Sotware-Defined Networking for Internet of Things: Rule Placement and Routing


The software-defined networking (SDN) technology enables real-time programmability of network devices by decoupling control- and data-planes. Thus, the complexity involved in managing networks is reduced significantly compared to that of the traditional networks. Although different SDN-based approaches exist in the literature, they either focus on the traditional networking issues or are at their infancy to be integrated into fully programmable networks to provide differentiated service provisioning for IoT applications. In this talk, adaptive rule-placement and routing strategies to satisfy heterogeneous quality-of-service (QoS) requirements of traffic from sensors and network devices in SDN-enabled end-to-end IoT networks will be discussed. Further, the scalability issues with a single SDN controller in the presence of a large number of flows in the network will be discussed, and a dynamic controller assignment scheme will be presented to mitigate the scalability issues.
