Abstract
The rapid expansion of the Internet of Things (IoT) and its integration with edge computing has revolutionized data collection, sharing, and analysis across various domains, including smart homes, healthcare, industrial automation, and smart cities. However, this growth has introduced significant security challenges due to the decentralized and dynamic nature of IoT networks. Centralized traditional security models that are based on controlling access and defining clear perimeters of a networked organism are insufficient to protect these environments. This paper proposes a SDP architecture that breaks down the barriers of centralized implementation by built and simulated on the blockchain concept. This paper integrates the SDP which helps in dynamic policy enforcement and fine-grained access control with blockchain, which provides decentralization, immutability, and transactional transparency in implementing security provisions for IoT networks. In this study, simulation reveals the applicability of the framework on establishing secure device interactions, conducting edge and fog computations, and documenting all activities and communications in a transparent and tamper-proof manner. The practical implementation brings out the idea that the framework undergoes constant adjustment with the network changes in an effort to utilize the mechanisms in the continual protection of networks without the experience of degraded performance. These findings present a solid foundation for further development of security, scalability and reliability of IoT environments, which should offer further possibilities for the application and utilization of IoT systems in different applications.
