“…As many of such processes are running in the background, an appropriate interaction module needs to emerge explicitly in case a new user interaction is required. Consequently, the interface description has to be specified within the mobile process in order to be able to migrate from one device to another − abstracting from particular interaction modalities, platforms, contexts and other device properties [5]. The descriptions must thus be capable of being integrated into existing process description languages and allow for data exchange with superordinated data flow constructs to enable control flow decisions based on data entered or automatically processed in previous (automated or manual) activities.…”

“…[4,9]). In difference to traditional approaches in this field, the concept of mobile processes [5] focuses on the cooperation among devices in a mobile vicinity. A mobile process therefore represents a goaloriented composition of services which can migrate to other (mobile or stationary) devices in order to share the functionality provided by these nodes.…”

“…This is necessary since the type of services and applications provided in the actual execution environment cannot be determined at design time − but results from the available resources and technologies during runtime. Furthermore, a mobile process can involve arbitrary tasks and heterogeneous devices − and therefore also different contexts which cannot be foreseen in advance [5,6]. Examples for such contexts are different service qualities, different network connections, and different device characteristics such as processing power, memory capacity or display size and resolution.…”

Abstract. An important focus of recent business process management systems is on the distributed, self-contained and even disconnected execution of processes involving mobile devices. Such an execution context leads to the class of mobile processes which are able to migrate between mobile and stationary devices in order to share functionalities and resources provided by the entire (mobile) environment. However, both the description and the execution of tasks which involve interactions of mobile users still require the executing device and its context to be known in advance in order to come up with a suitable user interface. Since this seems not appropriate for such decentralized and highly dynamic mobile processes, this work focuses on the integration of manual tasks on the respective ad-hoc creation of user interfaces at runtime. As an important prerequisite for that, this paper first presents an abstract and modalityindependent interaction model to support the development and execution of user-centric mobile processes. Furthermore, the paper describes a prototype implementation for a corresponding system infrastructure component based on a service-oriented execution module, and, finally, shows its integration into the DEMAC (Distributed Environment for Mobility-Aware Computing) middleware.

“…The state of the process (process state) and the state of each single activity (activity state) are represented by an element of the existing migration state model (cp. [9]). Furthermore, a set of activities can be referenced as start-activities to mark the next activity to be executed after process migration.…”

Process as a Service (PaaS) addresses modeling, execution and management of business processes without running extensive and costly process management software. Such a flexible outsourcing strategy is especially advantageous in the context of mobile devices and services which are increasingly relevant for contemporary business activities. Based on the concept of context-based cooperation, this paper proposes a PaaS solution for mobile participants which enables them to share existing local and remote resources and to utilize PaaS functionality of cooperating providers in a userdefined way. The approach is realized and evaluated by an extended prototype implementation of the DEMAC (Distributed Environment for Mobility Aware Computing) platform.
