Abstract

Software defined wireless network(SDWN) is a wireless network architecture that separates control plane and forward plane. It can get global topology quickly and its programmable combined with resource virtualization technology can control network access dynamically. In order to solve the problem of unbalanced load in existing WLAN and handover problem caused by the hard association between mobile terminal and AP, this paper proposed a terminal multi-point association scheme based on load-aware in SDWN. This scheme improved the seamless handoff algorithm between AP based on traffic load perception. When sensing AP load, the terminal could connect multiple virtual APs to achieve dynamic diversion. Finally, it verified this scheme on an experimental platform. Experiments show that this scheme changes the relationship between the terminal and the AP one by one compared to seamlessly switching to another AP, and it effectively improves the terminal network throughput.
