In ubiquitous computing environment, OSGi has applied to many areas such as digital mobile phones, vehicles, telematics, embedded appliances, residential gateways, industrial computers, desktop PCs, and high-end servers including mainframes. Therefore, interoperability is required for remote OSGi services which are built on various devices. In this paper, we proposed a method which was able to interoperate remote OSGi services using RMI paradigm. RMI is a representative middleware technology in distributed computing environment. The suggested method is based on the standard OSGi technology. It is possible to provide remote OSGi service registration, finding, and binding methods which were suitable for the OSGi service-oriented architecture. We also provided reliability of the dynamic remote OSGi services by maintaining consistent properties of them, and we could provide location transparency of the remote OSGi services by generating proxy bundles and proxy services dynamically.
