Enhancing Residential Gateways: OSGi Service Composition

http://ieeexplore.ieee.org/xpls/abs_all.jsp?arnumber=4140904

Scenario

Home Security Service:

Fire

• ringing alarm
• unlocks the doors
• calls the fire station
• informs John using the most appropriate device

Intrusion

• locks the doors
• calls the police
• informs John

They propose a BPEL like description for providing a composition contract where a virtual bundle gets loaded to the OSGi ServiceRegistry with the BPEL specification for the service, registers itself with the BPEL engine and enables the engine to use the loaded BPEL. The BPEL is then used by the system to do an orchestration of services in the OSGi ServiceRegistry.

OWL-OS/OSGi is used as a semantically enabled OSGi framework in order to provide semantic enhancements to OSGi. The partner link is expanded with some more elements to incorporate semantic information for the partners providing the desired methods or porttypes.
