Maximizing Connectivity of IoT Devices in Smart Street Using 6G Outdoor VLC System

Abstract

Visible Light Communication (VLC) system has emerged as a promising technology for Internet of Things (IoT) connectivity in outdoor environments. It benefits from the existing lighting infrastructure for dual-purpose illumination and communication. This paper proposes a system model for maximizing connectivity of IoT devices in outdoor VLC networks. The paper presents a system model for outdoor VLC-IoT networks incorporating street lighting infrastructure. Channel propagation model in outdoor environments has been investigated. Also, an effective method for improving IoT connectivity devices has been identified. By incorporating advanced modulation schemes, the developed framework enhances both network reliability and transmission quality. Simulation results significant gains in IoT device connectivity with improvements reaching 30%, while the bit error rate (BER) remains below 1 0−9. In addition, the system achieves a higher signal-to-interference-plus-noise ratio (SINR) that contributes to more stable communication.
