A SECURE INTERNET OF THINGS MODEL USING BLOCKCHAIN WITH INTEGRATED POWER OPTIMIZATION

Wireless sensor networks (WSNs) base Internet of Things (IoT) have emerged as a pivotal technology for monitoring and collecting data in diverse applications, including environmental monitoring, industrial automation, and healthcare. However, the limited energy resources of sensor nodes present a significant challenge in ensuring the long-term sustainability and effectiveness of these networks. Energy optimization in WSNs has become a critical research focus to extend network lifetime, enhance reliability, and reduce operational costs. Security is another important issue that needs developer attention. This paper presents an implementation of blockchain security architecture for data storage and access control. A node synchronization-based energy optimization algorithm is developed and integrated into this system to enhance the lifetime of the resource-constrained IoT networks. Results after the implementation and evaluation demonstrate that the proposed model outperforms the existing models in terms of network lifetime prolonging, latency, and throughput. Use of blockchain makes the system secured for storage and authenticated accessing. Overall, the system is reliable, flexible, and robust for applications running on low-power WSNs. © 2024 by Begell House, Inc.
