DEECo – an Ensemble-Based Component System

Abstract

The recent increase in the ubiquity and connectivity of computing devices allows forming large-scale distributed systems that respond to and influence the activities in their environment. Engineering of such systems is very complex because of their inherent dynamicity, open-endedness, and autonomicity. In this paper we propose a new class of component systems (Ensemble-Based Component Systems – EBCS) which bind autonomic components with cyclic execution via dynamic component ensembles controlling data exchange. EBCS combine the key ideas of agents, ensemble-oriented systems and control systems into software engineering concepts based on autonomic components. In particular, we present an instantiation of EBCS – the DEECo component model. In addition to DEECo main concepts, we also describe its computation model and mapping to Java. Further, we outline the basic principles EBCS/DEECo development process.
