Network Architectures and Protocols for Efficient Exploitation of Spectrum Resources in 5G

Abstract

AbstractWith the emergence of 5G technology with its enhanced architecture, there are unprecedented possibilities in terms of Quality of Service (QoS), data rate, latency, and capacity. This chapter throws light on different aspects of 5G technology and associated technological innovations. It has support for user diversity, devise diversity, and other dimensions. It focuses on the architecture of 5G technology, its underlying mechanisms, support for Device-to-Device (D2D) communication, Multiple-Input Multiple-Output (MIMO) enhancements, advanced interference management, enhanced utility of ultra-dense networks, spectrum sharing, and cloud technologies associated with 5G networks. It also proposes a methodology with spectrum broker with underlying components with delay-aware and energy-efficient approach to leverage 5G base stations leading to the reduction of energy consumption. The concept of queueing delays is considered while proposing the scheme for delay-sensitive communications with energy efficiency. The spectrum broker has mechanisms to achieve this. Simulation study with the proposed scheme shows the energy efficiency of the proposed scheme when compared with the state of the art. This chapter not only provides the required know-how on different technologies but also provides the simulation study that may trigger further investigation into the resource management in 5G networks.
