Sažetak
With the rapid growth of wireless communication, congestion and interference in the RF spectrum have become significant challenges, leading to degraded quality of service (QoS). To address this issue, we propose an intelligent RF-integrated Optical System that dynamically switches user data transmission between RF and Visible Light Communication (VLC) based on real-time spectrum conditions. The core novelty of our approach lies in the application of the Wader Hunt Optimization (WaHO) algorithm, a bio-inspired metaheuristic method, for intelligent spectrum switching in hybrid RF-VLC Network. WaHO is utilized to continuously monitor RF spectrum usage, detecting interference and congestion patterns. When the RF spectrum is deemed unsuitable, the system autonomously redirects communication to the VLC spectrum, ensuring seamless data transmission. The key contributions include congestion aware spectrum switching and energy efficient hybrid communication. The experimental baseline of spectroscopic study investigates the real time interactions of different spectra and its interference when RF and Optical spectra are hybridized in wireless networks. The performance analysis of WaHO based dynamic spectral switching in RF integrated Optical System (RFiOS) proves that the enhanced data throughput is achieved and gives significant adaptability rating to next generation wireless networks.
