A scAlable versaTile pLaTform for interconnecting heterogeneous cyber-physic Al components and Services

Users of the platform

ATLAS is an open CPS platform which brings together different types of CPS stakeholders such as service providers, technology providers, end-users and researchers.

The architecture of ATLAS offers homogeneous support to a wide range of WSN communication technologies while being able to adjust to any application or platform specifications. Additionally, the whole architecture is implemented based on commercial off-the-shelf equipment thus demonstrating the infrastructure's degree of feasibility.

Architecture of ATLAS

Driven by the necessity for holistic solutions, ATLAS is a system wide, end-to-end CPS platform the architecture of which offers critical advantages, features and services that are able to support effectively a wide range of real application scenarios. Based on message passing communication technology and utilizing Commercial-Of-The-Shelf (COTS) technologies, the proposed architecture is implemented offering an abstraction layer that effectively hides all technology heterogeneity and/or peculiarities.

Two main aspects of the ATLAS platform include: (a) performance robustness and efficiency (in terms of being able to meet demanding application requirements), and (b) resource consumption, which is critical for incorporating the proposed architecture in real cyberphysical systems. Finally, the high degree of configurability, extendibility and scalability comprise also important aspects taken into consideration during design and implementation. The implemented architecture includes wireless sensor networks as the last mile of a complete CPS system, but it also considers backend aspects such as network coordination, storage facilities and end-user interfaces. All these aspects constitute a complete, efficient and versatile novel architecture that effectively addresses the aforementioned requirements. Additionally, the proposed architecture has been evaluated considering different WSN communication technologies and workload patterns exhibiting, in all cases, time constrained and robust behaviour. Furthermore, resource requirements have been measured revealing rather conservative demands, which can be easily met by most COTS embedded platforms.
