Con l’avvento dell’Industry 4.0, l’utilizzo dei dispositivi Internet of Things (IoT) è in continuo aumento. Le aziende stanno spingendo sempre più verso l’innovazione, andando ad introdurre nuovi metodi in grado di rinnovare sistemi IoT esistenti e crearne di nuovi, con prestazioni all’avanguardia. Un esempio di tecniche innovative emergenti è l’utilizzo dei Digital Twins (DT). Essi sono delle entità logiche in grado di simulare il reale comportamento di un dispositivo IoT fisico; possono essere utilizzati in vari scenari: monitoraggio di dati, rilevazione di anomalie, analisi What-If oppure per l’analisi predittiva. L’integrazione di tali tecnologie con nuovi paradigmi innovativi è in rapido sviluppo, uno tra questi è rappresentato dal Web of Things (WoT). Il Web of Thing è un termine utilizzato per descrivere un paradigma che permette ad oggetti del mondo reale di essere gestiti attraverso interfacce sul World Wide Web, rendendo accessibile la comunicazione tra più dispositivi con caratteristiche hardware e software differenti. Nonostante sia una tecnologia ancora in fase di sviluppo, il Web of Thing sta già iniziando ad essere utilizzato in molte aziende odierne. L’elaborato avrà come obiettivo quello di poter definire un framework capace di integrare un meccanismo di generazione automatica di Digital Twin su un contesto Web of Thing. Combinando tali tecnologie, si potrebbero sfruttare i vantaggi dell’interoperabilità del Web of Thing per poter generare un Digital Twin, indipendentemente dalle caratteristiche hardware e software degli oggetti da replicare.

Wednesday 19th March 2014 Speaker(s): Kirk Martinez, Dr Jonathon S Hare and Dr Enrico Costanza Organiser: Dr Tim Chown Time: 19/03/2014 11:00-11:50 Location: B32/3077 File size: 676 Mb Abstract The new WAIS seminar series features classic seminars, research discussions, tutorial-style presentations, and research debates. This seminar takes the form of a research discussion which will focus on the Internet of Things (IoT) research being undertaken in WAIS and other research groups in ECS. IoT is a significant emerging research area, with funding for research available from many channels including new H2020 programmes and the TSB. We have seen examples of IoT devices being built in WAIS and other ECS groups, e.g. in sensor networking, energy monitoring via Zigbee devices, and of course Erica the Rhino (a Big Thing!). The goal of the session is to briefly present such examples of existing Things in our lab with the intent of seeding discussion on open research questions, and therefore future work we could do towards new Things being deployed for experimentation in Building 32 or its environs. The session will discuss what 'things' we have, how they work, what new 'things' might we want to create and deploy, what components we might need to enable this, and how we might interact with these objects.

Abstract: There is a lot of hype around the Internet of Things along with talk about 100 billion devices within 10 years time. The promise of innovative new services and efficiency savings is fueling interest in a wide range of potential applications across many sectors including smart homes, healthcare, smart grids, smart cities, retail, and smart industry. However, the current reality is one of fragmentation and data silos. W3C is seeking to fix that by exposing IoT platforms through the Web with shared semantics and data formats as the basis for interoperability. This talk will address the abstractions needed to move from a Web of pages to a Web of things, and introduce the work that is being done on standards and on open source projects for a new breed of Web servers on microcontrollers to cloud based server farms. Speaker Biography -Dave Raggett : Dave has been involved at the heart of web standards since 1992, and part of the W3C Team since 1995. As well as working on standards, he likes to dabble with software, and more recently with IoT hardware. He has participated in a wide range of European research projects on behalf of W3C/ERCIM. He currently focuses on Web payments, and realising the potential for the Web of Things as an evolution from the Web of pages. Dave has a doctorate from the University of Oxford. He is a visiting professor at the University of the West of England, and lives in the UK in a small town near to Bath.

El principal objetivo de Internet of Things (IoT) es integrar las tecnologías informáticas en el quehacer cotidiano de las personas, facilitando su interacción con un entorno de dispositivos interconectados, pero el estado actual del arte hace que dicha interacción esté aún lejos de resultar trivial, precisando de continua intervención del usuario. Como alternativa a esta situación, iniciativas emergentes como la de Internet of People (IoP) pretenden integrar de forma más efectiva el IoT en la vida de las personas. En línea con este propósito, el modelo People as a Service (PeaaS) facilita estas tareas por medio del uso del teléfono móvil como interfaz del usuario con el IoT y haciendo uso del contexto del usuario del mismo. PeaaS permite elaborar un perfil sociológico del usuario, que puede ser explotado por el mismo y servido a terceros de forma segura y controlada. En este trabajo presentamos una aplicación móvil para la supervisión de personas afectadas de alzhéimer mediante el aprendizaje y monitorización de sus rutinas como prueba de concepto del modelo PeaaS, teniendo como resultado una funcionalidad que va mucho más allá de la ofrecida por otros productos similares en este campo, y una tecnología que es base para infinidad de aplicaciones que provoquen el avance hacia IoP.

Negli ultimi anni l’evoluzione tecnologica ha avuto un incremento esponenziale; ogni anno, numerose innovazioni, hanno portato notevoli cambiamenti sulla vita dei consumatori e sul modo in cui essi interagiscono. Al giorno d’oggi, la tecnologia ha raggiunto livelli tali da renderne necessario l’utilizzo per poter soddisfare vari tipi di bisogni. In questa situazione, lo sviluppo di Internet ha consentito di poter entrare in una nuova era, quella dell’Internet of Things (IoT). Questo nuovo modello sarebbe in grado di portare grossi benefici nella vita di tutte le persone, partendo dalle grandi aziende, fino ad arrivare ai singoli consumatori. L’idea di questo progetto di tesi è di posizionare un dispositivo, in grado di poter rilevare temperatura ed umidità dell’ambiente, nei locali universitari nei quali sono immagazzinati i libri, in modo tale da poter monitorare l’andamento termico degli spazi ed eventualmente effettuare delle operazioni di ripristino della temperatura e dell’umidità per evitare il danneggiamento e il deterioramento dei materiali. In questo documento di tesi andremo ad approfondire l’implementazione del dispositivo IoT in grado di rilevare i dati dell’ambiente. Nello specifico analizzeremo l’ambito applicativo di questo dispositivo, l’implementazione del sistema su una scheda Raspberry Pi 4, sfruttando anche un componente aggiuntivo contenente in sensori necessari al funzionamento del sistema, e vedremo nello specifico anche l’implementazione della pagina Web creata per la visualizzazione dei dati. Negli ultimi anni abbiamo vissuto una grande crisi a livello sanitario e oggi stiamo passando un periodo di difficoltà economica dovuta all’aumento del costo di alcune materie prime quali elettricità e gas. I futuri sviluppi su questo progetto potrebbero portare a risolvere in piccolo alcuni di questi problemi.

As the complexity of embedded systems increases, multiple services have to compete for the limited resources of a single device. This situation is particularly critical for small embedded devices used in consumer electronics, telecommunication, industrial automation, or automotive systems. In fact, in order to satisfy a set of constraints related to weight, space, and energy consumption, these systems are typically built using microprocessors with lower processing power and limited resources. The CooperatES framework has recently been proposed to tackle these challenges, allowing resource constrained devices to collectively execute services with their neighbours in order to fulfil the complex Quality of Service (QoS) constraints imposed by users and applications. In order to demonstrate the framework's concepts, a prototype is being implemented in the Android platform. This paper discusses key challenges that must be addressed and possible directions to incorporate the desired real-time behaviour in Android.

Our day-to-day life is dependent on several embedded devices, and in the near future, many more objects will have computation and communication capabilities enabling an Internet of Things. Correspondingly, with an increase in the interaction of these devices around us, developing novel applications is set to become challenging with current software infrastructures. In this paper, we argue that a new paradigm for operating systems needs to be conceptualized to provide aconducive base for application development on Cyber-physical systems. We demonstrate its need and importance using a few use-case scenarios and provide the design principles behind, and an architecture of a co-operating system or CoS that can serve as an example of this new paradigm.

This paper is concerned with the uniformization of a system of afine recurrence equations. This transformation is used in the design (or compilation) of highly parallel embedded systems (VLSI systolic arrays, signal processing filters, etc.). In this paper, we present and implement an automatic system to achieve uniformization of systems of afine recurrence equations. We unify the results from many earlier papers, develop some theoretical extensions, and then propose effective uniformization algorithms. Our results can be used in any high level synthesis tool based on polyhedral representation of nested loop computations.

How to create or integrate large Smart Spaces (considered as mash-ups of sensors and actuators) into the paradigm of ?Web of Things? has been the motivation of many recent works. A cutting-edge approach deals with developing and deploying web-enabled embedded devices with two major objectives: 1) to integrate sensor and actuator technologies into everyday objects, and 2) to allow a diversity of devices to plug to Internet. Currently, developers who want to use this Internet-oriented approach need have solid understanding about sensorial platforms and semantic technologies. In this paper we propose a Resource-Oriented and Ontology-Driven Development (ROOD) methodology, based on Model Driven Architecture (MDA), to facilitate to any developer the development and deployment of Smart Spaces. Early evaluations of the ROOD methodology have been successfully accomplished through a partial deployment of a Smart Hotel.

Food safety has always been a social issue that draws great public attention. With the rapid development of wireless communication technologies and intelligent devices, more and more Internet of Things (IoT) systems are applied in the food safety tracking field. However, connection between things and information system is usually established by pre-storing information of things into RFID Tag, which is inapplicable for on-field food safety detection. Therefore, considering pesticide residue is one of the severe threaten to food safety, a new portable, high-sensitivity, low-power, on-field organophosphorus (OP) compounds detection system is proposed in this thesis to realize the on-field food safety detection. The system is designed based on optical detection method by using a customized photo-detection sensor. A Micro Controller Unit (MCU) and a Bluetooth Low Energy (BLE) module are used to quantize and transmit detection result. An Android Application (APP) is also developed for the system to processing and display detection result as well as control the detection process. Besides, a quartzose sample container and black system box are also designed and made for the system demonstration. Several optimizations are made in wireless communication, circuit layout, Android APP and industrial design to realize the mobility, low power and intelligence.

The Internet of things (IoT) is still in its infancy and has attracted much interest in many industrial sectors including medical fields, logistics tracking, smart cities and automobiles. However, as a paradigm, it is susceptible to a range of significant intrusion threats. This paper presents a threat analysis of the IoT and uses an Artificial Neural Network (ANN) to combat these threats. A multi-level perceptron, a type of supervised ANN, is trained using internet packet traces, then is assessed on its ability to thwart Distributed Denial of Service (DDoS/DoS) attacks. This paper focuses on the classification of normal and threat patterns on an IoT Network. The ANN procedure is validated against a simulated IoT network. The experimental results demonstrate 99.4% accuracy and can successfully detect various DDoS/DoS attacks.
