glue.things: a Mashup Platform for wiring the Internet of Things with the Internet of Services

Internet of Things (IoT) is a trending topic. Market analysts predict a large growth of the entire IoT market with an explosion of new products. In this paper, we argue how the data of these devices can be connected in an efficient and extensible way. For this purpose, we present glue.things a mashup platform for wiring data of Web-enabled IoT devices and Web services. The work carried out in this paper addresses concepts and technologies that are referred as web-friendly IoT technologies. We elaborate aspects of device integration, real-time communication and data stream mashups. These aspects are discussed on features and technologies of the prototype implementation glue.things.

Towards a Multi-screen Application Model for the Web

The ever-growing ubiquity and power of mobile devices and the trend of televisions becoming more than just dumb displays for moving images are two sides of the same coin. Both types of devices have outgrown their original purpose and are now used for tasks that previously required a PC or laptop. At the same time, users often own and use multiple devices in parallel, e.g. when watching TV or while working. Traditional application models are however focused on single devices and screens, although Apps for the second screen have been getting a lot of interest recently. In this paper we propose a new approach for designing and developing multi-screen applications using standard web technologies and outline how to enable traditional web applications to become multi-screen-ready.

I-centric services based on super distributed objects

The vision of pervasive computing and communication will shape individual lives in the future. Following this vision, the goal of I-centric services based on super distributed objects is to provide a seamless computing environment on the basis of users individual communication spaces. It controls and manages large numbers of autonomous and decentralized objects (super distributed objects), in individual living or working spaces providing services that can adapt to users individual requirements (I-centric services). This paper introduces the I-centric communications approach and identifies the requirements and design of super distributed objects as the paradigm for future pervasive and autonomous systems. Results of this project have been adopted by the World Wireless Research Forum (WWRF) and Object Management Group (OMG).

Towards a remote launch mechanism of TV companion applications using iBeacon

TV sets and companion devices (Smartphones, Tablets, etc.) have outgrown their original purpose and are now playing together an important role to offer the best user experience on multiple screens. However, the collaboration between TV and companion applications faces challenges that go beyond traditional single screen applications. These range from discovery, wake-up and pairing of devices, to application launch, communication, synchronization and adaptation to target device and screen size. In this position paper, we will limit ourselves to the Remote Launch aspect and introduce an idea for a new mechanism for launching companion applications using iBeacon technology.

Next Generation Mobile Service Infrastructure Mapping to IMS

This work describes the mapping of a next generation mobile service infrastructure to the IP Multimedia Subsystem (IMS). In the IST project MobiLife, a service infrastructure for the provisioning of next generation mobile services was specified, that supports service adaptation, context awareness, personalization, privacy and trust, operational management and miscellaneous features for service provisioning. This service infrastructure specification is represented by the MobiLife reference model. IMS on the other hand is an industrial relevant platform for telecommunication service provisioning and defines beside the core platform a set of service enablers. The mapping analysis presented here supports in applying the MobiLife service infrastructure to an existing IMS for telecommunication providers. First, the MobiLife reference model is introduced. Then, two possible mapping approaches are discussed, and the mapping of some MobiLife functions to IMS functionalities is described.

Towards a wake-up and synchronization mechanism for Multiscreen applications using iBeacon

TV sets and companion devices (Smartphones, Tablets, etc.) have outgrown their original purpose and are now playing together an important role to offer the best user experience on multiple screens. However, the collaboration between TV and companion applications faces challenges that go beyond traditional single screen applications. These range from discovery, wake-up and pairing of devices, to application launch, communication, synchronization and adaptation to target device and screen size. In this position paper, we will limit ourselves to two of these aspects and introduce an idea for a new wake-up and synchronization mechanism for Multiscreen applications using iBeacon technology.

Life Cycle Management of Personalized and Context-aware Services in Mobile Networks Environment

As an essential part of mobile service-orientated computing, life cycle management allows service providers (SPs) and mobile network operators (MNOs) to manage services provisioning, launch new service offers, maintain them, and, finally, to withdraw them or improve them. This is vital because services are launched rapidly and life cycle steps are becoming shorter. To address this need, this paper proposes services life cycle management interfaces for context-aware services. SPs need automated mechanisms that conform to the standard practices and emerging requirements of the mobile industry. Since context-awareness and personalized features add agility to mobile services, they must be reflected in the life cycle management, which is one of the strong themes in this paper and novelty of the interfaces presented. Key stakeholders and their requirements are analyzed. Analysis results are used as a guide for the development of interfaces. Therefore the work is readily adaptable in a real-life situation

Life Cycle Management of Personalized and Context-aware Mobile Services - Goals, Requirements and Interfaces

This paper proposes key requirements and interfaces for the management of life cycle of context-aware and personalized mobile services. The main rationale behind the work presented here is that the service management component should be designed in such as a way that life cycle aspects should emerge from within service management components themselves as an integral part of overall services management. The features of context-aware applications and services should be reflected in life cycle management. Furthermore, standard practices of the mobile network industry must be taken into account for any serious effort to deal with this issue. All these aspects have guided and provided impetus for the work presented. Therefore this work is easily applicable in industry applications and proposes a clear-cut association between requirements and interfaces

Towards I-centric business communication tools

The vision of I-centric communications is one of the important and well-known paradigms for future ubiquitous user-centric services. Following this vision, the goal of the research project I-centric business communication tools (ICBCT) is to realize a seamless computing environment and supporting tools for mobile workers and users. Context awareness, personalization, adaptation as well as communication support are identified as key features of the envisioned platform. The tools were implemented using YACAN (yet-another context awareness), which is a context awareness framework developed by NTT DATA. During the course of the project, YACAN are enhanced with features derived from the I-centric communications approach. This paper introduces the functional building blocks as well as the logical architecture of the resulting ICBCT platform. Based on this architecture two service scenarios was shown.

Towards a high efficient 360° video processing and streaming solution in a multiscreen environment

Immersive video has been around for some time but only recently the technology became more popular since affordable cameras with sufficient resolution as well as stitching software with reasonable quality became available to allow professionals and interested amateurs to create 360° movies. Networks became fast enough to allow end-users to stream 360° video content to their devices. Hardware on TVs, smartphones and tablets is sufficiently powerful to handle the content and react on view changes without noticeable delay. Most efforts in this area, however, have been aimed at the technical challenges creating and viewing of 360° content. As 360° video is starting to reach a wider audience, the need arises to pay attention to the use of such content in a realistic commercial environment. For this, two issues need to be addressed. The efficient distribution of 360° content and the added-value that it can bring content providers. We will address in this paper two main challenges a) the efficient streaming of high quality 360° video content using existing content delivery networks (CDNs) and without the need for additional bandwidth comparing to traditional video streaming and b) the playback of 360° content even on devices with limited processing resources and programmatic capabilities.
