Adaptivity in Risk and Emergency Management Applications on Pervasive Grids
The Grid Component Model (GCM) is becoming a promising development platform for flexible and adaptable grid applications. Recently, a set of mediator components has been proposed for providing a uniform and integrated platform to access grid middleware, services, and resources from an application. In this paper, we present our experiences with building such mediator components using GCM, focusing on two functionality areas. First, we show how application adaption support can be realized via mediator components, based on a set of component controllers through which the application components can be adapted and steered. Second, we show how a service and resource abstraction layer can be controlled at runtime from the mediator components.
