Data Spine: A Federated Interoperability Enabler for Heterogeneous IoT Platform Ecosystems

Abstract

Today, the Internet of Things (IoT) is pervasive and characterized by the rapid growth of IoT platforms across different application domains, enabling a variety of business models and revenue streams. This opens new opportunities for companies to extend their collaborative networks and develop innovative cross-platform and cross-domain applications. However, the heterogeneity of today’s platforms is a major roadblock for mass creation of IoT platform ecosystems, pointing at the current absence of technology enablers for an easy and innovative composition of tools/services from the existing platforms. In this paper, we present the Data Spine, a federated platform enabler that bridges IoT interoperability gaps and enables the creation of an ecosystem of heterogeneous IoT platforms in the manufacturing domain. The Data Spine allows the ecosystem to be extensible to meet the need for incorporating new tools/services and platforms. We present a reference implementation of the Data Spine and a quantitative evaluation to demonstrate adequate performance of the system. The evaluation suggests that the Data Spine provides a multitude of advantages (single sign-on, provision of a low-code development environment to support interoperability and an easy and intuitive creation of cross-platform applications, etc.) over the traditional approach of users joining multiple platforms separately.

Multi-Domain Federation Utilizing Software Defined Networking—A Review

“…8, it is not possible to create composite applications using services from different domains due to the interoperability gaps between the domains, entity interfaces, communication protocols, data formats, data models, and identity providers [148]. A recent effort in this area is Data Spine [149], a federated platform enabler that links and creates interoperability between domains. It offers the capability to federate the identity providers of various platforms, enables Single Sign On (SSO) functionality at the ecosystem level, supports interoperability between the services of various domains, and creates the technical foundation for quick, simple, and code-light development of cross-platform applications.…”
