This paper explores the integration of blockchain technology into Fog-IoT systems to optimize resource allocation and enhance security. Fog computing, by bringing computation and storage closer to IoT devices, addresses the latency and bandwidth issues faced by cloud-based systems. However, managing resources and ensuring secure interactions in a decentralized, multi-device environment remains a challenge. Blockchain, with its decentralized ledger and smart contract functionality, offers a promising solution for overcoming these challenges. By utilizing blockchain, resource allocation in Fog-IoT systems can be automated, transparent, and efficient, without relying on a central authority. Smart contracts enable dynamic and fair distribution of resources, ensuring that each IoT device receives the necessary computation and storage. Furthermore, blockchain enhances security by providing cryptographic protection, secure data transmission, and decentralized authentication mechanisms, safeguarding the IoT network from potential cyber threats. The paper also compares the performance of the proposed blockchain-based architecture with traditional fog computing models, focusing on key metrics like latency, energy consumption, transaction throughput, and resilience to security risks. The integration of blockchain into Fog-IoT systems represents a significant step towards creating more scalable, efficient, and secure IoT infrastructures, particularly for applications in smart cities, healthcare, and industrial automation.
