An approach towards a framework that enables the static composition of real-time applications from existing ubiquitous services is presented. This framework allows to announce services (specifying their QoS requirements in terms of real-time parameters, such as Worst Case Execution Time, WCET), to discover services that perform a certain functionality and to select the set of those discovered services that will be part of the application to be created. Such service set selection is based on the fulfillment of the QoS requirements of the application. The composition is static, i.e., all services required to create an application have to be discovered before launching the whole application. We describe the composition model of the framework and its implementation on top of Jini.
