SDNWisebed: A Software-Defined WSN Testbed

Abstract

Software-Defined Networking (SDN) is a promising approach to simplify the management of Wireless Sensor Networks (WSNs). Many SDN frameworks for WSNs have been proposed, while real-world testbeds to accelerate the development of SDN-based WSN applications are still rare. In this work, we propose SDNWisebed: an SDN-empowered WSN testbed management system that enhances the WSN management functions with a stateful Software-Defined Networking solution. This testbed was designed to evaluate various types of SDN-based WSN applications and enhance their performance, such as WSN routing protocols and network applications, before deploying them in real-world infrastructures. To validate its efficiency, we conducted both functional and performance evaluation. Real-world experiment results show that the speed of integration of new SDN applications can be improved thanks to the stateful feature awareness of SDNWisebed.
