Integration of Blockchain Technology with Wireless Sensor Networks for Enhanced IoT Security

Abstract

The combination of Blockchain Technology and Wireless Sensor Networks (WSNs) offers a promising solution to bolstering security within the Internet of Things (IoT). WSNs, known for their limited resources and susceptibility to cyber threats, stand to benefit from blockchain's decentralized and immutable characteristics. This article examines the security challenges prevalent in IoT deployments and explores blockchain's potential to address these issues specifically in WSN contexts. Various methods of integrating blockchain, including consensus mechanisms and data integrity verification, are explored. Case studies demonstrate practical applications of blockchain-integrated WSNs across different sectors, illustrating enhanced security and operational effectiveness. Evaluation metrics are analyzed to gauge the impact of blockchain integration, comparing it with traditional security methods. The article concludes by outlining future research directions and highlighting blockchain's capacity to revolutionize IoT security through improved data integrity, authentication mechanisms, and decentralized trust protocols.
