Linking the communication and the information technology infrastructures forms the new Machine-to-machine (M2M) communication trend. We aim to exploit available standard protocols to support smart cities applications. In this paper, we report the work of implementing and evaluating the performance of using request/response protocols for M2M communications.(More)
In some use cases, a persistent end-to-end connection between a given data source and a destination may never be present. Consequently, traditional routing protocols cannot be directly applied for delivering data. One example are Wireless Sensor Networks (WSN), due to the limited capabilities of the connected nodes and the lack of a reliable connection(More)
The current trend of running software components on top of virtual machines in cloud platforms is gaining more momentum as it reduces the deployment time and operational costs in comparison to running them on dedicated hardware. By providing elasticity through orchestration, this approach brings even more value taking advantage of the resources on peak(More)
With a large majority of the world's population moving towards urban environments in the foreseeable future, the notion of Smart City is emerging globally as an important research topic. The population movement will affect the consumption rate of natural resources i.e. water, soil, and plants. Therefore, innovative management and monitoring systems are(More)
IoT is an evolving domain in which hardware and software components are modelling, sensing or influencing the properties of the physical world. In order to reach the full potential of an IoT service, security and flexibility are key requirements. For multiple service areas, such as supply chains or after-market services, access control and secure dispatch(More)
Smart Cities applications and infrastructures are actively being developed and rolled out. However, maintenance complexity is significant, often limiting deployments to small regions or small cities. To support gradual or spontaneous infrastructure scaling at region or national levels, infrastructure management that monitors end device connectivity and(More)
With the upcoming network function virtualization (NFV), aiming at deployment of core network functionality on top of cloud infrastructures, there is a stringent need for developing an appropriate evaluation process and the afferent automatic testing solutions. Before NFV, only black-box testing was needed, due to the physical isolation of the components in(More)
Cities increasingly face challenges related to pollution, efficient use of resources (e.g. water, energy) and ensuring a good quality of life for its citizens. Solutions built on existing and emerging technologies such as Cloud computing, Internet of Things, Machine-to-Machine and data analytics can improve on or create services able to address these(More)
