Software defined wireless network testbed using Raspberry Pi of switches with routing add-on

In this demo, we implement a realtime testbed for Software Defined Wireless Networks (SDWN) by using Raspberry Pi as OpenFlow (OF) Switches. The implemented testbed provides practical development and testing environment for SDWNs. Moreover, we use OpenDayLight to observe the flows and events in the network. With OpenDayLight integration, we easily provide detailed analysis results for any testing process. Additionally, we develop a traffic aware routing algorithm add-on which manages the flows w.r.t. their QoS requirements. Finally, we physically implement the proposed routing algorithm to our testbed and validate the improvements of traffic aware routing such as controller response time and network utilization.
