Abstract. The paper proposes network architecture based on software-defined networking (SDN), wireless network virtualization, the enhanced authentication and the fast handoff to achieve scalability, interference immunity and security, aiming to reduce adverse effects of the dense deployment on the performance of very high throughput (VHT) Wi-Fi. 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%, which is able to maintain security while reducing the handoff delay to 40ms. The techniques mentioned above can guarantee the role of the VHT Wi-Fi in future dense deployment wireless networks.
