Dynamic Reconfiguration of Application Logic During Application Migration

During migration of an application from a source to a target device, its application logic often has to be adapted to the new situation. The new situation can for instance be characterized by different hardware resources or a different usage context . Therefore, the application logic has to be adapted automatically to the new context in order to provide the most suitable behaviour before and after migration. We consider application logic that consists of components which interact with each other through well-defined interfaces. In order to adapt the behaviour of the application logic, components can be added, removed or replaced. In this chapter we introduce a concept which enables the dynamic reconfiguration of component-based applications based on context information during the migration process. Our concept enables a technology independent specification of adaptation behaviour. Furthermore, we support the specification of an application without referencing application components directly. In that way it is possible to integrate new components into applications that were not known during application development time.
