I-Centric Communications

Diese Arbeit beschreibt die Vision I-centric Communications ein neues Paradigma für zukünftige Telekommunikationssysteme. Das Hauptziel dieses Ansatzes ist es das menschliche Kommunikationsverhalten und nicht die Technologien die typischerweise zur Kommunikation eingesetzt werden, als Ausgangsbasis für den Entwurf von Telekommunikationssystemen zu benutzen. Daher konzentriert sich diese Arbeit auf die konzeptionelle Integration aller für I-centric Communications notwendigen Aspekte. Untersucht man das Kommunikationsverhalten von Menschen näher, wird klar, dass Menschen regelmäßig mit einer bestimmten Menge von Objekten in ihrer Umgebung interagieren um ihre täglichen Probleme zu lösen. Diese Erkenntnis kann als Grundlage für den Entwurf von Telekommunikationssystemen dienen. Der Entwurf stützt sich dabei nicht auf spezifische Telekommunikationstechnologien sondern auf die Analyse individueller Kommunikationsräume. Das Resultat eines solchen Entwurfs ist ein Telekommunikationssystem, dass sich an die individuellen Anforderungen eines jeden Menschen anpasst (I-centric). Das Kommunikationssystem agiert im Sinne des Benutzers, protokolliert wiederkehrende Aktionen, um sich selbst den Bedürfnissen des Benutzers weiter anzupassen. Die beschriebene Funktionalität erfordert eine intelligente Diensterbringung im Hinblick auf die Personalisierung von Diensten, der Adaption an situationsbedingte oder umgebungsabhängige Einflüsse, und der Überwachung bzw. Steuerung von individuellen Kommunikationsräumen. Kommunikationssysteme die dieser Idee folgen müssen individuelle Kommunikationsräume modellieren und verwalten um sich an die persönlichen Interessen, Umgebungen und Präferenzen anpassen zu können. Diese Arbeit beginnt mit der Vorstellung der Vision I-centric Communications , gefolgt von der Entwicklung eines entsprechenden Referenzmodells. Im Anschluss wird auf der Basis des Referenzmodells eine Architektur zur Implementierung von I-centric Kommunikationssystemen entwickelt. Die Vorstellung einer der Architektur folgenden Implementierung schließt diese Arbeit ab. Die Forschungsarbeit im Bereich I-centric Communications wurde in Kooperation zwischen dem Lehrstuhl für Offene Kommunikationssysteme (OKS) der Technischen Universität Berlin (TUB) und dem Fraunhofer Institut FOKUS durchgeführt. Die Vision sowie das Referenzmodell für I-centric Communications , die in der vorliegenden Arbeit vorgestellt werden, sind Ergebnisse dieser Kooperation. Die Forschungsschwerpunkte der Kooperation zwischen TUB und FOKUS waren das Generelle Modell für I-centric Dienste , die Dienstplattform für I-centric Dienste sowie die Interaktion zwischen Nutzern und I-centric Diensten . Die vorliegende Arbeit konzentriert sich auf das generische Model für I-centric Dienste und entsprechende Dienstplattformen. Aspekte der individuellen Benutzerinteraktion werden nicht betrachtet. Diese Aspekte wurden in einer zweiten Dissertation von Stephan Steglich, TUB, analysiert und ausgearbeitet. Die Ergebnisse dieser Dissertation wurden in verschiedenen nationalen und internationalen Forschungsprojekten (BMBF: LiveFutura, VHE-UD, PI-AVIda, IST: WSI, WWRI), Standardisierungsgremien (OMG, WWRF), Konferenzpapieren sowie Zeitschriften eingebracht, um die Vision von I-centric Communications einem größeren Auditorium vorzustellen.This thesis describes the vision of I-centric communications a new paradigm for future telecommunication systems. The main objective of this approach is to consider the human communication behavior, not the technologies that support communication, as the starting point for the design of telecommunication systems. The focus of this thesis is on the conceptual integration of all aspects of I-centric communications. Looking at the communication behavior of human, it is obvious, that human beings frequently interact with a set of objects in their environment. Following this view, a new approach is not to build communication systems based on specific technologies, but on the analysis of the individual communication space. The result is a communication system that adapts to the demands of each individual (I-centric). The communication system will act on behalf of human s demands, reflecting recent actions to enable self-adaptation. I-centric Services adapt to individual communication spaces and situations. In this context I means I, or individual, Centric means adaptable to I requirements and the individual s environment. The rationales above require intelligence in service provisioning in order to personalize, adapt to situational and environmental conditions, to monitor and to control the individual communication space. An I-centric communications system will provide the intelligence required for modeling the communication space of each individual adapting to its interests, environment, and preferences. The thesis introduces the vision of I-centric communications, followed by the development of a reference model for I-centric communications. Since both, the vision and the reference model, are general, an architectural framework for I-centric communications is introduced later on. This framework is used to design and implement an I-centric communications system. The work in the area of I-centric communications was carried out in cooperation of the Department for Open Communication Systems (OKS) at the Technical University Berlin (TUB) and the Fraunhofer Institute FOKUS. The vision and the reference model, introduced in this thesis, are the results of this cooperation. The main research directions for the cooperation between TUB and FOKUS have been a general model for I-centric Services, the service platform for I-centric Services, and an approach for the interaction of users with I-centric Services. This thesis focuses on I-centric Services and according communication system. The aspects of user interaction are out of scope of this thesis. Nevertheless, these aspects have been analyzed by Stephan Steglich, researcher at the TUB, in a second PhD thesis in parallel. The results of this thesis have been contributed to different national and international projects (BMBF: LiveFutura, VHE, PI-AVIda, IST: WSI, WWRI), standardization bodies (OMG, WWRF), conference papers, and journals by introducing the vision of I-centric communications to a larger auditorium, and by exploiting parts of the developed I-centric systems

Integration of ICN and MEC in 5G and beyond networks : mutual benefits, use cases, challenges, standardization, and future research

Multi-access Edge Computing (MEC) is a novel edge computing paradigm that moves cloudbased processing and storage capabilities closer to mobile users by implementing server resources in the access nodes. MEC helps fulfill the stringent requirements of 5G and beyond networks to offer anytimeanywhere connectivity for many devices with ultra-low delay and huge bandwidths. Information-Centric Networking (ICN) is another prominent network technology that builds on a content-centric network architecture to overcome host-centric routing/operation shortcomings and to realize efficient pervasive and ubiquitous networking. It is envisaged to be employed in Future Internet including Beyond 5G (B5G) networks. The consolidation of ICN with MEC technology offers new opportunities to realize that vision and serve advanced use cases. However, various integration challenges are yet to be addressed to enable the wide-scale co-deployment of ICN with MEC in future networks. In this paper, we discuss and elaborate on ICN MEC integration to provide a comprehensive survey with a forward-looking perspective for B5G networks. In that regard, we deduce lessons learned from related works (for both 5G and B5G networks). We present ongoing standardization activities to highlight practical implications of such efforts. Moreover, we render key B5G use cases and highlight the role for ICN MEC integration for addressing their requirements. Finally, we layout research challenges and identify potential research directions. For this last contribution, we also provide a mapping of the latter to ICN integration challenges and use cases

Digitising the Industry Internet of Things Connecting the Physical, Digital and VirtualWorlds

This book provides an overview of the current Internet of Things (IoT) landscape, ranging from the research, innovation and development priorities to enabling technologies in a global context. A successful deployment of IoT technologies requires integration on all layers, be it cognitive and semantic aspects, middleware components, services, edge devices/machines and infrastructures. It is intended to be a standalone book in a series that covers the Internet of Things activities of the IERC - Internet of Things European Research Cluster from research to technological innovation, validation and deployment. The book builds on the ideas put forward by the European Research Cluster and the IoT European Platform Initiative (IoT-EPI) and presents global views and state of the art results on the challenges facing the research, innovation, development and deployment of IoT in the next years. The IoT is bridging the physical world with virtual world and requires sound information processing capabilities for the "digital shadows" of these real things. The research and innovation in nanoelectronics, semiconductor, sensors/actuators, communication, analytics technologies, cyber-physical systems, software, swarm intelligent and deep learning systems are essential for the successful deployment of IoT applications. The emergence of IoT platforms with multiple functionalities enables rapid development and lower costs by offering standardised components that can be shared across multiple solutions in many industry verticals. The IoT applications will gradually move from vertical, single purpose solutions to multi-purpose and collaborative applications interacting across industry verticals, organisations and people, being one of the essential paradigms of the digital economy. Many of those applications still have to be identified and involvement of end-users including the creative sector in this innovation is crucial. The IoT applications and deployments as integrated building blocks of the new digital economy are part of the accompanying IoT policy framework to address issues of horizontal nature and common interest (i.e. privacy, end-to-end security, user acceptance, societal, ethical aspects and legal issues) for providing trusted IoT solutions in a coordinated and consolidated manner across the IoT activities and pilots. In this, context IoT ecosystems offer solutions beyond a platform and solve important technical challenges in the different verticals and across verticals. These IoT technology ecosystems are instrumental for the deployment of large pilots and can easily be connected to or build upon the core IoT solutions for different applications in order to expand the system of use and allow new and even unanticipated IoT end uses. Technical topics discussed in the book include: • Introduction• Digitising industry and IoT as key enabler in the new era of Digital Economy• IoT Strategic Research and Innovation Agenda• IoT in the digital industrial context: Digital Single Market• Integration of heterogeneous systems and bridging the virtual, digital and physical worlds• Federated IoT platforms and interoperability• Evolution from intelligent devices to connected systems of systems by adding new layers of cognitive behaviour, artificial intelligence and user interfaces.• Innovation through IoT ecosystems• Trust-based IoT end-to-end security, privacy framework• User acceptance, societal, ethical aspects and legal issues• Internet of Things Application

I-centric User Interaction

Die Vision I-centric Communications bedeutet, einen uneingeschränkten Blick auf das menschliche Kommunikationsverhalten zu werfen, um Kommunikationssysteme entsprechend daran angepasst zu entwickeln. Diese Vision definiert einen benutzerorientierten Ansatz zur Erstellung von Diensten und Anwendungen. Dies setzt zunächst eine Analyse der Benutzeranforderungen voraus, um geeignete Systeme und Dienste zu entwerfen. Anstatt Technologie-fokussierte Lösungen ohne jegliche Anpassung an die jeweiligen Personen anzubieten, sollte ein I-centric System seine Dienste ohne sichtbare technische Details und unter Berücksichtigung von Benutzerpräferenzen sowie der Benutzerumgebung darbieten. Der Vision von I-centric Communications folgend, stellt die vorliegende Arbeit einen Ansatz zur Realisierung der Idee von I-centric User Interaction vor. Dieser Ansatz erweitert und vervollständigt die Vision durch verbesserte Benutzerinteraktionsfähigkeiten. Diese Dissertation zeigt, dass es möglich ist, Kommunikationssysteme zu realisieren, die die Interaktion zwischen Benutzern und Diensten ohne Einschränkung auf bestimmte Technologien für Benutzerschnittstellen sowie in personalisierter und umgebungsberücksichtigende Art und Weise unterstützen. Derartig verbesserte Benutzerinteraktion wird die Akzeptanz und die Benutzung von Diensten erhöhen. Einerseits soll die Benutzerinteraktion verschiedene Arten von Technologien für Benutzerschnittstellen unterstützen, durch die die Geräte-Unabhängigkeit und der ständige Zugang zu den Diensten ermöglicht werden. Entsprechend dem aktuellem Kontext und der Absicht können die Benutzer die bevorzugte und geeignete Art der Interaktion wählen. Andererseits soll die Interaktion selbst den Benutzerpräferenzen sowie der jeweiligen Umgebung angepasst werden. Dementsprechend diskutiert die vorliegende Arbeit diese unterschiedlichen Problembereiche, identifiziert die notwendigen Funktionen und bietet entsprechende Lösungsansätze jeweils. Die Arbeit präsentiert und analysiert zunächst die Vision I-centric Communications mit Hinblick auf den Aspekt der Benutzerinteraktion. Basierend auf den identifizierten Anforderungen wurde ein Ansatz zur Realisierung von I-centric User Interaction entwickelt. Dieser Ansatz, der in dieser Arbeit vorgestellt wird, spezifiziert ein Service Adaptation Framework und einzelne Modelle für Generische Benutzerinteraktion , für Personalisierung sowie für Ambient Awareness , die sich jeweils auf die identifizierten Problembereiche konzentrieren. Abschließend präsentiert die vorliegende Arbeit Ergebnisse einer prototypischen Realisierung des dargelegten Ansatzes. Die Ergebnisse demonstrieren die Einsetzbarkeit der entwickelten Konzepte und die Erfüllung der Vision von I-centric User Interaction . Die Forschungsarbeit im Bereich I-centric Communications wurde in Kooperation zwischen dem Lehrstuhl für Offene Kommunikationssysteme (OKS) der Technischen Universität Berlin (TUB) und dem Fraunhofer Institut FOKUS durchgeführt. Die Vision sowie das Referenzmodell für I-centric Communications , die in der vorliegenden Arbeit vorgestellt werden, sind Ergebnisse dieser Kooperation. Die Forschungsschwerpunkte der Kooperation zwischen TUB und FOKUS waren das Generelle Modell für I-centric Dienste , die Dienstplattform für I-centric Dienste sowie ein Ansatz zur Interaktion zwischen Nutzern und I-centric Dienste . Die vorliegende Arbeit konzentriert sich auf den Ansatz I-centric User Interaction , der die Interaktion zwischen Nutzern und den Diensten betrachtet. Die Aspekte der I-centric Dienste werden in der vorliegenden Arbeit nicht betrachtet. Diese Aspekte wurden in einer zweiten Dissertation von Stefan Arbanowski, Fraunhofer FOKUS, analysiert und ausgearbeitet. Die Ergebnisse dieser Arbeit wurden in verschiedenen nationalen und internationalen Forschungsprojekten (BMBF LiveFutura, BMBF PI-AVIda, BMBF VHE-UD, IST WSI, IST WWRI), Standardisierungsgremien (OMG, WWRF), Konferenzpapieren sowie Zeitschriften eingebracht, um die Vision von I-centric Communications einem größeren Auditorium vorzustellen.The vision of I-centric Communications means to take an unlimited look at human communication behavior and to adapt the activities of communication systems to it. This vision defines a user-centered approach for the realization of services and applications. It requires to start analyzing user demands to design suitable systems and services. Instead of just providing technology-focused solutions without any adaptation to individuals, an I-centric system should provide services hiding technical details and considering the individual s preferences as well as the individual s environment. Following the vision of I-centric Communications, this thesis introduces an approach to realize I-centric User Interaction. This approach enhances and completes the vision by providing advanced user interaction capabilities. It answers the question whether it is possible to realize a communication system, which allows the interaction between user and services without any restriction to specific user interface technologies and in a personalized as well as ambient aware manner. Such enhanced user interaction will lead to a higher acceptance and increased usage of services. On the one hand, the user interaction shall support different kinds of user interface technologies enabling Device Independence and ubiquitous access to the services. According to their current context and intended action, users can select the preferred and suitable way of interaction. On the other hand, the user interaction shall be adapted to the user s preferences and to the user s environment. Accordingly, this work discusses these different areas of concern, identifies necessary functions, and provides suitable solutions for each. First, the thesis introduces and analyses the vision of I-centric Communications with special regard to the aspect of user interaction. Based on the identified requirements and areas of concern, an approach to realize I-centric User Interaction was developed. The approach, presented in this thesis, specifies a Service Adaptation Framework and individual models for Personalization, for Ambient Awareness, and for Generic User Interaction focusing on the respective areas of concern. Finally, the thesis illustrates the results from the prototypical implementation of the presented approach, which has been pursued in several projects in parallel. These results demonstrate the applicability of the developed concepts and the fulfillment of the vision of I-centric User Interaction. The work in the area of I-centric Communications was carried out in cooperation of the Department for Open Communication Systems (OKS) at the Technical University Berlin (TUB) and the Fraunhofer Institute FOKUS. The vision and the reference model for I-centric Communications, introduced in this thesis, are results of this cooperation. The main research directions for the cooperation between TUB and FOKUS have been a general model for I-centric services, the service platform for I-centric services, and an approach for the interaction of users with I-centric services. This thesis focuses on an approach for I-centric User Interaction. The general aspects of I-centric services as defined by the vision are out of scope of this thesis. Nevertheless, these aspects have been analyzed by Stefan Arbanowski, researcher at Fraunhofer FOKUS, in a second PhD thesis in parallel. The results of this work have been contributed to different national and international projects (BMBF LiveFutura, BMBF PI-AVIda, BMBF VHE-UD, IST WSI, IST WWRI), standardization bodies (OMG, WWRF), conferences papers, and journals by introducing the vision of I-centric Communications to a larger auditorium, and by exploiting parts of the developed I-centric systems
