Paradigms of modeling and improving the reliability of data transmission in VLC technologies

Purpose. Development and improvement of data transmission process modeling methods in VLC systems to enhance their reliability, noise immunity, and ensure stable operation under external and internal uncertainties. Methodology. The tasks set are realized on the basis of a comprehensive analysis of scientific literature and patent sources, as well as on analytical, experimental and modeling studies. Mathematical and simulation methods are applied to assess the impact of uncertainties and disturbances in VLC systems. In addition, correlation approaches for quantitative assessment of channel stability and transmission error risk prediction algorithms are applied, which allows identifying key reliability parameters under external and internal influences. Findings. The paradigms of modeling of data transmission processes in VLC systems taking into account uncertainty and interference factors are developed. It is shown that high reliability of communication is achieved by integrating mathematical and simulation models for assessment of the risks of false and undetected defects. The key factors of stability are metrological support, control accuracy and reduction of design risks. The proposed models allow improving the systemic quality of design and operation of VLC-systems ensuring their performance under external and internal influences. The developed approaches are applicable to optimization of the architecture and technological solutions in reliable wireless optical networks. Originality. A methodology has been developed for the quantitative assessment of risks of data transmission parameter control under conditions of uncertainty of normative values. A new paradigm for the robust design of VLC systems has been introduced, which takes into account the statistical characteristics of measurement errors and the influence of agent uncertainties. Algorithms for machine modeling of the probabilities of false and undetected defects under conditions of uncertainty in control standards have been proposed. Practical value. Methods of quantitative assessment of control risks and improvement of data transmission reliability in VLC systems have been developed. Mathematical and simulation models allow one at the design stage to take into account more accurately the influence of metrological and operational factors on the quality of operation of optical data transmission channels. The algorithms are applicable for optimization of the element base, operation modes and channel condition monitoring. The results are relevant for reliable wireless networks in conditions of increased requirements to information security and for critical facilities.
