Cross-Domain Service Composition in OSGi Environments

Dynamic Contextual Service Ranking

This paper explores service composition in pervasive environments with a focus on dynamic service selection. Service orientation offers the dynamism and loose coupling needed in pervasive applications. However, contextaware service composition is still a great challenge in pervasive computing. Service selection has to deal with dynamic contextual information to enable context-aware behaviors to...

Enriching OSGi Service Composition with Web Services

This letter describes combining OSGi and Web Services in service composition. According to our approach, a composite service is described in WS-BPEL. Each component service in the description may be resolved to either an OSGi service or Web Service at runtime. The proposal can overcome current limitations with OSGi technology in terms of its geographical coverage and candidate service populatio...

Automatic Service Composition with Heterogeneous Service-Oriented Architectures

Service-Oriented Architecture is widely used to program pervasive spaces such as Smart Homes because of its capabilities to handle dynamic and heterogeneous environments. It is often the case that the services required are designed and implemented using different SOAs, such as OSGi and Web Services. Most of the current composition frameworks take a two-tier approach: those services following th...

Pervasive Services on the Move: Smart Service Diffusion on the OSGi Framework

The ubiquity of wireless ad hoc networks and the benefits of loosely coupled services have fostered a growing interest in service oriented architectures for mobile and pervasive computing. Many architectures have been proposed that implement context-sensitive service discovery, selection and composition, or that use a component-based software engineering methodology to facilitate runtime adapta...
