“…Consequently, advanced SDN architectures for various wireless networks have been proposed continually [2][3][4][5][6][7]. In addition, such architectures can be utilized for controlling relatively complex control plane of a reliable wireless infrastructure, such as an advanced routing protocol, information centric networking (ICN), and a mobile network [8][9][10][11][12][13]. If a control point of wired and wireless networks is unified, the controller can perform management of the various resources of the wireless networks as well as flow control.…”

Management of wireless networks as well as wired networks by using software-defined networking (SDN) has been highlighted continually. However, control features of a wireless network differ from those of a wired network in several aspects. In this study, we identify the various inefficient points when controlling and managing wireless networks by using SDN and propose SDN-based control architecture called Proxcon to resolve these problems. Proxcon introduces the concept of a proxy SDN controller (PSC) for the wireless network control, and the PSC entrusted with the role of a main controller performs control operations and provides the latest network state for a network administrator. To address the control inefficiency, Proxcon supports offloaded SDN operations for controlling wireless networks by utilizing the PSC, such as local control by each PSC, hybrid control utilizing the PSC and the main controller, and locally cooperative control utilizing the PSCs. The proposed architecture and the newly supported control operations can enhance scalability and response time when the logically centralized control plane responds to the various wireless network events. Through actual experiments, we verified that the proposed architecture could address the various control issues such as scalability, response time, and control overhead.
