Abstract
The quick evolution of the Internet of Things (IoT) has triggered unprecedented demands of the secure, scalable, and efficient network systems. The traditional networks lack the scalability and robustness to handle large-scale IoT networks, and Software-Defined Networking (SDN) is a promising approach. The present paper will establish a secure and efficient SDN structure that is appropriate in the work of the IoT. It examines weaknesses and limitations of existing SDN infrastructures concerning the issue of scalability and security in the first place. Second, efficiency related concerns like latency, load balancing and energy optimization are discussed. A descriptive research design that relies on the secondary data sources, including peer-reviewed literature, case studies, and technical reports are used. The paper follows the positivist philosophy and deductive reasoning to prove the hypothesis that the existing SDN frameworks do not sufficiently address the requirements of the Internet of Things. According to results, a new model of combining modern security measures and resource-efficient mechanisms is offered. The improved performance, reliability, and scalability of the framework are assessed comparatively. They have found use in smart cities, healthcare, industrial IoT and intelligent transportation systems. The model will guarantee the counter of the threat and defense against cyber attacks and at the same time be efficient and efficient enough to serve as a solution to future IoT-based infrastructures.
