一种基于软件定义的异构无线网络设计架构

A Heterogeneous Wireless Network Based on Software Defined Method

异构无线网络凭借其综合利用多种无线通信资源的优势,成为未来无线网络研究重点。针对异构无线网络面临综合资源利用受限、组网不灵活、业务部署困难等问题,基于软件定义设计思想,提出了一种异构无线网络设计架构,通过对无线传输手段进行软件化和资源化设计,采用网络集中控制架构,实现网络资源的动态优化配置,具备更强的灵活性和业务适配传输能力。

With the capacity of combining multiple communication resources,heterogeneous wireless network(HWN)will become the main stream in the future research.This paper focuses on some key challenges(for example,the constraint on combining multiple communication resources,the inflexibility of dynamic networking,the difficulty of deploying the service)in this field,and proposes an HWN based on Software Defined Network(SDN).With the software based methods,resource based methods and the strategy of central controlling,this framework can achieve optimal distribution of the communication resources,providing good flexibility and strong service adaptability.
