“…Under the emulation/simulation space, OpenNet [41] highlights as recent work (arguably closest to Mininet-WiFi) on combining DCE/ns-3 and the Mininet SDN emulator [12] to provide rich SDWN experimentation features by allowing the execution of external controllers and real applications at the cost of a strongly coupled solution. In addition, OpenNet does not provide high-level abstraction APIs for wireless links nor emulation of wireless nodes (e.g., access points and stations are not equipped with wireless network interfaces), and neither mechanisms to select new access points before disconnection of current link to further shorten handover latency.…”

Software-Defined Wireless Networking (SDWN) is an emerging approach based on decoupling radio control functions from the radio data plane through programmatic interfaces. Despite diverse ongoing efforts to realize the vision of SDWN, many questions remain open from multiple perspectives such as means to rapid prototype and experiment candidate software solutions applicable to real world deployments. To this end, emulation of SDWN has the potential to boost research and development efforts by re-using existing protocol and application stacks while mimicking the behavior of real wireless networks. In this article, we provide an in-depth discussion on that matter focusing on the Mininet-WiFi emulator design to fill a gap in the experimental platform space. We showcase the applicability of our emulator in an SDN wireless context by illustrating the support of a number of use cases aiming to address the question on how far we can go in realistic SDWN experiments, including comparisons to the results obtained in a wireless testbed. Finally, we discuss the ability to replay packet-level and radio signal traces captured in the real testbed towards a virtual yet realistic emulation environment in support of SDWN research.

“…Network setup: For each experiment, we rst ran the POX [19] SDN controller, then OpenNet is started. OpenNet [8] is an open source simulator for wireless SDN formed by two simulators: Mininet [20] for simulating the SDN, using OpenFlow 1.3.1 and NS3 [25] for simulating wireless networks. We used OpenNet, without any change 3 , to simulate 420 di erent con gurations with a di erent number of APs (1 to 21) in di erent locations.…”

WiFi networks are o en planned to reduce interference through planning, macroscopic self-organization (e.g. channel switching) or network management. In this paper, we explore the use of historical data to automatically predict tra c bo lenecks and make rapid decisions in a wireless (WiFi-like) network on a smaller scale. is is now possible with so ware de ned networks (SDN), whose controllers can have a global view of tra c ows in a network. Models such as classi cation trees can be used to quickly make decisions on how to manage network resources based on the quality needs, service level agreement or other criteria provided by a network administrator. e objective of this paper is to use data generated by simulation tools to see if such classi cation models can be developed and to evaluate their e cacy. For this purpose, extensive simulation data were collected and data mining techniques were then used to develop QoS prediction trees. Such trees can predict the maximum delay that results due to speci c tra c situations with speci c parameters. We evaluated these decision/classi cation trees by placing them in an SDN controller. OpenFlow cannot directly provide the necessary information for managing wireless networks so we used POX messenger to set up an agent on each AP for adjusting the network. Finally we explored the possibility of updating the tree using feedback that the controller receives from hosts. Our results show that such trees are e ective and can be used to manage the network and decrease maximum packet delay.

“…The mentioned ns-3 emulator can be considered a complementation to Mininet, or vice versa. A similar approach has been utilized to develop an OpenNet emulator, which combines the advantages of both mentioned solutions -the compatibility of Mininet and wireless networking support of ns-3 [21].…”
