Service provision and consumption platforms are more and more used to enable communication between sensors, actuators and intelligent devices, since they provide mechanisms that make possible the combination of components to create composed services. However, these kinds of platforms have limitations to adapt themselves to new and unknown devices. In this work we analyze the challenge of component or bundle communication by using the Open Services Gateway Initiative (OSGi) technology and we propose three mechanisms with the aim of contributing to flexible component communication: Common Service, Specific Service and WSIF Web Service Invocation. We provide these solutions with some architectural models and validate them through different example services. Finally we compare them regarding performance, flexibility and application complexity.

Mobile prosumer environments describe situations in which non-expert users have the possibility to create and provide their own services to others in mobility. In this paper we study the degree of variability that enables a service personalization for prosumer users and its implications regarding creation flexibility and domain adaptation. Our main contribution is the definition of a variability model by the consideration of variability points and the dependencies among them, which enrich the service personalization process, occurred during the service creation and provision phases in prosumer environments. As validation of our approach, we implement this model in a use case of mobile service creation for hospital pharmacy.

Convergent service environments are required to deal with current tendency to heterogeneity in network contents and its inherent incorporation of more types of devices demanding services from multiple domains. Efficient management architectures are required to tackle issues regarding: media content, subscriber reachability and subscriptions information coming from different types of networks in order to enable well organized communications among different environments such as: IMS, IPTv and subscribers management repositories.This paper describes the work of Eureka Mobicome project on the definition of an architecture to manage and provide services among distinct service delivery platforms (IPTV and ENUM) using IMS as a common core and proposes a compound modular architecture to set the basis for Future Internet converging service provision. The proposed architecture has been validated by the Interconnection of different prototypes deployed at Madrid (Spain) and Oslo (Norway).
