OSGI-BASED DYNAMIC SERVICE MANAGEMENT METHOD FOR CONTEXT-AWARE SYSTEMS

摘要

An OSGi-based dynamic service management method for context-aware system is provided. By adding a service bundle for service implementation to an OSGi framework, a service lifecycle is separately managed. For this purpose, the service bundle has several service implementations, and a service factory object is generated as many as the service implementations. The lifecycle of the service is managed. The service factory object installs and uninstalls the service. Accordingly, even when various sensors and devices are newly added to the context-aware system, a corresponding service can be installed and uninstalled at any time, thereby providing a dynamic management.
