“Blockchain for Internet of Things: Data Markets, Learning, and Sustainability”

In this decade, the Internet of Things (IoT) has penetrated many aspects of the physical world to realize different applications. Through IoT networks, the applications can collect, exchange, generate, analyze, and aggregate a vast amount of security-critical and privacy-sensitive data. The data collected from IoT devices can have significant economic value for stakeholders. However, the way the data from the standard IoT system is gathered and collected raises concerns about data integrity, trust, security, transparency, and public availability. These data can be both public and private, which makes it difficult to validate their origin and consistency. Moreover, given the potential value of IoT data, mechanisms must be designed for a reliable and trustworthy data exchange among participants, which are not necessarily trustworthy.

The objective of this research is to utilize DLTs towards designing innovative decentralized solutions for wireless IoT networks, which can guarantee trust, transparency, and privacy of IoT data collection, storage, and trading. In addition, trusted cooperative frameworks are introduced to allow IoT data to be monitored, accounted, and traded among involved participants in order to maximize the utility of IoT data. The proposed innovative solutions include: i) A collaborative framework to design scalable, trusted, and cost-efficient IoT monitoring systems; ii) A framework to evaluate data trading protocols in distributed marketplaces based on communication and computation overhead; iii) The definition and evaluation of two novel use cases, namely, CO2 emission trading and shared manufacturing using the developed design and evaluation frameworks. The results highlight the relevance of these use cases and outline steps for future implementations.
