D2.3 HEDGE-IoT Reference Architecture (First Release)

This document presents the first release of the Reference Architecture for the HEDGE-IoT project, a key milestone in advancing secure, efficient, and intelligent IoT-Edge service deployment integrated with the Data Space paradigm. The Horizon 2020 HEDGE-IoT project aims to create a next-generation edge-to-cloud continuum digital infrastructure that addresses the unique challenges of heterogeneous IoT-Edge environments—combining real-time responsiveness, data privacy, interoperability, security and scalability. HEDGE-IoT introduces an innovative Digital Framework conceptualized by the Proposed Reference Architecture designed to leverage IoT assets and Edge Services across multiple layers of the energy system—from behind-the-meter installations to the Transmission System Operator level. The framework enhances intelligence at both edge and cloud layers by leveraging advanced AI and machine learning tools, while bridging the cloud-edge continuum through federated applications governed by sophisticated computational orchestration.
