The Advent of 5G Wireless Networks: Enhancing Spectrum Efficiency and Quality of Service Provisioning

Abstract

The advent of 5G wireless networks is set to revolutionize communication systems by significantly improving spectrum efficiency and Quality of Service (QoS) provisioning. Full-duplex device-to-device (FD-D2D) communications, mobile fog computing, and radio network aggregation are among the key innovations enhancing these aspects. This paper explores the contributions of FD-D2D communications, advanced power allocation frameworks, and mobile fog computing to 5G networks. Additionally, it discusses the application of the Lyapunov drift-plus-penalty theorem for throughput maximization and queuing stabilization, highlighting the role of these technologies in the evolution of 5G networks.
