Über dieses Buch

The First Future Internet Symposium was held during September 28–30, 2008 in Vienna, Austria. FIS 2008 provided a forum for leading researchersand pr- titioners to meet and discuss the wide-ranging scienti?c and technical issues related to the design of a new Internet. The sentiment shared in Vienna was that we are at the beginning of something very exciting and challenging and that FIS 2008 has played a role in forming a community to address this. With overa billionusers,today’s Internet is arguablythe most successful- man artifact ever created. The Internet’s physical infrastructure, software, and content now play an integralpart in the lives of everyoneon the planet, whether they interact with it directly or not. Now nearing its ?fth decade, the Int- net has shown remarkable resilience and ?exibility in the face of ever-increasing numbers of users, data volume, and changing usage patterns, but faces gr- ing challenges in meetings the needs of our knowledge society. Globally, many major initiatives are underway to address the need for more scienti?c research, physical infrastructure investment, better education, and better utilization of the Internet. Japan, the USA and Europe are investing heavily in this area. The EU is shaping around the idea of the Future Internet its research programmes for the Seventh Framework. EU commissioners, national government ministers, industry leadersand researchersmet in Bled, Slovenia during March 31–April2, 2008, to begin developing a vision of a future Internet that will meet Europe’s needs a decade from now, and beyond.

The Nature of Our Digital Universe

Abstract

A compelling question for the 21^st Century is “What is the nature of our digital universe?” In designing the Future Internet, we have a remarkable opportunity and need for a deeper understanding of this question. Based on the profound importance of our Future Digital World and on the role of the Future Internet in shaping it, this paper suggests holistic objectives for the design process and some thoughts on challenges and opportunities that the design process may face.

The Internet of Things in an Enterprise Context

Abstract

This paper puts the Internet of Things in a wider context: How it relates to the Future Internet overall, and where the business value lies so that it will become interesting for enterprises to invest in it. Real-World Awareness and Business Process Decomposition are the two major paradigms regarding future business value. The major application domains where the Internet of Things will play an important role and where there are concrete business opportunities are highlighted. But there are also many technical challenges that need to be addressed. These are listed and it is shown how they are tackled by existing research projects with industrial participation.

Security-By-Contract for the Future Internet

Abstract

With the advent of the next generation java servlet on the smartcard, the Future Internet will be composed by web servers and clients silently yet busily running on high end smart cards in our phones and our wallets. In this brave new world we can no longer accept the current security model where programs can be downloaded on our machines just because they are vaguely “trusted”. We want to know what they do in more precise details.

We claim that the Future Internet needs the notion of security-by-contract: In a nutshell, a contract describes the security relevant interactions that the smart internet application could have with the smart devices hosting them. Compliance with contracts should verified at development time, checked at depolyment time and contracts should be accepted by the platform before deployment and possibly their enforcement guaranteed, for instance by in-line monitoring.

In this paper we describe the challenges that must be met in order to develop a security-by-contract framework for the Future Internet and how security research can be changed by it.

e-Services in a Networked World: From Semantics to Pragmatics

Abstract

Today’s economy is a service economy, and an increasing number of services is electronic, i.e. can be ordered and provisioned online. Examples include Internet access, email and Voice over IP. Typically, e-services are offered as bundles consisting of more elementary services, offered by different suppliers, forming a network. This allows for best-of-breed solutions, in which the customer selects the best services from different suppliers to satisfy his need, and in which the supplier can focus on his core-competences. The research question is then how to compose such a multi-supplier service bundle. In this paper, we argue that first understanding of the context of the service is important. We propose a framework of ontologies, called e ³ family, which can be used to reason about the contextual socio-economical aspects of e-services. This framework can be used to elicit customer’s need, to compose service bundles satisfying such a need, and to reason about profitability of the found service provisioning network. We illustrate e ³ family by presenting two of its core-ontologies: e ³ value and e ³ service.

Hierarchical Modelling and an Approximate Analysis of Parallel Queues Models to the NGN SCEs

Abstract

The new-emerging inventive technologies that bring together the richness of IT applications with the superiority and intelligence of next-generation networks bring also about a dramatic jump in services value for all types of enterprises and carriers. It is seen by fundamental changes in the way applications and services are designed, developed, delivered, and used. With this new age comes a set of demanding technical challenges along with significant opportunities for technology innovation. Thus, we address here these challenges by evaluating NGNs service platform in terms of functionality, programmability, flexibility, openness, and inter-operability. Besides, in NGNs even a simple service has a complex structure. It consists from a lot of building blocks, which create hierarchical models with a lot of parallel subsystems. Thus, the NGN SCE has to be based on multiprocessing technology and parallel programming environments. And, our particular interest is in understanding and modeling the performance of parallel queuing models.

A First Step Towards Stream Reasoning

Abstract

While reasoners are year after year scaling up in the classical, time invariant domain of ontological knowledge, reasoning upon rapidly changing information has been neglected or forgotten. On the contrary, processing of data streams has been largely investigated and specialized Stream Database Management Systems exist. In this paper, by coupling reasoners with powerful, reactive, throughput-efficient stream management systems, we introduce the concept of Stream Reasoning. We expect future realization of such concept to have high impact on the future Internet because it enables reasoning in real time, at a throughput and with a reactivity not obtained in previous works.

Environmental Content Creation and Visualisation in the ‘Future Internet’

Abstract

This paper presents a model-based photo registration system for the creation and visualization of environmental content. We utilize freely available Digital Terrain Models of the planet, such as those provided by NASA, to generate a three-dimensional synthetic model around a viewer’s location. Using an array of image processing algorithms we then align photographs to this model. We will demonstrate the precision of the resulting system through the overlaying of Internet content (such as mountain names and GPS tracks), into geo-referenced photos. Additionally, we will show how a metric can be derived for photos that describes not only which mountains can be seen, but also how visible they are.

Having Services “YourWay!”: Towards User-Centric Composition of Mobile Services

Abstract

Mobile phones are becoming an essential tool in our life. They not only act as phones and media players, but more fundamentally they give us access to variety of services that we use in everyday life, including social networking, personal assistance, entertainment, travelling, and so on. Unfortunately, while the number of services increases, each service is narrowly directed to solve a specific user task with no attention to how the user may utilize these services in combination. At this stage, the combination of services and the integration of their information flows must be managed by the user on his own, in a handcrafted way.

To support the user in the composition of services and applications, we propose to organize the services around a small set of resources - time, location, social relations, money - which model the essential user assets handled by mobile services, and which guide the data integration and service composition.

In the paper, we discuss our current realization of such resource-based, user-centric service composition approach, detailing the underlying conceptual architecture and discussing the actual execution of the platform on a set of practical scenarios.

Beyond Usability: A New Frontier for User-Centered Design of “Future Internet” Services

Abstract

This paper proposes a new challenge for the Future Internet initiatives: the need of bridging the digital divide that, even in Europe, still hampers the access to the internet for a large part of the population. As a case study, we discuss the design of communication services for elderly people in northern Italy. The process was conducted by a multi-disciplinary team by involving a large group of stakeholders. The outcome was not just a set of simplified services but a new device offering sophisticated functionalities tailored to the actual needs of the targeted users and respectful of their personal meaningful practices. We argue that such a holistic approach that goes well beyond the objectives of usability and accessibility should become a common practice of approaching the design of new services for Future Internet.

Unlock Your Data: The Case of MyTag

Abstract

The business model of Web2.0 applications like FaceBook, Flickr, YouTube and their likes is based on an asymmetry: Users generate content, Web2.0 application providers own, (i), the access to user content, (ii), the user profiles and, (iii), user interaction data. We argue in this paper that such asymmetry disadvantages the users and prevents innovative applications. We demonstrate an application, MyTag, that is based on a layer for cross-application user profiling and personalization and that exploits web service access to user data. Presenting this application, we conclude that such applications offer additional value to users and usage of such applications on content generated by the users should not be at the disposal of the application provider, but should be a part of users’ rights.

A Framework for Selecting Trusted Semantic Web Services

Abstract

Trusted semantic Web services might play a key role in the Future Internet. In this paper, we describe WSTO our comprehensive trust based framework supporting the selection and invocation of semantic Web services. Our framework combines the Web Services Modelling Ontology (WSMO) with a classification framework developed in the IBROW project. Our approach is generic enough to be able to account for a wide variety of trust models including those based on security, policy and end-user recommendations. Expanding on earlier work within this paper, we describe the model in detail.

Future Internet Collaboration Workflow

Abstract

The Future Internet predicts more and more networked devices on the Internet. These devices interact, exchange knowledge, and cooperate in a dynamic environment, changing their states. Each state change may be signified by an event. In scenarios, where a number of devices collaborate on a common goal, it is a challenge to capture relevant complex changes, and abstract them in particular collaboration situations. Further on, it is even more challenging to put those changes in a relevant context, and to reason about collaboration situations before adequately reacting on events (changes). We present a novel event-driven reactivity model for Future Internet collaborations. We implement a flexible collaborative workflow in a declarative way, solving before mentioned challenges. Particularly, Concurrent Transaction Logic is used for specification, reasoning, and execution of ad-hoc collaborative workflows.

Towards an Ontological Foundation for Services Science

Abstract

Most of the efforts conducted on services nowadays are focusing on aspects related to data and control flow, often disregarding the main goal of the future Internet of services, namely to allow the smooth interaction of people and computers with services in the actual world. Our main claim is that it is crucial, to achieve such goal, to build a global service framework able to account for complex processes involving people and computers, which however have always people at their ends. That’s why in this paper we mostly emphasize the role of social and business-oriented services, whose consideration is needed to evaluate the global quality of e-services in relation to their ultimate social benefits, taking the overall impact on the organizational structure into account. Along these lines, the contribution of this proposal is a first concrete step towards a unified, rigorous and principled ontology centred on the notion of service availability, which results in useful distinctions betweenservice, service content, service delivery andservice process. Services are modelled by means of a layered set of interrelated events, with their own participants as well as temporal and spatial locations.

Challenges and Opportunities for More Meaningful and Sustainable Internet Systems

Abstract

Despite its technological success story, the Internet is facing a rampant growth of isolated ontologies and a massive dump of unstructured legacy data. Therefore, architecting the next generation of the Internet will require a paradigm shift that goes beyond technological excellence. This is the main hypothesis we take and defend in this paper. Main drivers behind the dynamics of this future Web 3.0 are the massive and meaningful reconciliation of disparate data sources and service discovery, and the pervasiveness of these processes in daily life and work of on-line communities. Paving our way to more meaningful and sustainable internet systems, we devise a three-dimensional problem space from which we draw challenges and methodological opportunities. Next, based on this, we propose a DNS of Information. Finally, we substantiate our proposal with related research projects, practices, and initiatives that act as main catalysts or adopters.
