    Building a general architecture for the Internet of Things (IoT) is a very complex task, exacerbated by the extremely large variety of devices, link layer technologies, and services that may be involved in such a system. In this paper, we identify the main blocks of a generic IoT architecture, describing their features and requirements, and analyze the most common approaches proposed in the literature for each block. In particular, we compare three of the most important communication technologies for IoT purposes, i.e., REST, MQTT, and AMQP, and we also analyze three IoT platforms: openHAB, Sentilo, and Parse. The analysis will prove the importance of adopting an integrated approach that jointly addresses several issues and is able to flexibly accommodate the requirements of the various elements of the system. We also discuss a use case which illustrates the design challenges and the choices to make when selecting which protocols and technologies to use

To access the final edited version see http://www.internationaljpp.com/cgi-bin/go.pl/library/article.cgi?uid=100396;article=IPP_3_3_61_63Since the start of industrialisation in the beginning of the previous century, processes, and technology have evolved drastically. Technology that had been developed for a specific application was found to open new horizons in other domains. A good example is the use of sonar technology on military submarines which eventually found medical applications in medical imaging (Oakley, 1986). The paramedic profession is still considered to be a relatively young profession, and although the clinical scope of practice of ambulance staff has widened there have been few noticeable and significant changes in the way Ambulance Services operate as public service providers. There is, however, great variation in the way pre-hospital emergency care provision is delivered and organised from country to country due for example to historical, cultural, financial, and geographical factors. Other industries are significantly more driven by profit, hence efficiency and reliability are aspects that have a direct and measurable financial impact and it acts as a driver for further developments.Peer reviewedSubmitted Versio

    MOBILESAT: Australia's own

    Get PDF
    Australia will be introducing a dedicated Mobile Satellite Communications System following the launch of the AUSSAT-B satellites late in 1991. The Mobile Satellite System, MOBILESAT, will provide circuit switched voice/data services and packet-switched data services for land, aeronautical and maritime users. Here, an overview is given of the development program being undertaken within Australia to enable a fully commercial service to be introduced in 1992
