光纤无线融合网络(FiWi)能效改善综述

Summarization of Energy Efficiency Improvement in Fiber Wireless Access Networks(FiWi)

光纤无线宽带接入网架构(Fiber Wireless Broadband Access Network,FiWi)能随时随地为终端用户提供高质量的宽带接入服务。然而,由于大量智能设备的互联和指数级数据业务的增长,FiWi接入网也面临着高能耗的潜在挑战。针对融合FiWi接入网中无线反复重传、业务共存转发以及跨域资源整合所引发的高能耗问题,从高效频带分配、协作计算卸载以及网络虚拟化等方面介绍了国内外研究现状并进行了展望,以期在满足服务质量约束时进一步降低FiWi接入网中的能耗。

Fiber wireless broadband access network(FiWi)can provide high-quality broadband access services for end-users anytime and anywhere.However,due to the interconnection of a large number of smart devices and the growth of exponential data services,the FiWi access networks have witnessed the potential challenges caused by high energy consumption.For the key issues existing in an integrated FiWi access network including wireless repeated re-transmission,communication service coexistence forward,and cross-domain resource integration,this paper introduces the research status home and abroad,and gives expects from efficient bandwidth allocation,collaboration computation offloading,and network virtualization,in hope of further reducing the energy consumption in the FiWi access network while satisfying quality of service constraints.
