Abstract:The application of SDN in wireless network promotes the rises of software-defined wireless networking. SDWN decouples wireless data plane and control plane, opens up wireless network programmable interface, simplifies network management, and becomes one direction of 5G developments. First, we introduce the background and development of SDWN ,and summarize the academic architectures. Then key technologies such as mobility management, dense deployment, and load balancing are given in detail. Moreover, the implements of SDWN in different scenes are analyzed. The challenges and trends are summarized in the end.
Keywords:software-defined wireless networking (SDWN)  wireless local area networks (WLAN)  softwave-defined networking (SDN)
