Dynamic execution environments for ubiquitous computing service

Ubiquitous service provides various functions to users by process of context acquisition and reasoning from ubiquitous environments. These services usually cooperate with other services for acquisition of context or providing service to users. In order to support the service execution, there are a lot of researches which are designed based on OSGi framework. OSGi framework supports the service execution environments and syntax based service matching. In previous studies, they have not been able to support the service mobility and interoperability effectively. This study proposes a dynamic execution environment for ubiquitous service which supports service mobility among service gateway and service matching based on semantic information. The proposed dynamic execution environment has advantages of interoperation and integrating the heterogeneous devices by applying these standard interface technologies and service discovery and dynamic service compositions using semantic information.
