TL;DR: This demo presents the prototype of a scalable architecture for a large scale social Web of Things for smart objects and services, named Paraimpu, a Web-based platform which allows to add, use, share and inter-connect real HTTP-enabledSmart objects and "virtual" things like services on the Web and social networks.
Abstract: The Web of Things is a scenario where potentially billions of connected smart objects communicate using the Web protocols, HTTP in primis. A Web of Things envisioning and design has raised several research issues, from protocols adoption and communication models to architectural styles and social aspects facing. In this demo we present the prototype of a scalable architecture for a large scale social Web of Things for smart objects and services, named Paraimpu. It is a Web-based platform which allows to add, use, share and inter-connect real HTTP-enabled smart objects and "virtual" things like services on the Web and social networks. Paraimpu defines and uses few strong abstractions, in order to allow mash-ups of heterogeneous things introducing powerful rules for data adaptation. Adding and inter-connecting objects is supported through user friendly models and features.

TL;DR: This paper presents the vision about the anatomy of a scalable architecture for a large scale social Web of Things for smart objects and the solutions adopted, and a prototype is proposed and two experimented scenarios are described.
Abstract: The ongoing evolution of the Internet of Things toward the Web of Things, where Web-enabled smart objects connect and communicate using the protocols of the Web, has raised several research issues from protocols adoption and communication models to architectural styles. In this paper we present our vision about the anatomy of a scalable architecture for a large scale social Web of Things for smart objects and the solutions adopted. Main faced issues include a reasoned exploration of design choices in conjunction with the related state-of-art analysis, technologies, concepts and social aspects behind our proposed solution. Among them, a prototype is proposed and two experimented scenarios are described. Finally, this paper reports the conclusion, challenges and future works toward the evolution of our social Web of Things architecture and tool.

TL;DR: A Service-oriented Architecture (SOA) where things are Web Services using WSDL standard and logical connections between things are modeled as Web Services orchestrations using the WS-BPEL language is envisioned.
Abstract: The Web of Things is an emerging scenario in which objects are connected to Internet and can answer to HTTP queries. To date, new applications in this field are mainly produced by designers and engineers while we claim that with simple and effective composition rules and easy-to-use building blocks, even users could invent new applications unforeseen by technology experts. In this paper, we describe a solution for modeling, implementing and running simple connections of smart things based on the point-click-and-compose paradigm. We envision a Service-oriented Architecture (SOA) where things are Web Services using WSDL standard and logical connections between things are modeled as Web Services orchestrations using the WS-BPEL language.

TL;DR: Paraimpu, a prototype of a scalable platform able to collect, manage and share heterogeneous kinds of sensor data, is presented.
Abstract: The scientific and technological advances generate an exponentially growth of the number of sensors and the parallel decrease of their cost. The result is a huge number of heterogeneous sensor surrounding us. In this demo we present Paraimpu, a prototype of a scalable platform able to collect, manage and share heterogeneous kinds of sensor data.

TL;DR: A thorough analysis of the challenges and the enabling technologies in developing an IoT middleware that embraces the heterogeneity of IoT devices and also supports the essential ingredients of composition, adaptability, and security aspects of an IoT system is conducted.
Abstract: The Internet of Things (IoT) provides the ability for humans and computers to learn and interact from billions of things that include sensors, actuators, services, and other Internet-connected objects. The realization of IoT systems will enable seamless integration of the cyber world with our physical world and will fundamentally change and empower human interaction with the world. A key technology in the realization of IoT systems is middleware, which is usually described as a software system designed to be the intermediary between IoT devices and applications. In this paper, we first motivate the need for an IoT middleware via an IoT application designed for real-time prediction of blood alcohol content using smartwatch sensor data. This is then followed by a survey on the capabilities of the existing IoT middleware. We further conduct a thorough analysis of the challenges and the enabling technologies in developing an IoT middleware that embraces the heterogeneity of IoT devices and also supports the essential ingredients of composition, adaptability, and security aspects of an IoT system.

TL;DR: The evolutionary stages, i.e., generations, that have characterized the development of IoT are presented, along with the motivations of their triggering, and the role that IoT can play in addressing the main societal challenges and the set of features expected from the relevant solutions are analyzed.
Abstract: The high penetration rate of new technologies in all the activities of everyday life is fostering the belief that for any new societal challenge there is always an ICT solution able to successfully deal with it. Recently, the solution that is proposed almost anytime is the “Internet of Things” (IoT). This apparent panacea of the ICT world takes different aspects on and, actually, is identified with different (often very different) technological solutions. As a result, many think that IoT is just RFIDs, others think that it is sensor networks, and yet others that it is machine-to-machine communications. In the meanwhile, industrial players are taking advantage of the popularity of IoT to use it as a very trendy brand for technology solutions oriented to the consumer market. The scientific literature sometimes does not help much in clarifying, as it is rich in definitions of IoT often discordant between them. Objective of this paper is to present the evolutionary stages, i.e., generations, that have characterized the development of IoT, along with the motivations of their triggering. Besides, it analyzes the role that IoT can play in addressing the main societal challenges and the set of features expected from the relevant solutions. The final objective is to give a modern definition of the phenomenon, which de facto shows a strong pervasive nature, and, if not well understood in its theories, technologies, methodologies, and real potentials, then runs the risk of being regarded with suspicion and, thus, rejected by users.

TL;DR: This paper explores the novel paradigm for ubiquitous computing beyond IoT, denoted by Social Internet of Things (SIoT), and proposes a generic SIoT architecture and presents a discussion about enabling technologies, research challenges, and open issues.
Abstract: The cluster between Internet of Things (IoT) and social networks (SNs) enables the connection of people to the ubiquitous computing universe. In this framework, the information coming from the environment is provided by the IoT, and the SN brings the glue to allow human-to-device interactions. This paper explores the novel paradigm for ubiquitous computing beyond IoT, denoted by Social Internet of Things (SIoT). Although there have been early-stage studies in social-driven IoT, they merely use one or some properties of SIoT to improve a number of specific performance variables. Therefore, this paper first addresses a complete view on SIoT and key perspectives to envision the real ubiquitous computing. Thereafter, a literature review is presented along with the evolutionary history of IoT research from Intranet of Things to SIoT. Finally, this paper proposes a generic SIoT architecture and presents a discussion about enabling technologies, research challenges, and open issues.
