Developing an IoT Networks-based Testbed for Software-Defined Networks

As the technologies are improving every day, trillions of Internet of Things (IoT) devices are estimated to be deployed in the next five years. The challenge of connecting IoT devices are massive network traffic, high reliability, and energy constraints. In this paper, a Software-defined Network (SDN) testbed with Raspberry Pi which works as an OpenFlow switch is developed. We measure the network parameters (e.g. bandwidth, jitter, throughput) on the testbed without a load balancer and with an active load balancer. The results confirm that SDN based load balancer is useful to overcome those aforementioned challenges. This testbed will be helpful for further research on load balancing in the software-defined network.
