Toward 5G cloud radio access network: An energy and latency perspective

Abstract

Future generation networks will entirely deploy virtualization paradigms to enhance performance and capabilities of current cellular networks. In order to achieve the vision of fifth‐generation networks, software‐defined networking and network function virtualization will be applied not only at the core network but also at the radio access network. That will help to achieve significant reduction in power consumption while increasing energy efficiency, flexibility, and scalability. This article proposes a general mathematical model that can correctly and accurately describe spatial/topological characteristics, power consumption, and latency of Cloud radio access network in future generation networks. Thanks to the development of this novel model based on stochastic geometry, tessellation theory, and random multilayer hypergraphs, we can numerically estimate the overall energy efficiency (in bit per Joule) of Cloud radio access network in 5G (considering either edge or cloud computing), and we can compare that to energy efficiency of legacy radio access network of current 4G cellular networks. Moreover, the analysis includes a preliminary discussion about latency; that shows edge computing to be the best paradigm for 5G radio access network, which can concurrently satisfy energy efficiency and latency requirements.

“…The vigorous development of IoT technology has laid a solid foundation for continued growth in the 5G era [1,2]. Therefore, networking, artificial intelligence, virtual reality (VR), and augmented reality (AR) technology can be used to provide relevant local 5G-centered services in health care, education, and other fields [3,4].…”

Cost assessment of elasticity for a 5G broadband network

“…7 Several studies have investigated different aspects of cloud radio access networks. [8][9][10] While the advantages and employment of resource elasticity in 5G wireless networks have been studied in the literature, 7,11,12 no studies have been published so far regarding the cost implications in terms of the impact on the total cost of ownership (TCO) of elasticity in large-scale 5G networks. A few cost analyses regarding 5G have been published over the last few years, but they have not covered all cost aspects of 5G.…”
