Abstract

Wi-Fi technologies have attracted great attention due to the low cost of construction and maintenance. However, the explosive growth of mobile applications bring new challenges in terms of difficult service quality requirement, such as ultra bandwidth, seamless mobility and high reliability. In this paper, we propose an efficient SDN-based architecture for Wi-Fi networks, which can exploit MPTCP to enable simultaneously transmission for a specific application, and achieve fine-grade path assignment for a single subflow. To evaluate our design, we build a real-world testbed that consists of commodity AP devices, the experimental results demonstrate that our system can significantly improve the wireless throughput and reduce handover delay at the same time.
