An iPOJO Component-Based Workflow Architecture in Ubiquitous Cloud Environments

Abstract

The growth of innovative services from various ubiquitous sensors and devices provides huge potential for ubiquitous computing applications and systems. However, to be able to benefit from the new developments, current service middleware technology needs to catch up with the rise. One of the effective solutions is to build up value-added, composite services out of basic services available in ubiquitous environments. Thus, this paper proposes to extend the iPOJO, a service-oriented component model, to enable a workflow engine, achieving service composition in OSGi-enabled ubiquitous environments. The features of modularity and service orientation have been the main emphasis of our workflow system design.
