Abstract :
Combining existing services to create new pervasive computing services involves special design considerations, including context awareness, contingency management, device heterogeneity, and user empowerment. Service composition is a natural concept around which to structure pervasive systems and individuate parts of them that are suitable for contingency management, application, storage, and so on. The notion of service composition also provides a natural frame for addressing systemic issues such as performance, usability, and security. In this case, such characteristics aren´t determined by a particular service but rather by the software architecture-how services are combined.
