Adaptive Service Dependent Secure Blockchain Model in IOT Network

This project presents a smart industrial monitoring system that integrates IoT, blockchain, and intelligent networking to ensure secure, reliable, and efficient environmental monitoring. An ESP32-based sensor network is deployed to continuously measure critical industrial parameters such as temperature, humidity, gas concentration, and dust density.The collected data is uploaded to the ThingSpeak cloud platform in real-time, enabling remote monitoring, analytics, and early detection of anomalies or hazardous conditions. To enhance security and integrity, blockchain technology is implemented to create a tamperproof distributed ledger of sensor readings, ensuring that the data cannot be altered by unauthorized users. The sensor nodes are structured into clusters, and communication is optimized using shortest path algorithms, reducing network latency and improving energy efficiency. By combining secure data handling with intelligent routing, the proposed system offers a scalable and robust solution for modern industrial automation, predictive maintenance, and safety management.
