An OSGi-Based Semantic Service-Oriented Device Architecture

چکیده
The implementation of service-oriented device architectures (SODA) suffers from restrictions that are imposed by the use of existing syntactic technologies. Related problems include data and message-level heterogeneities among interoperating services, insufficient search and discovery of exposed services and inadequate web process composition. In this paper we propose an approach for introducing semantics in a SODA environment. Specifically we examine the introduction of data, functional and behavioural semantics and the role they play in a semantically-enabled SODA (SeSODA) pervasive environment. We put special emphasis in data semantics. We present the architecture of an OSGi-based SeSODA implementation, analyse the most critical components of this architecture and discuss implementation issues.

Context-aware personalization services for a residential gateway based on the OSGi platform
Ideally, smart homes should make its inhabitants’ lives more comfortable by anticipating their needs and satisfying their preferences. With this aim, we introduce an approach for context-aware personalized smart homes based on two main pillars: the Open Service Gateway Initiative (OSGi) platform and the Semantic Web philosophy. By combining both fields, we enrich the OSGi service-oriented archi...

This paper presents an agent-based approach into a more general service oriented architecture for addressing the requirements of accessibility content and services in an ambient intelligence context. The developed agent-based information system provides infomobility services for the special requirements of mobility impaired people. Herein, we focus in the task of integrating this multi-agent sy...
متن کاملVarious Extensions for the Ambient OSGi Framework
OSGi is a wrapper above the Java Virtual Machine that embraces two concepts: component approach and service-oriented programming. The component approach enables a Java run-time to host several concurrent applications, while the service-oriented programming paradigm allows the decomposition of applications into independent units that are dynamically bound at runtime. Combining component and serv...
