As the Wireless sensor/actuator networks (WSNs) started to be deployed in enterprise scenarios, the need of integration of WSN applications with enterprise business processes has emerged. Creation of the WSN applications in enterprises, however, requires much low-level programming, and this causes the loss of focus on the high level goals. Therefore a model-driven approach is needed. As Business Process Model and Notation (BPMN) is the de-facto standard of modeling business processes, it is suitable for companies to use BPMN for the model-driven approach. In this work, first we analyze the WSN properties, which distinguish them from traditional IT systems. Thereafter, we analyze the general properties of BPMN which need to be preserved to keep the common understanding that BPMN brings. As a result, we end up with some properties that are relevant with modeling WSN processes in BPMN. From these properties, we derive the requirements for modeling WSNs and propose some extensions to standard BPMN. These extensions include a new type of task, a new type of pool and a new grouping structure to set performance goals of the corresponding WSN. Afterwards, we analyze the current state of art to compare our approach with other possible approaches. Specifically, we compare our approach with standard BPMN, BPM4People extensions with respect to requirements and show that why our proposals provide a more comprehensive and suitable approach.

Human-centric processes are part of most organizations and their execution steps are typically not known initially. Consequently, standard business process modeling approaches are not suitable for modeling informal processes because they typically concentrate on the explicit modeling of the execution steps. In this work, we analyze properties of informal processes and requirements for supporting their correct enactment. We review existing approaches and evaluate their suitability in terms of modeling informal processes. Based on these results, we present a resource-centric approach by employing the concept of Informal Process Essentials which is used to create executable informal process models with dynamically changing interrelated resources.

Abstract. Traditional workflow and activity-centric coordination offers limited process support to human collaborators when unanticipated situations predominate. Under such circumstances, informal processes focus on provisioning relevant resources for achieving collaboration goals. Resources include interaction mechanisms such as shared artifact, social networks, and publish/subscribe information dissemination as complex situations typically demand the close collaboration among multiple human process participants. Currently, however, there exists a gap between (i) selecting and configuring suitable interaction mechanisms (collaboration level) and (ii) deploying the respective collaboration platforms (IT level). In this paper, we present an approach and techniques for transforming collaboration structures into automatically deployable informal processes. We demonstrate how our tools support the specification of desirable collaboration capabilities subsequently deployed to multiple MediaWiki instances.
