| الوصف: | This thesis describes an architecture for distributed computation in mobile environments. Here, the workflow stands for the operational aspect of a work procedure. This notion subsumes the structure of the tasks, who performs them, what their operation structure is, how they are synchronized, how information flows to support the tasks and how they are tracked. The designed architecture is tested in a proof-of-concept implementation named Distributed Workflow Execution Architecture for Mobile (DWEAM). The interest in distributed workflow execution architectures is long-standing. However, there has not yet been an adequate treatment of workflow execution in mobile systems. The benefits of such a system would be collected by users who perform a coordinated task in a complex environment and must establish own coordination infrastructure to do so. Typical users are the members of emergency rescue teams, i.e.~police, fire brigade or medical personnel, when handling an incident, where the cooperation between the team members is hindered by mobility and adverse communication conditions. The communication via the gsm networks, that are used in small scale operations in urban areas cannot offer appropriate quality of service in face of escalation or infrastructure damage. The now-aged broadcast radio (i.e. walkie-talkie) typically does not support the coupling with information systems, as it is is intended for the communication between humans. We therefore consider a system architecture that addresses the communication issues, while being infrastructure-independent and supporting both the work procedures for human operators, as well as that of the information systems. First, the DWEAM problem is put into a broader context of mixed-initiative multi-actor, multi-agent systems. It is seen that DWEAM is but a single component of a larger system, called combined. The unifying description of combined is given, and the requirements for the integrated combined system are given. Following this description, we give an overview and ... |
