Current trends towards the Future Internet are envisaging the conception of novel services endowed with context-aware and autonomic capabilities to improve end users’ quality of life. The Internet of Things paradigm is expected to contribute towards this ambitious vision by proposing models and mechanisms enabling the creation of networks of “smart things”(More)
Several mobile guides exist providing tourists with location-based content delivery. This paper presents a novel mobile application, named InfoTour, aiming at enriching tourists’ experiences by supporting social interactions among tourists and by enabling seamless interaction with third-party service and data providers. The proposed system is based(More)
Complex Event Processing (CEP) is considered as a promising technology for enabling the evolution of service-oriented enterprise systems towards operational aware systems. CEP effectively supports the implementation of “sense and respond” behaviours, as it enables to extract meaningful events from raw data streams originated by sensing infrastructures, for(More)
The automated specification and execution of composite services are important capabilities of service-oriented systems. In practice, service invocation is performed by client components (stubs) that are generated from service descriptions at design time. Several researchers have proposed mechanisms for late binding. They all require an object representation(More)
This paper investigates the application of SOA principles for integrating embedded devices features, typically operating in ubiquitous computing environments, with enterprise-level services and business processes. Under this perspective, we present the SAI – Service Application Integration – system as a working example of a message-oriented middleware(More)
Service-Oriented Computing (SOC) is a wide and complex research area. Despite the huge effort in both industrial and academics initiatives, several challenges need to be addressed in order to effectively realize the SOC vision. One of the most relevant issues is the need of effective, flexible, reliable, low cost solutions for dynamic service brokering and(More)
We compare two distinct (and, apparently, mutually exclusive) models of collaboration support-mechanisms, and evaluate their applicability to Internet-based economic exchanges. The first model is grounded on a bottom-up approach where decision-making is completely decentralized and global-order self-organizes out of multiplex local interactions among(More)
Care models for chronic condition treatment place point-of-care in the community and at patient’s home and imply an organized care system (“continuous care network”). The contribution of this work consists in the proposal of a service framework to support information acquisition, integration and sharing in continuous care networks. The framework is based on(More)
