SLCA, Composite Services for Ubiquitous Computing

摘要

Main concepts to handle in ambient computing applications are hard to integrate at the same time. After studying mid-dlewares handling a part of the challenge, and after studying possiblities of main paradigms in name of CBSE and SOA, we present our Service Lightweight Component Architecture (SLCA) model, based on three main paradigms: Web services, enabling entities interoperability, dynamic discovery, and distribution; lightweight component assemblies to create composite Web services, allowing a high dynamic-ity; and finally events, giving applications reactivity and a maximal decoupling between entities, thus enabling an even higher dynamicity. This leads to conciliate both service oriented and event driven approaches in a new way to manage a graph of cooperating services in ubiquitous systems.
