Computers and especially computer networks have become an important part of our everyday life. Almost every device we use is equipped with a computer or microcontroller. Recent technology has even boosted this development by miniaturization of the size of microcontrollers. These are used to either process or collect data. Miniature senors may sense and collect huge amounts of information coming from nature, either from environment or from our own bodies. To process and distribute the data of these sensors, wireless sensor networks (WSN) have been developed in the last couple of years. Several microcontrollers are connected over a wireless connection and are able to collect, transmit and process data for various applications. Today, there are several WSN applications available, such as environment monitoring, rescue operations, habitat monitoring and smart home applications. The research group of Prof. Elaine Lawrence at the University of Technology, Sydney (UTS) is focusing on mobile health care with WSN. Small sensors are used to collect vital data. This data is sent over the network to be processed at a central device such as computer, laptop or handheld device. The research group has developed several prototypes of mobile health care. This thesis will deal with enhancing and improving the latest prototype based on CodeBlue, a hardware and software framework for medical care.
The thesis at hand evaluates Open Source Business Process Management (BPM) Systems in the context of the R4eGov1 Project. The provision of concepts and tools to support and enable interoperability in pan-European networks of pubic administrations is one of the major objectives that R4eGov is aiming at. Thereby a strong focus lies on the interoperability of cross-organizational processes from the viewpoint of modeling, execution and monitoring. BPM can increase the effectiveness and efficiency of cross-organizational processes by restructuring them towards the needs of the entities involved. BPM is dependent on BPM systems that combine technologies of process modeling, business process analysis and execution along with their integration into adequate runtime environments and rule engines. The evaluation that is performed within the thesis investigates how far BPM systems can support several requirements of interoperability that have been developed by the R4eGov project. It also targets at analyzing those BPM system according to generic requirements on BPM and software tools. The investigation is build upon common BPM theories and standards for modeling business processes. It describes the origin and interdependencies of BPM and Workflow Management (WfM), highlighting similarities and differences from the technological and historical perspective. Moreover, it introduces web service standards and technologies that are used to build service-oriented architectures allowing greater flexibility in BPM. In addition the thesis introduces methods and best practices to evaluate software tools. It contains an evaluation framework for BPM tools that has been based on the software product evaluation standard ISO/IEC 14598. The evaluation framework comprises the definition of an R4eGov scenario and a catalogue of criteria for evaluating a set of selected Open Source BPM systems. The definition of the catalogue of criteria is build upon generic requirements on BPM systems and those that are specifically to R4eGov. The chosen methods and the core elements of the evaluation framework will be applied to the selected BPM systems Intalio BPMS,NetBeans IDE, and JBoss jBPM. Finally the results of the applied R4eGov scenario and of the applied catalogue of criteria are being discussed by highlighting individual strengths and weaknesses of the systems.
