Dynamic QoS support for IoT backhaul networks through SDN

© 2018 IEEE. The Internet-of-Things (IoT) is growing significantly, becoming an integral part of daily life. The services provided by the IoT are often dynamic and driven by physical events. When certain events occur, Quality of Service (QoS) requirements for services can change. For instance, a video camera may need to transmit higher quality footage over a network when motion is detected. A flexible network is therefore required that reacts to events and re-configures itself dynamically to meet dynamic QoS constraints. In contrast to traditional networks, Software-Defined Networking (SDN) decouples the data plane and the control plane, resulting in a programmable network. Programmable networks enable the development of SDN applications that can be used to meet the dynamic QoS needs of present-day IoT applications. In pursuit of this vision, this paper presents the architecture and implementation of a framework, built with SDN, to support dynamic QoS for the IoT. We demonstrate the framework's ability to adapt to dynamic QoS requirements and its performance through experiments on a hybrid network topology.
