Haris Isakovic, Edgar Azpiazu Crespo, and Radu Grosu EAI Edge-IoT 2020 - EAI International Conference on Intelligent Edge Processing in the IoT Era A short overview on methods and technologies necessary to build smart and sustainable Internet-of-Things (IoT). It observes IoT systems in a close relation with data centered intelligence and its application in cyber-physical systems. With the current rate of growth IoT devices and supporting CPS infrastructure will reach extremely high numbers in less than a decade. This will create an enormous overhead on world's supply of electrical energy. In this paper, we propose a model extension for estimation of energy consumption by IoT devices in the next decade. The paper gives a definition of CPS/IoT Ecosystem as a mutually codependent heterogeneous multidisciplinary structure. Further we explore a set…

Rausch, T., Hummer, W., Stippel, C., Vasiljevic, S., Elvezio, C., Dustdar, S., & Krösl, K. 2021 IEEE Conference Virtual Reality and 3D User Interfaces Abstracts and Workshops In this paper, we present CognitiveAR: a platform that makes it easier for AR engineers to develop scalable cognitive assistance applications. Figure 1 shows the overall architecture. The platform federates distributed edge resources to run our platform services,and autonomously manages application-specific services for, e.g.,offloading AI-based video processing. Moreover, the platform provides transparent access to sensor data published by edge nodes, via a scalable messaging system. We introduce a global object and user tracking system which we call cyber-physical object positioning(CPOP). CPOP enables the system to accurately display the position of physical objects on the user’s device, that are not in their physical field…

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.

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

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.
