T.: Requirements for a component framework of future ubiquitous computing

System software for future computing environments be-comes more complex and heterogeneous. Portability be-comes one of the important properties of the future system software. Component-based systems contribute the porta-bility issues. However, component behaviors cause depen-dencies among components and thus prevent consistent sys-tem compositions. We have built a component-based Java virtual machine and tried three configurations with compo-nents in order to investigate the inter-component dependen-cies and the effect of the component behaviors. Also, this paper proposes requirements for a component framework for future ubiquitous computing.
