Empirical Evaluation of Blockchain Based Remote Data Communication System over Wireless Sensor Network (WSN)

Abstract

The Internet of Things (IoT) concept enables the connectivity and sending and receiving of data across millions of intelligent objects. This paradigm continues to evolve and increase tremendously, just as the dangers and assaults on IoT infrastructures do. Wireless sensor networks are viewed as excellent prospects for a variety of applications, including industrial monitoring, data gathering in hazardous settings, and military operations. The technology of Blockchain has emerged in recent years as among the most revolutionary technologies. This technology was developed to facilitate digital transactions and to enable safe and trustworthy access to the distributed ledger. Blockchain technology combined with smart contracts enables users to conduct safe transactions without trusting external parties or intermediaries. Attacks and dangers are increased in centralized IoT systems, particularly when data is transferred and shared with other companies between devices. To avoid such circumstances, this study proposes a decentralized approach that ensures an IoT system’s autonomy and security. This paper addresses the recent approaches that are based on blockchain, we will review the present models and discuss their advantages and drawbacks to find out the solutions and the way to other studies.
