Un sistema di controllo accessi basato su tecnologie wearable

Negli ultimi anni il mondo ha assistito ad un'espansione esponenziale del mercato mobile, un settore che ha rivoluzionato le nostre vite e le nostre abitudini. Parallelamente, sono entrati in commercio i primi dispositivi commerciali dell'era dell'Internet delle Cose (Internet-of-Things), un paradigma secondo il quale oggetti utilizzati quotidianamente possono dialogare tra loro mediante Internet al fine di migliorare la vita personale e i processi produttivi aziendali. Un'applicazione pratica di Internet-of-Things è costituita dai dispositivi indossabili (wearable) capaci per mezzo di sensori di raccogliere dati sanitari, ambientali e fisici attorno a noi. I dispositivi indossabili attualmente in commercio permettono di collegarsi tramite protocolli e standard come WiFi e Bluetooth ad altri dispositivi, siano essi indossabili, smartphone o computer. Da questo concetto nasce l’idea di far comunicare un indossabile con altri dispositivi utilizzati in un contesto aziendale. In questo documento verrà preso in considerazione un tassello fondamentale nella gestione delle risorse umane e della sicurezza: il controllo degli accessi in un edificio e lo sblocco di un varco, sia esso un tornello, una porta o una serranda. Verrà quindi analizzato e progettato un sistema che possa effettuare le operazioni di timbratura e di apertura di varchi dall'orologio Apple Watch e da iPhone collegandosi ad un terminale dedicato.

INSPECTOR-PI: Progettazione e Sviluppo di un Sistema Mobile per il Controllo e il Monitoraggio basato su Tecnologie Embedded e Internet of Things

La nostra sfida è stata sviluppare un dispositivo che potesse riunire differenti funzionalità, dalla telepresenza alla visione dei dati on demand, e fosse in grado di portare innovazione nel panorama attuale. Abbiamo quindi deciso di creare un device che potesse svolgere attività d’ispezione e monitoraggio, concentrandoci nel corso dell’implementazione su alcuni possibili campi di utilizzo. Il sistema che abbiamo realizzato è open-source, modulare e dinamico, in grado di rispondere a esigenze diverse e facilmente riadattabile. Il prototipo progettato è in grado di comunicare con uno smartphone, grazie al quale viene guidato dall’utente primario, e di trasmettere in rete i dati rilevati dai diversi sensori integrati. Le informazioni generate sono gestibili attraverso una piattaforma online: il device utilizza il Cloud per storicizzare i dati, rendendoli potenzialmente accessibili a chiunque. Per la configurazione hardware abbiamo usato la kit-board Pi2Go e la piattaforma Raspberry Pi, alle quali abbiamo unito una videocamera e alcuni sensori di prossimità, temperatura e umidità e distanza. È nato così il prototipo InspectorPi, un veicolo telecomandato tramite dispositivo mobile in grado di esplorare ambienti ostili in cui vi sono difficoltà fisiche o ambientali alle quali sovvenire.

An Internet of Things approach for managing smart services provided by wearable devices.

The Internet of Things (IoT) is growing at a fast pace with new devices getting connected all the time. A new emerging group of these devices are the wearable devices, and Wireless Sensor Networks are a good way to integrate them in the IoT concept and bring new experiences to the daily life activities. In this paper we present an everyday life application involving a WSN as the base of a novel context-awareness sports scenario where physiological parameters are measured and sent to the WSN by wearable devices. Applications with several hardware components introduce the problem of heterogeneity in the network. In order to integrate different hardware platforms and to introduce a service-oriented semantic middleware solution into a single application, we propose the use of an Enterprise Service Bus (ESB) as a bridge for guaranteeing interoperability and integration of the different environments, thus introducing a semantic added value needed in the world of IoT-based systems. This approach places all the data acquired (e.g., via Internet data access) at application developers disposal, opening the system to new user applications. The user can then access the data through a wide variety of devices (smartphones, tablets, computers) and Operating Systems (Android, iOS, Windows, Linux, etc.).

Routex: un Router Multitecnologia per Internet of Things

L'Internet of Things (IoT) è oggetto di grande interesse per la ricerca e per l'industria. Le numerose tecnologie che sono state sviluppate rendono possibile la creazione di nuovi e utili servizi, ma introducono problemi legati alla reciproca incompatibilità. Nell'elaborato si analizza nel dettaglio questa situazione e si descrive l'implementazione di un sistema che ha come obiettivo la realizzazione di una rete composta da dispositivi che fanno uso di tecnologie differenti. Il progetto usa un Raspberry Pi come router, il cui scopo è quello di gestire le differenze fra gli standard di comunicazione utilizzati. Le tecnologie wireless supportate sono: WiFi, Bluetooth, ZigBee, nRF24L01 e moduli radio 433MHz. Sulla rete cosi formata è inoltre possibile lo sviluppo di applicazioni IoT, grazie alle logiche di funzionamento messe a disposizione dal sistema.

The Internet of Things : new digital capital in the hands of customers

The Internet of Things facilitates the identification, digitization, and control of physical objects. However, it is the availability of cost effective sensors, mobile smart devices, scalable cloud infrastructure, and advanced analytics that have consumerized the Internet of Things. The accessibility of digital representations of things has transformative potential and provides entire new affordances for organizations and their ecosystems across most industries.

Architectural Solutions for Mobile RFID Services on Internet of Things

Mobile RFID services for the Internet of Things can be created by using RFID as an enabling technology in mobile devices. Humans, devices, and things are the content providers and users of these services. Mobile RFID services can be either provided on mobile devices as stand-alone services or combined with end-to-end systems. When different service solution scenarios are considered, there are more than one possible architectural solution in the network, mobile, and back-end server areas. Combining the solutions wisely by applying the software architecture and engineering principles, a combined solution can be formulated for certain application specific use cases. This thesis illustrates these ideas. It also shows how generally the solutions can be used in real world use case scenarios. A case study is used to add further evidence.

Probabilistic Prediction based Scheduling for Delay Sensitive Traffic in Internet of Things

This paper proposes a probabilistic prediction based approach for providing Quality of Service (QoS) to delay sensitive traffic for Internet of Things (IoT). A joint packet scheduling and dynamic bandwidth allocation scheme is proposed to provide service differentiation and preferential treatment to delay sensitive traffic. The scheduler focuses on reducing the waiting time of high priority delay sensitive services in the queue and simultaneously keeping the waiting time of other services within tolerable limits. The scheme uses the difference in probability of average queue length of high priority packets at previous cycle and current cycle to determine the probability of average weight required in the current cycle. This offers optimized bandwidth allocation to all the services by avoiding distribution of excess resources for high priority services and yet guaranteeing the services for it. The performance of the algorithm is investigated using MPEG-4 traffic traces under different system loading. The results show the improved performance with respect to waiting time for scheduling high priority packets and simultaneously keeping tolerable limits for waiting time and packet loss for other services.

Integrated billing mechanisms in the Internet of Things to support information sharing and enable new business opportunities

The Internet of Things (IOT) concept and enabling technologies such as RFID offer the prospect of linking the real world of physical objects with the virtual world of information technology to improve visibility and traceability information within supply chains and across the entire lifecycles of products, as well as enabling more intuitive interactions and greater automation possibilities. There is a huge potential for savings through process optimization and profit generation within the IOT, but the sharing of financial benefits across companies remains an unsolved issue. Existing approaches towards sharing of costs and benefits have failed to scale so far. The integration of payment solutions into the IOT architecture could solve this problem. We have reviewed different possible levels of integration. Multiple payment solutions have been researched. Finally we have developed a model that meets the requirements of the IOT in relation to openness and scalability. It supports both hardware-centric and software-centric approaches to integration of payment solutions with the IOT. Different requirements concerning payment solutions within the IOT have been defined and considered in the proposed model. Possible solution providers include telcos, e-payment service providers and new players such as banks and standardization bodies. The proposed model of integrating the Internet of Things with payment solutions will lower the barrier to invoicing for the more granular visibility information generated using the IOT. Thus, it has the potential to enable recovery of the necessary investments in IOT infrastructure and accelerate adoption of the IOT, especially for projects that are only viable when multiple benefits throughout the supply chain need to be accumulated in order to achieve a Return on Investment (ROI). In a long-term perspective, it may enable IT-departments to become profit centres instead of cost centres. © 2010 - IOS Press and the authors. All rights reserved.

Dialogical strategies for orchestrating strategic innovation networks: the case of the Internet of Things

Strategic innovation has been shown to provide significant value for organisations whilst at the same time challenging traditional ways of thinking and working. There is less known, however, as to how organisations collaborate in innovation networks to achieve strategic innovation. In this paper we explore how innovation networks are orchestrated in developing a strategic innovation initiative around the Internet of Things. We show how a hub actor brings together a diverse group of actors to initially create and subsequently orchestrate the strategic innovation network through the employ of three dialogical strategies, namely persuasive projection, reflective development, and definitional control. Further, we illuminate how different types of legitimacy are established through these various dialogical strategies in orchestrating strategic innovation networks.

Internet of Things. A proposed secured network topology

The myriad of technologies and protocols working at different layers pose significant security challenges in the upcoming Internet of Things (IoT) paradigm. Security features and needs vary from application to application and it is layer specific. In addition, security has to consider the constraints imposed by energy limited sensor nodes and consider the specific target application in order to provide security at different layers. This paper analyses current standardization efforts and protocols. It proposes a generic secured network topology for IoT and describes the relevant security challenges. Some exploitation examples are also provided.
