Nowadays, the maturity of IoT applications, networking technologies and manufacturers of "things" have caused an explosion in the number of connected devices. There are several reports which calculate that the number of connected things will reach 50 billion in the near future. This paper focuses on the provision of wide area and efficient connectivity to the Internet of Things(IoT), akeyfactorinsuchanexplosion,...
Software-Defined Networking and Network Functions Virtualisation has brought a revolution within the telecom market landscape. Initial proof-of-concept prototypes for NFV-enabled solutions are being developed at the same time SDN models are identified as the futures solutions within the telecom realm. We provide in this article an overview of the SDN/NFV technologies over optical networks, as well...
Software-Defined Networking and Network Functions Virtualisation have iniatiated a new landscape within the telecom market landscape. Initial proof-of-concept prototypes for NFV-enabled solutions are being developed at the same time SDN models are identified as the futures solutions within the telecom realm. In this article, we provide a brief overview of the application and state-of-the-art of SDN...
Virtualisation of both IT and network resources is a well-known research topic in the Future Internet environment. Most of the work performed on virtualisation has been focused on virtual infrastructure planning or embedding, or on the realisation of the virtualisation itself. However, management of virtualised network environments has not been deeply included into the research studies. We present...
Future manufacturing systems will require to process large amounts of complex data due to a rising demand on visibility and vertical integration of factory floor devices with higher level systems. Systems contained in higher layers of the business model are rapidly moving towards a Service Oriented Architecture, inducing a tendency to push Web Technologies down to the factory floor level. Evidence...
In this paper we propose energy efficient design and operation of infrastructures incorporating integrated optical network and IT resources. For the first time we quantify significant energy savings of a complete solution jointly optimizing the allocation and provisioning of both network and IT resources. Our approach involves virtualization of the infrastructure resources and it is proposed and developed...
Coupling in software applications is often used as an indicator of external quality attributes such as fault-proneness. In fact, the correlation of coupling metrics and faults in object oriented programs has been widely studied. However, there is very limited knowledge about which coupling properties in aspect-oriented programming (AOP) are effective indicators of faults in modules. Existing coupling...
In this paper, we describe PREVIRNEC, a distributed system for cognitive telerehabilitation based on virtual environments. Our system allows personalized treatments by means of 2D and 3D exercises that can be built according to single patient's characteristics. Patients realize their exercises remotely. Depending on their obtained results, the system readjusts automatically the levels of difficulty...
An increasing number of users are surrounded by multiple computing devices such as PDAs and cell phones. There is some evidence that the use of mobile devices in health care settings might improve decision-making and reduce the numbers of medical errors. However, mobile devices are not commonly used in telemedicine and health care, and there is a lack of suitable functions and software applications...
The ability of understanding humanpsilas behavior is a required component for many applications. This understanding includes, among other tasks, automatically generating and maintaining models of human actions, goals and plans. This paper presents a system to infer the actions that people perform in order to accomplish activities of daily living starting from sensory inputs. Our approach is based...
The paper presents the implementation of a platform which allows the generation, annotation and retrieval of on-the-move multimedia tourist contents while on a tourist destination. The platform toggles the different stages of the processes involved on the cycle of life of the content: creation, indexation, storage and publication. The application has been implemented using the J2ME standard to take...
This paper describes a generic, scalable, and distributed framework for real-time video-analysis intended for research, prototyping and services deployment purposes. The architecture considers multiple cameras and is based on a server/client model. The information generated by each analysis module and the context information are made accessible to the whole system by using a database system. System...
