摘要:

雾无线电接入网络(F-RAN)和虚拟化是5G网络的有前途的技术。在F-RAN中,雾和云计算被集成,其中传统的C-RAN功能被分散到无线电接入网络的边缘设备。采用F-RAN来减轻前传的负担并改善端到端(E2 E)延迟。另一方面,虚拟化和网络功能虚拟化(NFV)是旨在将功能从硬件转换为基于软件的功能的IT技术。在移动网络中使用NFV可以带来许多优点,包括高度的可靠性、灵活性和能量效率。本文介绍了一种用于F-RAN的虚拟化框架,以提高5G网络的能效。在该框架中,千兆无源光网络(GPON)被用作所提出的F-RAN架构的骨干网络,其中它经由光纤电缆连接若干演进节点B(eNodeB)。提出的F-RAN架构的能量效率进行了研究,并与传统的C-RAN架构在两种不同的情况下,使用混合整数线性规划(MILP)模型进行了比较。MILP结果表明,与C-RAN架构相比,F-RAN架构可以实现平均30%的功率节省。

英文摘要:

Fog radio access network (F-RAN) and virtualisation are promising technologies for 5G networks. In F-RAN, the fog and cloud computing are integrated where the conventional C-RAN functions are diverged to the edge devices of radio access networks. F-RAN is adopted to mitigate the burden of front-haul and improve the end to end (E2E) latency. On other hand, virtualization and network function virtualization (NFV) are IT techniques that aim to convert the functions from hardware to software based functions. Many merits could be brought by the employment of NFV in mobile networks including a high degree of reliability, flexibility and energy efficiency. In this paper, a virtualization framework is introduced for F-RAN to improve the energy efficiency in 5G networks. In this framework, a gigabit passive optical network (GPON) is leveraged as a backbone network for the proposed F-RAN architecture where it connects several evolved nodes B (eNodeBs) via fibre cables. The energy-efficiency of the proposed F-RAN architecture has been investigated and compared with the conventional C-RAN architecture in two different scenarios using mixed integer linear programming (MILP) models. The MILP results indicate that on average a 30% power saving can be achieved by the F-RAN architecture compared with the C-RAN architecture.
