“…Both GWO and PSO offer a significant Slow convergence in the later stage [170], [171] Fewer parameters that do not require fine-tuning Low solution accuracy improvement of 58.16% and 55.51% in 3D environments while reducing the computational complexity of the problem. GWO is also applied in [115] combined with the non-sorting genetic algorithm III (NSGA-III), to formulate a multiobjective optimization strategy that maximizes power and spectral efficiency in a VLP system and utilizes an LSTM to predict PD positions, based on the optimal solutions of the HMO process. The proposed method obtains a reduction of 80% in power consumption and 20% in spectrum bandwidth.…”

“…VLC utilizes visible light as the information carrier and is attracting growing attention due to license free available spectrum, high spatial reuse, and high security [1]. VLC and in general optical wireless communications (OWC) have many applications in indoor positioning, intelligent transport systems, and the Internet of Things (IoT) among others [2], [3]. Researchers have utilized commercial LEDs as the optical front end of the transmitter and achieved impressive results.…”

A combination of a blue laser diode (LD) and a warm white light emitting diode (LED) has been used for indoor lighting and visible light communications (VLC). Contrary to LD and phosphor based white lighting communication, no blue LD power is lost due to phosphor conversion. As a result, a longer communication distance has been achieved. The laser beam is diffused in a hat-top profile by an engineered diffuser in such a way that the received signal strength remains flat over a large area, thus improving the coverage area of the communication system. The experiment demonstrates a 1.7 Gbits/s communication speed over a distance of 1.85 m keeping bit error rate (BER) below 2.8 × 10 −3 over a large area. The coverage area has been improved by 238% to 2.27m 2 using the hat-top diffuser from 0.95m 2 for a phosphor diffuser. This is the largest reported coverage area for the achieved VLC speed at 1.85 m distance to the best of the authors' knowledge. A correlated color temperature (CCT) of 2952 and a color rendering index (CRI) of 86 have been achieved and the blue light exposure has been kept under the permitted limit. As the radiation standards for eye safety are more relaxed for the infrared (IR) spectrum compared to the visible spectrum, a near-IR LD has been utilized to achieve higher data rates. A data rate of 2.55 Gbits/s has been achieved using the near-IR LD and the proposed diffuser for the same coverage area and distance.INDEX TERMS Visible light communications, VLC coverage, optical wireless communications, free space optics, hybrid LED-LD, OWC, engineered diffuser.
