Blockchain-Driven Secure Frameworks for Data Integrity in IoT-Enabled Wireless Sensor Networks

Real-time data acquisition and its analysis has emerged as a powerful paradigm shift across numerous fields due to the ever-increasing popularity of IoT technologies that support WSNs. However, this presents us with a challenging issue, primarily because the management of such systems is decentralized and since they are generally designed to operate with scarce resources, confirming the integrity of data, enforcing security, and establishing trust is an extremely hard problem to solve. In relation to the present study, blockchain technology is explored as a possible solution to these challenges within the context of this article. To discover prior works on blockchain-based framework. The strength or advantages of the frameworks are described in terms of methodology, application as well as the weaknesses or drawbacks of each. Some of our contributions include the following: identification of areas that need improvement on existing implementations; presenting a conceptual framework; and synthesis of important assessment factors across numerous applications. The insights are meant to guide future work on actual enhancements in the design of WSN-IoT systems that are safer, more aligned with scalability, and more efficient.
