Experimental Evaluation of a SIP-Based Home Gateway with Multiple Wireless Interfaces for Domotics Systems

In modern houses, the presence of sensors and actuators is increasing, whilecommunication servicesandentertainment systemshad long since settled into everyday life. The utilization of wireless communication technologies, such as ZigBee, Wi-Fi, and Bluetooth, is attractive because of their short installation times and low costs. The research is moving towards the integration of the various home appliances and devices into a single domotics system, able to exploit the cooperation among the diverse subsystems and offer the end-user a single multiservice platform. In this scenario, the paper presents the experimental evaluation of a domotics framework centered on a SIP-based home gateway (SHG). While SIP is used to build a common control plane, the SHG is in charge of translating the user commands from and to the specific domotics languages. The analysis has been devoted to assess both the performance of the SHG software framework and the negative effects produced by the simultaneous interference among the three widespread wireless technologies

An Experimental Platform for large-scale research facing FI-IoT scenarios

Providing experimental facilities for the Internet of Things (IoT) world is of paramount importance to materialise the Future Internet (FI) vision. The level of maturity achieved at the networking level in Sensor and Actuator networks (SAN) justifies the increasing demand on the research community to shift IoT testbed facilities from the network to the service and information management areas. In this paper we present an Experimental Platform fulfilling these needs by: integrating heterogeneous SAN infrastructures in a homogeneous way; providing mechanisms to handle information, and facilitating the development of experimental services. It has already been used to deploy applications in three different field trials: smart metering, smart places and environmental monitoring and it will be one of the components over which the SmartSantander project, that targets a large-scale IoT experimental facility, will rely o

Smart Grid Communications: Overview of Research Challenges, Solutions, and Standardization Activities

Optimization of energy consumption in future intelligent energy networks (or Smart Grids) will be based on grid-integrated near-real-time communications between various grid elements in generation, transmission, distribution and loads. This paper discusses some of the challenges and opportunities of communications research in the areas of smart grid and smart metering. In particular, we focus on some of the key communications challenges for realizing interoperable and future-proof smart grid/metering networks, smart grid security and privacy, and how some of the existing networking technologies can be applied to energy management. Finally, we also discuss the coordinated standardization efforts in Europe to harmonize communications standards and protocols.Comment: To be published in IEEE Communications Surveys and Tutorial

Communication Architecture for Tracking and Interoperable Services at Hospitals: A Real Deployment Experience

Any new hospital communication architecture has to support existing services, but at the same time new added features should not affect normal tasks. This article deals with issues regarding old and new systems’ interoperability, as well as the effect the human factor has in a deployed architecture. It also presents valuable information, which is a product of a real scenario. Tracking services are also tested in order to monitor and administer several medical resources

Threats and perspective for the Internet of Things

Il paradigma di ubiquitous computing sta lentamente entrando nella vita di tutti i giorni, gli utenti sono sempre connessi e una nuova esigenza di monitoraggio e controllo sta nascendo. Dispositivi di comunicazione intelligenti, le reti domestiche multimediali e l’automazione industriale sono alcune coniugazioni possibili del paradigma di ubiquitous computing che sono ora disponibili per l’utente finale. La diffusione di questi sistemi è infatti destinata a crescere, spinta da entrambi i mondi accademico e industriale la quantità di lavoro di ricerca in questo campo è in aumento, e diverse aziende hanno messo le proprie soluzioni sul mercato. Nella visione di molti, l’utente sarebbe poi in grado di godere dei vantaggi di un sistema intelligente e impercettibile che si adatta all’ambiente ed ai suoi bisogni e unisce tutte le applicazioni e i servizi in un unico sistema integrato e facile da controllare. In questo lavoro vengono valutate alcune delle sfide architettoniche di questo nuovo modo di interagire tra l’utente e il suo ambiente circostante. Vengono mostrate la progettazione e la realizzazione di un SIP-based Home Gateway per il controllo remoto di Smart Objects in un ambiente domotico. È presentata anche un’architettura basata sul protocollo SIP per realizzare un sistema di domotica capace di interagire con dispositivi eterogenei e con varie interfacce utente, l’architettura si basa sull’uso del protocollo SIP come piano di controllo comune ed è centrata sul SIP Gateway Home. Per valutare le capacità del sistema descritto abbiamo effettuato anche una valutazione delle prestazioni, considerando i due problemi principali per questo tipo di dispositivi: scalabilita ad un elevato numero di richieste di servizio per secondo e l’interferenza/coesistenza di dispositivi appartenenti a diverse tecnologie/standard (ZigBee, Bluetooth, e Wi-Fi) presenti sullo stesso dispositivo. Sono stati valutati anche i problemi di sicurezza attraverso lo studio sperimentale di un Intrusion Detection System per attenuare tali problemi

VCare: A Personal Emergency Response System to Promote Safe and Independent Living Among Elders Staying by Themselves in Community or Residential Settings

‘Population aging’ is a growing concern for most of us living in the twenty first century, primarily because many of us in the next few years will have a senior person to care for - spending money towards their healthcare expenditures AND/OR having to balance a full-time job with the responsibility of care-giving, travelling from another city to be with this elderly citizen who might be our parent, grand-parent or even community elders. As informal care-givers, if somehow we were able to monitor the day-to-day activities of our elderly dependents, and be alerted when wrong happens to them that would be of great help and lower the care-giving burden considerably. Information and Communication Technology (ICT) can certainly help in such a scenario, with tools and techniques that ensure safe living for the individual we are caring for, and save us from a lot of worry by providing us with anytime access into their lives or activities, and as a result check their functional state. However, we should be mindful of the tactics that could be adopted by harm causers to steal data stored in these products and try to curb the associated service costs. In short, we are in need of robust, cost-effective, useful, and secure solutions to help elders in our society to ‘age gracefully’. This work is a little step taken towards that direction. ‘Population aging’ is a growing concern for most of us living in the twenty first century, primarily because many of us in the next few years will have a senior person to care for - spending money towards their healthcare expenditures AND/OR having to balance a full-time job with the responsibility of care-giving, travelling from another city to be with this elderly citizen who might be our parent, grand-parent or even community elders.
