Demonstrating Configuration of Software Defined Networking in Real Wireless Testbeds

Currently, several wireless testbeds are available to test networking solutions including Fed4Fire testbeds such as w-ilab. t and CityLab in the EU, and POWDER and COSMOS in the US. In this demonstration, we use the w-ilab.t testbed to set up a wireless ad-hoc Software-Defined Network (SDN). OpenFlow is used as an SDN protocol and is deployed using a grid wireless ad-hoc topology in w-ilab.t. In this paper, we demonstrate: (1) the configuration of a wireless ad-hoc network based on w-ilab.t and (2) the automatic deployment of OpenFlow in an ad-hoc wireless network where some wireless nodes are not directly connected to the controller. The configuration of OpenFlow is shown using the Fed4Fire GUI (Graphical User Interface). The automatic configuration time of OpenFlow is calculated during the demonstration. Further, data traffic is transmitted from each wireless device to another device to show that an OpenFlow network is set up correctly on the w-ilab.t testbed.
