Special Issue Information

Dear Colleagues,

The booming deployment of multimedia services, especially high-quality on-demand services, has created fundamental changes in network architecture, from abstraction separation to the service management aspects. Industrial development and academic research are promoting 5G as the next generation of networks which can support vertical applications with different service requirements. To achieve this vision, the 5G physical network should be portioned from different independent logical connections that are composed of different characteristics and requirements. With the advantages of bandwidth, spectrum congestion, coexistence with lighting systems, and radiation exposure, visible light communication (VLC) has emerged as a complementary technology and a valued contributor to both the present communication networks and the next generation of radio frequency wireless communication. This technology is a candidate for 5G development by enormous demand, supporting different 5G requirements and benchmarks. Following the development of VLC, optical camera communication (OCC) or visible light sensor (VLS) is classified by the separation of the receiver technique, image sensor, or photodiode. The development and performance of both visible light communications and optical camera communications are evaluated based on the application scenarios and topologies. This Special Issue is expected to provide the interdisciplinary proposals which enhance visible light communication and optical camera communication development, on the side of modulations, applications, performance evaluation, and related issues.

Underground Mining (UM) is a hostile industry that generally requires a wireless communication system as a cross-cutting axis for its optimal operation. Therefore, in the last five years, it has been shown that, in addition to radio-frequency-based communication links, wireless optical communications, such as Visible Light Communication (VLC), can be applied to UM environments. The application of VLC systems in underground mines, known as UM-VLC, must take into account the unique physical features of underground mines. Among the physical phenomena found in underground mines, the most important ones are the positioning of optical transmitters and receivers, irregular walls, shadowing, and a typical phenomenon found in tunnels known as scattering, which is caused by the atmosphere and dust particles. Consequently, it is necessary to use proper dust particle distribution models consistent with these scenarios to describe the scattering phenomenon in a coherent way in order to design realistic UM-VLC systems with better performance. Therefore, in this article, we present an in-depth study of the interaction of optical links with dust particles suspended in the UM environment and the atmosphere. In addition, we analytically derived a hemispherical 3D dust particle distribution model, along with its main statistical parameters. This analysis allows to develop a more realistic scattering channel component and presents an enhanced UM-VLC channel model. The performance of the proposed UM-VLC system is evaluated using computational numerical simulations following the IEEE 802.1.5.7 standard in terms of Channel Impulse Response (CIR), received power, Signal-to-Noise-Ratio (SNR), Root Mean Square (RMS) delay spread, and Bit Error Rate (BER). The results demonstrate that the hemispherical dust particle distribution model is more accurate and realistic in terms of the metrics evaluated compared to other models found in the literature. Furthermore, the performance of the UM-VLC system is negatively affected when the number of dust particles suspended in the environment increases. Full article
