| dc.description.abstract | The implementation of the fifth generation (5G) of cellular networks has led to a large increase in mobile traffic, with applications demanding ultra-high trans mission speeds and high quality of experience (QoE), requiring a network infras tructure capable of supporting multiple new services. Femtocell VLC/RF hybrid systems are complementary technologies that enable cooperation between RF and VLCnetworks without interfering with each other. They significantly increase the data rate of the system and achieve better load balancing by distributing the load between the two networks. Femtocell-type VLC/RF hybrid networks are key to the next generations of cellular networks because they can complement the ad vantages of both independent technologies. However, there are still many areas of research and several challenges to overcome for optimal management of hybrid VLC/RF Femtocell networks. In this work, we propose a new way to design and validate management mechanisms for hybrid VLC/RF networks to control access to the medium and network resources. With this research, we expect to obtain ma nagement mechanisms for hybrid Femtocell VLC/RF networks to control access to the medium and network resources, successfully increasing the hybrid system’s performance in terms of network throughput, transmission efficiency, and network effectiveness despite the user’s mobility. These mechanisms can be validated using a discrete event simulator. The design and validation of management mechanisms to optimize access and resource usage in hybrid VLC/RF networks demonstra ted an increase in network performance, reflected in higher throughput, better transmission efficiency and greater system effectiveness. A hybrid indoor Femto cell system was proposed, incorporating a CSMA/CA and IEEE 802.11n-based access protocol, resulting in reduced latency and improved throughput compared to standalone networks. In addition, three network selection algorithms were de veloped that prioritize the connection through VLC and improve the quality of service, with the Analytical Algorithm standing out for its efficiency. Simulations confirmed that the hybrid network optimizes user connection and distributes the load evenly between VLC and RF. | en |
