Visible light communication (VLC) is a new paradigm that could revolutionise the future of wireless communication. In VLC, information is transmitted through modulating the visible light spectrum (400–700 nm) that is used for illumination. Analytical and experimental work has shown the potential of VLC to provide high-speed data communication with the added advantage of improved energy efficiency and communication security/privacy. VLC is still in the early phase of research. There are fewer review articles published on this topic mostly addressing the physical layer research. Unlike other reviews, this article gives a system prespective of VLC along with the survey on existing literature and potential challenges toward the implementation and integration of VLC.

“…VLC is extensively researched nowadays due to ever-growing number of communication devices and the increasing popularity of advanced services leading to congestion of the radio frequency (RF) spectrum. The concept of building smart cities by exploiting the ubiquity of lights to ease the RF spectrum shortage, as presented in [12]. Apart from quality of service (QoS) in VLC, the illumination conditions are equally important in order to build intelligent ubiquitous cities.…”

The concept of interactive visible light communications (iVLC) is introduced and discussed in this paper. iVLC exploits a matrix of solid-state light luminaries in multiple ways, namely providing lighting and wireless communications as well as supporting visual signaling and interaction. Every individual element of the light matrix can be exploited in multiple domains, i.e., space, time, color, intensity and data. As a result, the lighting infrastructure works a flexible platform that can be exploited in wide range of applications and use cases. The paper discusses attractive applications of iVLC, particularly in the school of the future, health-care and office spaces. Multiple classroom tasks can be supported by iVLC, including orchestration of activities, feedback between students and teachers, dynamic grouping, etc.

The clustering method in the vehicular ad-hoc network provides an opportunity for a cluster head to improve the network connections, but it still remains a problem in the border cluster. The vehicles, in view of their position in the slices of two clusters, receive a weak signal from the cluster head. The intersection area causes a throughput decrease for cluster members. To provide the network connection in the border cluster, we, in turn, proposed an adaptive border node clustering by utilizing the combination of K-Medoids algorithm, modified Genetic Algorithm and modified Tabu Search. We ameliorated the recent model in Enhanced Model of Weighted K-Medoids Clustering Algorithm by adding the fusion process to the best gene pieces into one individual temporary. The effects of this fusion were on the production of a temporary cluster that can make the main cluster environment more stable. This temporary cluster was adapted to the position of the two closest main cluster heads. Our model was found able to increase throughput and to keep the stability of cluster members at any velocities. The increase in throughput represents an improvement parameter in the network quality of service (QoS). We achieved the overall throughput at 93.97% (throughput vs cluster member) compared with the previous methods and the cluster member stable at around 25 vehicles (cluster member vs transmission range) in varied conditions.
