An internet of social things

The Internet of Things is a vision for a world of interconnected smart devices. We present an alternative vision based on a review of literature that emphasizes the importance and role of objects in social relations. We situate this work in relation to a conceptual understanding of objects and sociality, and note some methodological implications of a more object-centred sociality that may suggest design opportunities alongside the emerging Internet of Things.

The internet of playful things

This one-day workshop brings together researchers and practitioners to share knowledge and practices on how people can connect and interact with the Internet of Things in a playful way. Open to participants with a diverse range of interests and expertise, and by exploring novel ways to playfully connect people through their everyday objects and activities, the workshop will facilitate discussion across a range of HCI discipline areas. The outcomes from the workshop will include an archive of participants' initial position papers along with the materials created during the workshop. The result will be a road map to support the development of a Model of Playful Connectedness, focusing on how best to design and make playful networks of things, identifying the challenges that need to be addressed in order to do so.

A decentralized batch-based group key management potocol for mobile Internet of Thngs (DBGK).

It is anticipated that constrained devices in the Internet of Things (IoT) will often operate in groups to achieve collective monitoring or management tasks. For sensitive and mission-critical sensing tasks, securing multicast applications is therefore highly desirable. To secure group communications, several group key management protocols have been introduced. However, the majority of the proposed solutions are not adapted to the IoT and its strong processing, storage, and energy constraints. In this context, we introduce a novel decentralized and batch-based group key management protocol to secure multicast communications. Our protocol is simple and it reduces the rekeying overhead triggered by membership changes in dynamic and mobile groups and guarantees both backward and forward secrecy. To assess our protocol, we conduct a detailed analysis with respect to its communcation and storage costs. This analysis is validated through simulation to highlight energy gains. The obtained results show that our protocol outperforms its peers with respect to keying overhead and the mobility of members.

WAIS seminar: Research Discussion: Lab of Things? What Things?

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.

How the web of things challenges requirements engineering

As a subset of the Internet of Things (IoT), the Web of Things (WoT) shares many characteristics with wireless sensor and actuator networks (WSANs) and ubiquitous computing systems (Ubicomp). Yet to a far greater degree than the IoT, WSANs or Ubicomp, the WoT will integrate physical and information objects, necessitating a means to model and reason about a range of context types that have hitherto received little or no attention from the RE community. RE practice is only now developing the means to support WSANs and Ubicomp system development, including faltering first steps in the representation of context. We argue that these techniques will need to be developed further, with a particular focus on rich context types, if RE is to support WoT application development. © 2012 Springer-Verlag.

Detección de rutinas : internet of people. Prueba de concepto

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.

Progetto e valutazione di una piattaforma sperimentale di Internet of Energy per veicoli elettrici

This dissertation deals with the development of a project concerning a demonstration in the scope of the Supply Chain 6 of the Internet of Energy (IoE) project: the Remote Monitoring Emulator, which bears my personal contribution in several sections. IoE is a project of international relevance, that means to establish an interoperability standard as regards the electric power production and utilization infrastructure, using Smart Space platforms. The future perspectives of IoE have to do with a platform for electrical power trade-of, the Smart Grid, whose energy is produced by decentralized renewable sources and whose services are exploited primarily according to the Internet of Things philosophy. The main consumers of this kind of smart technology will be Smart Houses (that is to say, buildings controlled by an autonomous system for electrical energy management that is interoperable with the Smart Grid) and Electric Mobility, that is a smart and automated management regarding movement and, overall, recharging of electrical vehicles. It is precisely in the latter case study that the project Remote Monitoring Emulator takes place. It consists in the development of a simulated platform for the management of an electrical vehicle recharging in a city. My personal contribution to this project lies in development and modeling of the simulation platform, of its counterpart in a mobile application and implementation of a city service prototype. This platform shall, ultimately, make up a demonstrator system exploiting the same device which a real user, inside his vehicle, would use. The main requirements that this platform shall satisfy will be interoperability, expandability and relevance to standards, as it needs to communicate with other development groups and to effectively respond to internal changes that can affect IoE.

Estudio de arquitecturas software para servicios de Internet de las Cosas

A medida que la sociedad avanza, la cantidad de datos almacenados en sistemas de información y procesados por las aplicaciones y servidores software se eleva exponencialmente. Además, las nuevas tecnologías han confiado su desarrollo en la red internacionalmente conectada: Internet. En consecuencia, se han aprovechado las conexiones máquina a máquina (M2M) mediante Internet y se ha desarrollado el concepto de "Internet de las Cosas", red de dispositivos y terminales donde cualquier objeto cotidiano puede establecer conexiones con otros objetos o con un teléfono inteligente mediante los servicios desplegados en dicha red. Sin embargo, estos nuevos datos y eventos se deben procesar en tiempo real y de forma eficaz, para reaccionar ante cualquier situación. Así, las arquitecturas orientadas a eventos solventan la comprensión del intercambio de mensajes en tiempo real. De esta forma, una EDA (Event-Driven Architecture) brinda la posibilidad de implementar una arquitectura software con una definición exhaustiva de los mensajes, notificándole al usuario los hechos que han ocurrido a su alrededor y las acciones tomadas al respecto. Este Trabajo Final de Grado se centra en el estudio de las arquitecturas orientadas a eventos, contrastándolas con el resto de los principales patrones arquitectónicos. Esta comparación se ha efectuado atendiendo a los requisitos no funcionales de cada uno, como, por ejemplo, la seguridad frente a amenazas externas. Asimismo, el objetivo principal es el estudio de las arquitecturas EDA (Event-Driven Architecture) y su relación con la red de Internet de las Cosas, que permite a cualquier dispositivo acceder a los servicios desplegados en esa red mediante Internet. El objeto del TFG es observar y verificar las ventajas de esta arquitectura, debido a su carácter de tipo inmediato, mediante el envío y recepción de mensajes en tiempo real y de forma asíncrona. También se ha realizado un estudio del estado del arte de estos patrones de arquitectura software, así como de la red de IoT (Internet of Things) y sus servicios. Por otro lado, junto con este TFG se ha desarrollado una simulación de una EDA completa, con todos sus elementos: productores, consumidores y procesador de eventos complejo, además de la visualización de los datos. Para ensalzar los servicios prestados por la red de IoT y su relación con una arquitectura EDA, se ha implementado una simulación de un servicio personalizado de Tele-asistencia. Esta prueba de concepto ha ayudado a reforzar el aprendizaje y entender con más precisión todo el conocimiento adquirido mediante el estudio teórico de una EDA. Se ha implementado en el lenguaje de programación Java, mediante las soluciones de código abierto RabbitMQ y Esper, ayudando a su unión el estándar AMQP, para completar correctamente la transferencia.

Context modelling for natural Human Computer Interaction applications in e-health

The conception of IoT (Internet of Things) is accepted as the future tendency of Internet among academia and industry. It will enable people and things to be connected at anytime and anyplace, with anything and anyone. IoT has been proposed to be applied into many areas such as Healthcare, Transportation，Logistics, and Smart environment etc. However, this thesis emphasizes on the home healthcare area as it is the potential healthcare model to solve many problems such as the limited medical resources, the increasing demands for healthcare from elderly and chronic patients which the traditional model is not capable of. A remarkable change in IoT in semantic oriented vision is that vast sensors or devices are involved which could generate enormous data. Methods to manage the data including acquiring, interpreting, processing and storing data need to be implemented. Apart from this, other abilities that IoT is not capable of are concluded, namely, interoperation, context awareness and security & privacy. Context awareness is an emerging technology to manage and take advantage of context to enable any type of system to provide personalized services. The aim of this thesis is to explore ways to facilitate context awareness in IoT. In order to realize this objective, a preliminary research is carried out in this thesis. The most basic premise to realize context awareness is to collect, model, understand, reason and make use of context. A complete literature review for the existing context modelling and context reasoning techniques is conducted. The conclusion is that the ontology-based context modelling and ontology-based context reasoning are the most promising and efficient techniques to manage context. In order to fuse ontology into IoT, a specific ontology-based context awareness framework is proposed for IoT applications. In general, the framework is composed of eight components which are hardware, UI (User Interface), Context modelling, Context fusion, Context reasoning, Context repository, Security unit and Context dissemination. Moreover, on the basis of TOVE (Toronto Virtual Enterprise), a formal ontology developing methodology is proposed and illustrated which consists of four stages: Specification & Conceptualization, Competency Formulation, Implementation and Validation & Documentation. In addition, a home healthcare scenario is elaborated by listing its well-defined functionalities. Aiming at representing this specific scenario, the proposed ontology developing methodology is applied and the ontology-based model is developed in a free and open-source ontology editor called Protégé. Finally, the accuracy and completeness of the proposed ontology are validated to show that this proposed ontology is able to accurately represent the scenario of interest.

Inteligencia ambiental en el Internet de las cosas

En la actualidad, existe un concepto que está cobrando especial relevancia, el cual es conocido como IoT (Internet of Things, Internet de las Cosas) [1]. En el IoT [2] se define la interconexión digital de objetos cotidianos con internet, esto significa que no sólo “los humanos” tenemos la capacidad de conectarnos a internet, sino que caminamos hacia una nueva era donde prácticamente cualquier cosa podría ser conectada a internet, desde un reloj (smartwatch), como tenemos en la actualidad, hasta una nevera, una persiana, una sartén, etc. En este proyecto se ha querido aplicar ciertas fases del IoT, para convertir una información ambiental poco sesgada, proporcionada por una pequeña estación meteorológica, en un valor adicional a la hora de tomar decisiones basadas en las variables ambientales, para determinar, según un proceso de aprendizaje automático, la sensación que una persona percibe en relación al tiempo meteorológico en un determinado momento. Para ello utilizamos una serie de sensores que se encargan de darnos la información ambiental necesaria (como la temperatura, humedad y presión atmosférica) una fuente de procesamiento como puede ser un micro-controlador, para después poder manejarla y procesarla en la nube, de forma remota, adquiriendo así el valor añadido que se espera en el IoT. Además, en este proyecto se aplican técnicas de Inteligencia Artificial para ayudar al usuario en esa toma de decisiones, mediante un proceso de entrenamiento previo, que permite obtener información relevante para aplicarla posteriormente en el contexto meteorológico mencionado. Para manejar todos estos conceptos y elementos, se hace uso de servicios Web, bases de datos, procesamiento y aprendizaje automático, integrando todos los servicios en una misma plataforma que facilite la comunicación de todos los elementos involucrados.

Un enfoque tolerante a interrupciones para la seguridad de la Internet de las cosas

La Internet de las cosas (IoT, Internet of Things) es un paradigma emergente que pretende la interconexión de cualquier objeto susceptible de contar con una parte de electrónica, favorecido por la miniaturización de los componentes. El estado de desarrollo de la IoT hace que no haya ninguna propuesta firme para garantizar la seguridad y la comunicación extremo a extremo. En este artículo presentamos un trabajo en progreso hacia una aproximación tolerante a retrasos (DTN, Delay and Disruption Tolerant Networks) para la comunicación en el paradigma de la IoT y planteamos la adaptación de los mecanismo de seguridad existentes en DTN a la IoT.

Sensor IoT para monitorización de consumo de energía en continua

Hoy en día la mayor parte de los sensores de energía IoT (Internet of Things) están orientados a la medida de corriente alterna (AC). No son aptos para monitorizar equipos que no estén conectados a la red eléctrica (baterías, paneles fotovoltaicos, etc.) o que formen parte de otros equipos más grandes y que estén situados detrás del transformador (ej. aceleradores de cómputo en supercomputadores). El presente trabajo tiene como objetivo principal construir un sistema, con una instalación sencilla y reducida, que permita la monitorización de consumo de dispositivos conectados a corriente continua. Toda la información recogida será mostrada a través de una interfaz web, que nos permitirá observar los cambios en el consumo en tiempo real con un intervalo de actualización especificado por el usuario. Además el sistema será robusto, con bajo coste de implementación y permitirá una alta escalabilidad, ya que el objetivo del proyecto es que sea escalable a nivel de centro de datos o institución.

RFID ownership transfer protocol based on cloud

RFID and Cloud computing are widely used in the IoT (Internet of Things). However, there are few research works which combine RFID ownership transfer schemes with Cloud computing. Subsequently, this paper points out the weaknesses in two protocols proposed by Xie et al. (2013) [3] and Doss et al. (2013) [9]. To solve the security issues of these protocols, we present a provably secure RFID ownership transfer protocol which achieves the security and privacy requirements for cloud-based applications. To be more specific, the communication channels among the tags, mobile readers and the cloud database are insecure. Besides, an encrypted hash table is used in the cloud database. Next, the presented protocol not only meets backward untraceability and the proposed strong forward untraceability, but also resists against replay attacks, tracing attacks, inner reader malicious impersonation attacks, tag impersonation attacks and desynchronization attacks. The comparisons of security and performance properties show that the proposed protocol has more security, higher efficiency and better scalability compared with other schemes.
