Blockchain for WSN and IoT Applications

Abstract

This paper reviews the important application areas of blockchain in Wireless Sensor Networks (WSN) and Internet of Things (IoT) applications. We identify areas where current IoT processes can be enhanced through the use of this new technology with emphasis on the issues addressed in Wireless Body Sensor Networks. This use case is discussed in detail, identifying a suitable blockchain architecture for an industry that is averse to risk, gathering security challenges in this architecture, and providing existing blockchain solutions for these challenges.
