“…The idea of Thin APs with a centralized controller has recently been introduced into academia as well as industry [1]- [9]. However, current studies [1]- [5] only solve AP management issues individually, which cannot offer a complete solution for large-scale Wi-Fi networks. Furthermore, additional protocols and software agents are needed in such solutions.…”

Large-scale Wi-Fi networks have encountered several critical issues of access point (AP) management such as manual configuration, channel interference, and unbalanced loads, which should be carefully addressed to ensure efficient system performance. Since most of the commercial Wi-Fi products are proprietary and hardware-dependent, some recent studies have aimed at introducing open and programmable solutions. Unfortunately, the studies demand additional protocols and software agents but cannot provide complete solutions. To this end, this experience paper presents the design, prototype implementation, and evaluation of SAMF, which is an open, programmable, and generic framework for access point management in large-scale Wi-Fi networks. By adopting the concept of SDN technology and OpenFlow protocol, SAMF can readily be deployed on low-cost commodity access point hardware and a cloud-based controller, while enabling new network services to be integrated rapidly. Furthermore, experimental results confirm that the framework can significantly reduce operational costs since it accelerates the AP configuration process by approximately 15 times. Besides, SAMF can increase system throughput up to 26.5% and improve the balanced degree of the system by about 40%.

Software Defined Networking (SDN) is an emerging architecture which decouples networks control plane and data plane physically. It makes control plane programmable trough a centralized controller, and builds intelligent and flexible networks. The OpenFlow is one of the most famous SDN protocols, which acts as a southbound interface between control plane and data plane. In this survey, SDN implementation approaches and different southbound interfaces, beside different version of OpenFlow, are introduced. In addition to general architecture of SDN, different wireless architectures are discussed. Here, also potential SDN's applications and research areas including hot topics such as Information Centric Networks, Cloud and datacenters, multimedia, wireless and mobile networks over SDN are reviewed.

“…An integration work featuring OpenFlow and wireless IEEE ICC 2014 -Next-Generation Networking Symposium 978-1-4799-2003-7/14/$31.00 ©2014 IEEE networks is being conducted by the group that proposed OpenFlow [5] [6], which, by extending SNMP into the OpenFlow Controller, allows the control of power, frequency, data rate, SSID, etc., and to capture wireless events, such as detecting the association of a host with an Access Point. The use of OpenFlow in Wireless Mesh Networks is also being subject of study [7] [8].…”

The evergrowing availability of access technologies, on-line services and connected devices has been motivating the development of novel networking solutions, fostering new deployments of cloud computing, Network Function Virtualization and even mobile accesses. One of the core aspects supporting these innovative solutions is the Software Defined Networking (SDN) concept, which brings added configuration and management capabilities to the network fabric, aiding the support and introduction of new technologies and protocols. However, the base operations of SDN do not consider link conditions when employing their controlling mechanisms and mostly target fixed core links. These link conditions are important to optimizations involving wireless access links, which are paramount in today's plethora of wireless and mobile accesses. This paper enhances SDN mechanisms with Media Independent Management capabilities, deployable in both wired and wireless environments, optimizing link connectivity establishment and offering new perspectives to network developers for building new capabilities in the networks. The resulting framework was implemented over open-source software in a physical testbed, with results showing the benefits that this solution brings in terms of path optimization, featuring different monitoring schemes and allowing energy efficient scenarios.
