An evaluation method for dynamic combination among OSGi bundles based on service gateway capability

A user may use a software bundle provided by vendors to control consumer electronics (CEs) in a home network environment. Software was developed as a bundle composed of various components and registered to an OSGi service registry, thus, a user can select a suitable bundle and implement it in a service gateway. There´s no need to consider hardware when using a single bundle, because this was handled by hardware, service gateway specifications. But using several bundles to implement a business process for simultaneous control of various CEs is a different matter. If hardware resource sharing was not considered in development, then quality of service (QoS) of the business process cannot be guaranteed. Thus, we need an evaluation method for a user-defined business process, to guarantee QoS in business process modeling. This paper suggests a representative evaluation algorithm by considering metadata about bundle distribution as evaluation items, such as method response time, component response time, memory space and CPU capacity. Also, this paper suggests a business process simulator. It enables constructions of simulations for the efficiency of evaluation items and methods. A user uses a simulator to select a suitable bundle for hardware and easily makes and verifies a suitable business process for their goals.
