].…”

In recent years, optical camera communication (OCC) has garnered attention as a research focus. OCC uses optical light to transmit data by scattering the light in various directions. Although this can be advantageous with multiple transmitter scenarios, there are situations in which only a single transmitter is permitted to communicate. Therefore, this method is proposed to fulfill the latter requirement using 2D object size to calculate the proximity of the objects through an AI object detection model. This approach enables prioritization among transmitters based on the transmitter proximity to the receiver for communication, facilitating alternating communication with multiple transmitters. The image processing employed when receiving the signals from transmitters enables communication to be performed without the need to modify the camera parameters. During the implementation, the distance between the transmitter and receiver varied between 1.0 and 5.0 m, and the system demonstrated a maximum data rate of 3.945 kbps with a minimum BER of 4.2×10−3. Additionally, the system achieved high accuracy from the refined YOLOv8 detection algorithm, reaching 0.98 mAP at a 0.50 IoU.

“…In recent years, the wireless communication bandwidth traffic has witnessed a dramatically rapid increase which has rendered the traditional radio frequency (RF) spectrum almost overcrowded [1][2][3]. It is worth mentioning that the International Data Corporation's recent report expects 22 billion active Internet of Things (IoT) devices in 2018 to attain 41.6 billion in 2025, producing 79.4 zettabytes of data.…”

“…Additionally, Cisco's 2018-2023 Annual Internet Report claims that more than two-thirds of total traffic is caused by mobile wireless devices. It is expected that from 2027 to 2030, the sixth generation (6G) wireless communication systems, fully supported by artificial intelligence, will become an effective approach to wireless communication [1,4]. Considering this exponentially growing need for more smart wireless devices that accommodate higher capacities with higher security level operating at the lowest possible power consumption, remarkable research and industrial attention has been lately attracted to the transition to the optical spectrum, as demonstrated by the continual emergence of even newer high-capacity services and varying sophisticated applications.…”

In recent years, the tremendous increase in data traffic carried by wireless communication networks has generated the urgent need for establishing more energy-efficient wireless communication systems. Recent advances in semiconductor and light devices have triggered remarkable research interest to the development of these optical wireless communication (OWC) links. Among them, free-space optical (FSO) links and, more recently, ultraviolet links which operate within the (UV-C) spectral band, have been considered as prime candidates to create both high speed and power effective line-of-sight (LOS) and non-light-of-sight (NLOS) free-air communication links, respectively. Moreover, transdermal optical wireless (TOW) links for telemetry with medical implants minimize the expense of power for the implant. In the current review, a background on the energy efficiency challenges in wireless communication is presented. Each of these OWC technologies is mainly discussed in terms of key energy consumption requirements and major limiting factors that affect their power performance. Energy-efficient modulation formats as well as other powerful techniques for performance enhancement such as diversity and relaying are assessed. The survey is concluded with a discussion regarding their future energy consumption requirements and trends.

“…Due to their tiny size, the attocells produce excellent spatial-spectral efficiency (SE) and encourage frequency reuse by preventing adjacent LiFi AP users from inter-cell interference [ 5 ]. In [ 6 ], research on the next-generation optical communication infrastructure—evolving concurrently with the demands of mobile communication systems requiring 5G and beyond—was presented. This research included optical-wireless communication (OWC), free-space optical communication (FSOC), and visible-light communication (VLC).…”

A hybrid network has recently been proposed as a framework for a high-speed wireless communication network. Basically, it integrates light fidelity (LiFi) with radio frequency wireless gigabit alliance (WiGig) networks that operate, simultaneously, in a completely different frequency band. To assign the best access point (AP) and provide enough resources for each user, an effective load-balancing (LB) strategy is needed. However, the traditional LB strategies involve sophisticated iterative computing procedures whenever the user distribution changes. Hence, the first contribution of this work is to offer a more adaptable, two-step, conditional, and most-correlated distribution (CMCD) algorithm. Thus, the low-complexity most-correlated distribution (MCD) LB scheme is applied, and the average data rates for all users are then calculated. If the results achieve the predefined performance threshold (PDT), the decisions will be confirmed; otherwise, the proposed scheme automatically switches to the more accurate, but more complex, consecutive assign WiGig first separate optimization algorithms (CAWFS) algorithm. The suggested algorithm provides a clear performance-complexity trade-off, which could be simply controlled by choosing the suitable performance tolerance factor. The second contribution of this paper is the correlation-weighted majority voting (CWMV) method, which attempts to benefit from as many prior decision votes as possible, instead of relying just on one vote. In the CWMV technique, the weight of each vote is calculated based on the correlation between the history distribution vectors and the new user distribution vector. A significant increase in the system performance is evident from the simulation results.
