Fog Radio Access Networks: Mobility Management, Interference Mitigation and Resource Optimization

摘要

In order to make Internet connections ubiquitous and autonomous in our daily lives, maximizing the\udutilization of radio resources and social information is one of the major research topics in future mobile\udcommunication technologies. Fog radio access network (FRAN) is regarded as a promising paradigm\udfor the fifth generation (5G) of mobile networks. FRAN integrates fog computing with RAN and makes\udfull use of the edge of networks. FRAN would be different in networking, computing, storage and\udcontrol as compared with conventional radio access networks (RAN) and the emerging cloud RAN.\udIn this article, we provide a description of the FRAN architecture, and discuss how the distinctive\udcharacteristics of FRAN make it possible to efficiently alleviate the burden on the fronthaul, backhaul\udand backbone networks, as well as reduce content delivery latencies. We will focus on the mobility management, interference mitigation, and resource optimization in FRAN. Our simulation results show\udthat the proposed FRAN architecture and the associated mobility and resource management mechanisms\udcan reduce the signaling cost and increase the net utility for the RAN.\ud\ud
