A blockchain-based adaptive middleware for large scale internet of things data storage selection

Abstract

IoT applications with massive generation of data have different service requirements in terms of performance, security, privacy, availability and price. Relying on a single cloud storage puts limits on the applications, which could be alleviated by another storage solution. Moreover multi-cloud storage architecture has limited impact due to the lack of differentiation between competing cloud solutions. Recently, decentralized storage solutions are gaining attraction as an alternative to cloud storage. In this work, we propose a blockchain-based adaptive middleware for intelligent selection of storage technology for IoT applications and explore the open questions regarding the integration of middleware with IoT applications, storage technologies and blockchain network.
