The Internet of Things (IoT) witnesses a rapid increase in the number of devices getting networked together, along with a surge in big data. IoT causes various challenges, such as quality of service (QoS) for differentiated IoT tasks, power-constrained devices, time-critical applications, and a heterogeneous wireless environment. The big data generated from the billions of IoT devices needs different levels of services, providing big data service based on user requirements which is one of the complex tasks in the network. Software-defined networking (SDN) facilitates interoperability among IoT devices and QoS to the differentiated IoT tasks. SDN introduces programmability in the network by the decoupling of the control plane and data plane. The decoupling of the control logic to a centralized SDN controller drastically reduces power spent on network control on the IoT devices. Also, SDN considerably reduces hardware investments. In this chapter, we focus on discussing the feasibility of using SDN in big data generated by IoT devices. We discuss the architecture of IoT, the relationship between IoT and big data, the arrival of SDN in IoT and big data, routing mechanism, and security aspects of SDN and IoT routing and the application of SDN to IoT.
