ABSTRACT
As the Internet of Things (IoT) rapidly evolves, a large amount of data is generated. However, data loss and network security problems are caused by traffic congestion due to selecting the best or shortest path for transmission in the general network. Therefore, to solve the above problems, a novel network architecture, called Software-Defined Network (SDN), is proposed. The SDN uses the controller and Openflow protocol to divide the routes into a control plane and a data plane. In the SDN, we can adopt multipath to deal with a large amount of IoT data without changing the number of hardware devices. Therefore, in this paper, a SDN architecture consisting of Segment Routing (SR), multipath routing, and weight-based priority mechanisms is proposed to transmit IoT data with. We expect that the performance of IoT data transmission in the future can achieve efficient traffic management, bandwidth usage, and quality of service by mininet simulation.
