Research on progress of SDN in wireless networks

分析了SDN(Software Define Network)技术在无线网络中的研究进展,描述了基于SDN的5G网络体系架构,这种网络架构可以提高网络的利用效率并保障用户业务体验。着重介绍了一种在无线SDN框架中基于应用程序的Qo S(Quality of Service)控制方法,并以云业务为例,将该方法与现有的控制方法进行比较,结果表明这种方法能够有效减少能量消耗,保证用户Qo S。

A research on the progress of SDN （Software Define Network） in wireless networks is presen- ted. This paper gives a description of 5G network architecture based on SDN which can improve network efficiency and service experience. Besides ,an application based scheme is designed to control QoS（ Quali- ty of Service） in the wireless SDN framework. Cloud computing services are taken as examples in the comparison between the proposed scheme and the scheme can effectively reduce energy consumption existing schemes. The results show that the proposed and ensure users＇ QoS.
