CPS/IoT Ecosystem: Indoor Vertical Farming System

Isakovic Haris , Alexander Fasching , Lukas Punzenberger, Radu Grosu Building large-scale IoT applications requires enormous infrastructural support. As infrastructure we understand hardware, software and communication channels necessary to ensure interconnection between various heterogeneous components. Project CPS/IoT Ecosystems explores infrastructural requirements for large-scale applications. The applications are realworld scenarios such as smart parking, smart agriculture or smart buildings. In this paper we explore infrastructural requirements necessary to build modular indoor vertical farming system. The proposed prototype is a service-oriented platform distributed over three scopes of operation: cloud, fog, sensor/actuator.

Sensyml: Simulation Environment for large-scale IoT Applications

News, Publications

Isakovic Haris, Vanja Bisanovic, Bernhard Wally, Thomas Rausch, Denise Ratasich, Schahram Dustdar, Gerti Kappel, Radu Grosu IoT systems are more and more becoming part of civil and industrial infrastructure. With the growth of these IoT ecosystems, their complexity is increasing exponentially. This paper reflects on issues with respect to scalability in these systems. A simulation framework is proposed, that is capable of generating big data, to evaluate scalability of IoT infrastructures and correspondent applications. It is a cloud based Infrastructure as-a-Service (IaaS) system that enables users to test both functionality and scalability of their IoT applications. IEEE/IES IECON 2019, September 2019, Lisbon. PT

Demo: A System for Operating Energy-Aware Cloudlets

News, Publications

Thomas Rausch, Philipp Raith, Padmanabhan Pillai, Scharam Dustar This work was presented at the 4th ACM/IEEE Symposium on Edge Computing and was awarded with best demo award. Congrats to the team led by Thomas Rausch. We present an end-to-end system for operating energy-aware cloudlets with a low-footprint cluster manager and an adaptive client-side load balancing approach. Our system is designed for small-scale high-density compute clusters that host stateless services and have stringent energy resource constraints. It features cluster and service management, runtime monitoring, adaptive load balancing and cluster reconfiguration policies. Furthermore, we present an experimentation and analytics system that allows coordinated execution of complex workload experiments to evaluate different operational strategies.

CPS/IoT Ecosystem: Preparing Austria for the Next Digital Revolution

News

Radu Grosu, Schahram Dusdtar, Gerti Kappel, Tom Henzinger, Manfred Gruber, Hermann Kopetz Looking back at the time Bill Gates was one of his brilliant students, Christos Papadimitriou a Harvard professor and world-renowned computer scientist, concluded that one of the greatest challenges of the academic community is to recognizing when an IT revolution is on its way. He did not see the PC revolution coming, but his student did. Since then several others happened, such as the Internet and the Mobiles revolutions. Another imminent one is in the making: The CPS/IoT revolution. The worldwide academic institutions and especially the Austrian ones have a responsibility to ask the following important questions: Are we prepared for the CPS/IoT revolution? Do we have the proper infrastructure, software tools and courses? The answer is unfortunately…

A Roadmap Towards Resilient Internet of Things for Cyber-Physical Systems

Publications

The Internet of Things (IoT) is an ubiquitous system connecting many different devices -- the things -- which can be accessed from the distance. With the possibility to monitor and control the physical environment from the distance, that is the IoT contains cyber-physical systems (CPS), the two concepts of dependability and security get deeply intertwined. The increasing level of dynamicity, heterogeneity, and complexity adds to the system's vulnerability, and challenges its ability to react to faults. This paper summarizes state-of-the-art of existing surveys on anomaly detection, fault-tolerance and self-healing and adds a number of other methods applicable to achieve resilience in an IoT. We particularly focus on non-intrusive methods ensuring data integrity in the network. Furthermore, this paper presents the main challenges to build a resilient IoT for CPS. It…

High-School Student Laura Flandorfer talks about her Internship at TU Wien

News

Laura Flandorfer, a student at the computer engineering branch of the Hertha Firnberg Schools in Vienna, got to know research and science as part of her internship sponsored by the FFG. At the Cyber-Physical Systems Research Division she developed a pick & place machine to equip circuit boards with electronic components. For this she had to design 3D printed parts, assemble the electronics an program the machine. The interview is also featured on the faculty's website.

CPS/IoT Ecosystem: A platform for research and education

Publications

In this paper we explain basic idea behind CPS/IoT Ecosystem its effects on research and education. The CPS/IoT Ecosystem project aims to build an IoT infrastructure that will be used as a platform for research and education in multiple disciplines related to CPS and IoT. The main objective is to provide a real-world infrastructure, and allow students and researchers explore its capabilities on actual use cases.

EMMA: Distributed QoS-Aware MQTT Middleware for Edge Computing Applications

Publications

Publish–subscribe middleware is a popular technology for facilitating device-to-device communicationin large-scale distributed Internet of Things (IoT) scenarios. However, the stringent quality of service (QoS) requirements imposed by many applications cannot be met by cloud-based solutions alone. Edge computing is considered a key enabler for such applications. Client mobility and dynamic resource availability are prominent challenges in edge computing architectures. In this paper, we present EMMA, an edge-enabled publish–subscribe middleware that addresses these challenges. EMMA continuously monitors network QoS and orchestrates a network of MQTT protocol brokers. It transparently migrates MQTT clients to brokers in close proximity to optimize QoS. Experiments in a real-world testbed show that EMMA can significantly reduce end-to-end latencies that incur from network link usage, even in the face of client mobility and unpredictable resource availability.
