Science and Technology on Communication Security Laboratory,Chengdu 61 00 41, China;2. Department of Automation,University of Science and Technology of China,Hefei 230027, China） 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 W i-F i 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 i |
