摘要:
为了降低网络密集部署对超高吞吐率(VHT) Wi-Fi性能的影响,提出了VHT Wi-Fi基于软件定义网络(SDN)的网络架构、无线网络侧虚拟化和增强型认证与快速切换技术,以提高系统的共存性、抗干扰性和安全性。实验结果表明,VHT Wi-Fi与SDN、网络功能虚拟化、伽罗瓦/计数模式协议结合,吞吐率性能获得约10%的提升,在保证安全性同时平均切换时延降低至40 ms,可保障VHT Wi-Fi在密集部署网络中发挥重要作用。

Abstract:
In order to reduce adverse effects of the dense deployment on very high throughput(VHT) Wi-Fi performance,this paper proposes a network architecture based on software-defined networking(SDN),wireless network virtualization,the enhanced authentication and the fast handoff of VHT Wi-Fi,in order to achieve scalability,interference immunity and security.The experimental results show that the combination of SDN,network function virtualization,Galois/counter mode protocol and VHT Wi-Fi can improve throughput by 10%,ensure safety and reduce the handoff delay to 40 ms.The techniques mentioned above can ensure the role of the VHT Wi-Fi in in future dense wireless network deployments.
Key words:  very high throughput Wi-Fi  dense deployment  software-defined networking  network function virtualization  secure handoff
