ABSTRACT
Service Component Architecture (SCA) defines how to create components and how to combine those components into complete applications. SCA defines a general approach to doing both of these things at design time of applications. In ubiquitous, we consider dynamic factors such as frequently movement of user or device location and change of service status. SCA does not consider about that, but this specification proposed good solution about service composition. For this reason, we suggested the service composition approach, which is extended of SCA. Our approach supports dynamic service composition, which is considered the dynamic factors of ubiquitous environment. In addition, it reflects the user requirement like that what kind of service to do in what order. It also supports coordination of service when the client can no longer use the service because it is putted off the power or has another problem.

Semantics-based dynamic service composition
Complex services may be dynamically composed through combining distributed components on demand (i.e., when requested by a user) in order to provide new services without preinstallation. Several systems have been proposed to dynamically compose ...
Research in Enterprise Applications of Dynamic Web Service Composition Methods and Models
ISECS '09: Proceedings of the 2009 Second International Symposium on Electronic Commerce and Security - Volume 01The paper summarizes current technologies of dynamic web service composition. Then, based on the existing technologies, we raise a new solution for dynamic web service composition. We make use of the knowledge of domain ontology. On the one hand, the ...
Dynamic service composition using semantic information
ICSOC '04: Proceedings of the 2nd international conference on Service oriented computingDynamic composition of complex services from primitive components brings flexibility and adaptability to future applications. By properly selecting and combining components on dand, applications would adapt to individual user preference and would ...
