Abstract

The rapid growth of the Internet of Things (IoT) has introduced complex challenges related to scalability, interoperability, and efficient management of heterogeneous networks. This paper presents a novel architecture that integrates Software Defined Networking (SDN) and Network Function Virtualization (NFV) to enhance the management and operation of IoT infrastructures. The proposed framework introduces a three-layer model—Application, Control, and Infrastructure—where NFV enables dynamic service deployment, and SDN provides centralized control and programmability. Extensive performance evaluations demonstrate significant improvements: a 30-40% reduction in end-to-end latency for local processing scenarios, consistent throughput under varying device loads, and over 95% QoS compliance for critical traffic flows. Resource utilization remains minimal, with VNFs consuming less than 15% CPU under moderate traffic loads. These results validate the architecture’s effectiveness in c
