“…A mobile process is defined as a piece of mobile code representing a goal-oriented composition of services which can be migrated to other (mobile or stationary) devices in order to share the functionality provided by these nodes [10]. Figure 1 shows a process initiator who is himself not capable of executing an ad-hoc process requiring several mobile and stationary services.…”

“…In case the direct vicinity does not provide the required service, the process description can be migrated to another remote device in order to enable the execution in a different vicinity. It was shown that this strategy of process migration increases the probability that an (ad-hoc) process can be executed successfully [10] -especially in mobile environments where resources are often locally unavailable.…”

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.

Abstract. Use of web services also on mobile devices becomes increasingly relevant. However, realizing such mobile web services based on the standard protocol stack is often inappropriate for resource-restricted mobile devices in dynamic networks. On the other hand, using specialized alternative protocols restricts compatibility with traditional service applications. Thus, existing approaches often do not allow to integrate heterogeneous service instances dynamically, as it is, e.g., required for executing mobile service-based business processes. In order to adequately support such more complex and dynamic applications, this paper presents a lean and flexible system architecture which supports both mobile web service consumers and providers by allowing to integrate multiple protocols depending on their capabilities and to dynamically access suitable service instances at runtime. As a proof of concept, the paper shows an exemplary combination of practically relevant protocols for resource-limited devices based on WSDL, ASN.1 and overlay transport and presents its integration in a prototype scenario for supporting decentralized mobile business processes.

SUMMARYMiddleware support for advanced pervasive applications includes dealing with heterogeneous systems and dynamic changes of execution environments. If applications are context aware, they are able to detect such changes at runtime and react to them accordingly. Furthermore, they can also proactively adapt to upcoming situations by making accurate assumptions about future contexts. However, the design of reusable middleware support for such future‐context‐aware applications is still challenging as a supporting prediction system has to be generic, but at the same time has to provide potential for high accuracy and efficiency.This paper proposes a concept for the development of future‐context‐aware applications on the basis of the novel approach of structured context prediction. As a framework, this approach allows for integrating domain‐specific knowledge and facilitates application, combination, and implementation of suitable prediction methods. In addition, specific runtime mechanisms for distribution of knowledge and adaptation of prediction tasks are proposed, which enable useful context predictions even for dynamic applications. The overall development process as well as practical experiments with the prototype framework is illustrated by two use case scenarios—demonstrating that both high accuracy and efficiency of future context predictions are achievable and even ad hoc context predictions can be supported this way.
