A Survey of Service Composition Mechanisms in Ubiquitous Computing
نویسنده
چکیده
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.

متن کاملA Survey on Service Composition Middleware in Pervasive Environments
The development of pervasive computing has put the light on a challenging problem: how to dynamically compose services in heterogeneous and highly changing environments? We propose a survey that defines the service composition as a sequence of four steps: the translation, the generation, the evaluation, and finally the execution. With this powerful and simple model we describe the major service...

Ubiquitous computing provides a dynamic access to different functionalities of networkable electronic devices.

Alternatively, users need to be provided with means to express their requirements, ch...
