This paper proposes an architecture that allows continuous and ubiquitous access to capabilities, i.e. the functionality provided by these devices, to solve some of the problems associated to dynamic mobile environments. Focusing on the issue of continuous capability invocation, this work uses a set of software engineering patterns for defining the communication architecture, which support the most common types of resource access. Finally, a contribution to resource access management is described, through the implementation of two algorithms and their evaluation through two different use cases.}, booktitle = {Proceedings of the 5th {International} {Symposium} of {Ubiquitous} {Computing} and {Ambient} {Intelligence} ({UCAMI} 2011)}, author = {Alcarria, Ramon and Aguilera, Unai and Robles, Tomas and L\xf3pez-de-Ipi\xf1a, Diego and Morales, Augusto}, month = dec, year = {2011}, keywords = {Mobile, Service discovery, capability harmonization, dynamic capabilities, java me, mio} }']

Users have the possibility to create and provide their own services to others. Due to mobility, resources used to provide their services change and disappear continuously causing the disruption of the execution and the consumption process. This paper proposes an architecture for mobile service prosuming which tackles the previous problems. It provides a decoupled vision of the different participants in the prosumer environment using various concepts: services, components and capabilities. These concepts enable a dynamic and continuous resolution process during prosuming and also the creation of composite services. This work presents an architecture for mobile devices which supports continuous service execution in a prosumer environment also including composite services. Components are resolved with available capabilities which are selected using restrictions performing a matching process. Due to the heterogeneity of computational resources in mobile devices, a dual approach for matching is proposed: semantic for powerful devices, and syntactic for limited ones.}, booktitle = {Proceedings of the 4th {Symposium} of {Ubiquitous} {Computing} and {Ambient} {Intelligence} ({UCAMI} 2010)}, author = {Aguilera, Unai and Almeida, Aitor and Ordu\xf1a, Pablo and L\xf3pez-de-Ipi\xf1a, Diego and de las Heras, Rafael}, month = sep, year = {2010}, keywords = {Mobile, Service discovery, capability harmonization, dynamic capabilities, java me, mio}, pages = {229--238} }']

The industry has developed the UDDI registry to enable the register of services and to make them available to their users. However, the keyword-based search of UDDI frequently return no results because there is no relation between the concepts used by the providers and those used by the clients. This paper presents an UDDI registry extended with semantic functionality by means of a generic semantic discovery algorithm that is not bound to any specific ontology or concepts from it.
