Recent activity in the field of Internet-of-Things experimentation has focused on the federation of discrete testbeds, thus placing less effort in the integration of other related technologies, such as smartphones; also, while it is gradually moving to more application-oriented paths, such as urban settings, it has not dealt in large with applications having social networking features. We argue here that current IoT infrastructure, testbeds and related software technologies should be used in such a context, capturing real-world human mobility and social networking interactions, for use in evaluating and fine-tuning realistic mobility models and designing human-centric applications. We discuss a system for producing traces for a new generation of human-centric applications, utilizing technologies such as Bluetooth and focusing on human interactions. We describe the architecture for this system and the respective implementation details presenting two distinct deployments; one in an office environment and another in an exhibition/conference event with 103 active participants combined, thus covering two popular scenarios for human centric applications. Our system provides online, almost real-time, feedback and statistics and its implementation allows for rapid and robust deployment, utilizing mainstream technologies and components.

In this article, a unified framework for multimodal search and retrieval is introduced. The framework is an outcome of the research that took place within the I-SEARCH European Project. The proposed system covers all aspects of a search and retrieval process, namely low-level descriptor extraction, indexing, query formulation, retrieval and visualisation of the search results. All I-SEARCH components advance the state of the art in the corresponding scientific fields. The I-SEARCH multimodal search engine is dynamically adapted to end-user’s devices, which can vary from a simple mobile phone to a high-performance PC.

Researchers from all over the world are engaged in the design of a new Internet, and Software-Defined Networking (SDN) is one of the results of this engagement. Net-Ontology uses a SDN approach to bring semantics to the intermediate network layers and make them capable of handling application requirements and adapt their behaviour over time as required. In this paper we present an experimental evaluation of Net-Ontology and a feature comparison against the traditional TCP/IP stack. This paper extends our earlier work towards a Future Internet, showing a viable approach to introduce semantics at network lower layers by contributing to bring richer and efficient services.

We show how the applications utilizing a Future Internet architecture can benefit from its features like quality of service (QoS) provisioning and resources reservation.We demonstrate, how proposed applications address content, context and user awareness basing on the underlying Next Generation Network (NGN) infrastructure and how it can be used to host service-based applications.

Innovation in smart city systems is based on the principle that devices, places and everyday things can each be enabled to serve people in a real-time and responsive manner. This chapter presents a novel approach to the design of smart city systems that takes into account not only technical installations in a future Internet of Things environment, but also the power of human storytelling in an always-on networked world. It is only when environments are both sensor-driven and socially-aware that a more holistic, and therefore more useful, urban narrative can emerge in the future Internet context. The present chapter proposes a new narrative-aware design framework and applies it to a hypothetical city scenario in order to highlight its main components and the benefits it may offer to a future Internet city’s actors.

Smart cities are emerging fast and they introduce new practices and services which highly impact policy making and planning, while they co-exist with urban facilities. It is now needed to understand the smart city’s contribution in the overall urban planning and vice versa, to recognize urban planning offerings to a smart city context. This chapter highlights and measures smart city and urban planning interrelation and identifies the meeting points among them. Urban planning dimensions are drawn from the European Regional Cohesion Policy and they are associated with smart city’s architecture layers.

Public Safety is nowadays a priority, cornerstone and major concern for governments, majors and policy makers in current (and future) smart cities. Notwithstanding the foregoing, large advances in ICT technologies are foretold to revolutionize our society and enhance our feeling of safety (and hopefully, wellbeing). This chapter presents an introduction to three of the most promising technological pillars considered to be spearheads in this transformation: Internet of things, understood as the data capillarity through billions of sensors, Intelligent Video Analytics and Data Mining Intelligence, the latter two enabling smarter contextual awareness and prediction of potential threats leading to proactive prevention of them. The associated horizontal economic implications of this evolution and its impact into the societal and economic fabric are also tackled. Part of the results and analysis produced in this chapter are the outcome of the work carried out in the FP7 EU project SafeCity, one of the eight Use Cases of the FI Programme.

Today organizations own resources and infrastructures (i.e. networking devices, gateways, wireless devices) that would like to either offer through the cloud model or to combine with resources of other infrastructures. Federation can be enabled by means of a resource broker that matches customer’s requested services and providers’ resources according to the agreed SLA. Users need ways to define complex deployments and request for resources without knowing the underlying infrastructure details. In this paper we present the Federation Scenario Toolkit (FSToolkit) that enables the definition of resource request scenarios, agnostic in term of providers. This work adopts Software Engineering practices considering the concepts of modeling and meta-modeling to define a resource broker and to specify scenarios by applying the Domain Specific Modeling (DSM) paradigm. FSToolkit is developed for experimentally driven research for validating through testing-scenarios new architectures and systems at scale and under realistic environments by enabling federation of resources.

The EC FP7/FIRE STREP project - - explores efficient approaches to compose virtualized e-Infrastructures towards a holistic Future Internet (FI) cloud service. Resources belonging to various levels, i.e. networking, storage and processing are in principle managed by separate yet inter-working providers. In this ecosystem NOVI aspires to develop and validate methods, information systems and algorithms that will provide users with isolated slices, baskets of resources and services drawn from federated infrastructures. Experimental research accomplished thus far concludes the first phase of NOVI, with early prototypes of semantic-aware advanced control & management plane components being deployed and tested. The NOVI testing environment is based on combining PlanetLab and FEDERICA, two dissimilar virtualized experimental infrastructures with attributes widely anticipated in a FI cloud. This federated testbed is stitched at the data plane via the NSwitch, a distributed virtual switch developed within NOVI.

Optical networking is the cornerstone of the Future Internet as it provides the physical infrastructure of the core backbone networks. Recent developments have enabled much better quality of service/experience for the end users, enabled through the much higher capacities that can be supported. Furthermore, optical networking developments facilitate the reduction of complexity of operations at the IP layer and therefore reduce the latency of the connections and the expenditures to deploy and operate the networks. New research directions in optical networking promise to further advance the capabilities of the Future Internet. In this book chapter, we highlight the latest activities of the optical networking community and in particular what has been the focus of EU funded research. The concepts of flexible and cognitive optical networks are introduced and their key expected benefits are highlighted. The overall framework envisioned for the future cognitive flexible optical networks are introduced and recent developments are presented.
