Composition of services, i.e., providing new services by combining existing ones, is a pervasive idea in ubiquitous computing. We surveyed the field by looking at what features are actually present in technologies that support service composition in some form. Condensing this into a list of features allowed us to discuss the qualitative merits and drawbacks of various approaches to service composition, focusing in particular on usability, adaptability and efficiency. Moreover, we found that further research is needed into quality-of-service assurance of composites and into contingency management for composites—one of the concerns differentiating service composition in ubiquitous computing from its counterpart in less dynamic settings.
