We describe our experience creating a robots community using standard hardware and software – the Windows CE operating system, XScale development boards, and LEGO Mindstorm actuators. We focus on an open and extendable distributed robotics system, which in contrast to most existing proprietary robotics systems, supports cost-effective integration and(More)

Asset tracking offers high potential to improve efficiency of warehouse management. Typically the tracking is done employing RFID technology. As yet however, most goods are not prepared with RFID and it would require investment in costly hardware, infrastructure, and process adaptations. WLAN-based asset tracking is getting ready as a cost-effective(More)
In complex distributed environments, it is important to achieve high degree of machine-to-machine interaction, not only on a functional, but on a semantic level. Therefore, we propose the NOMADS (Networks of Mobile Adaptive Dependable Systems) Republic, a vision of the future community open to all interested hardware and software entities, and based on(More)
Dependability should be considered throughout the phases of the SOA life cycle. This article proposes the application of a service level management approach to address dependability and presents dependability-related activities for every stage (Model, Assemble, Deploy, and Manage) of the SOA life cycle. Furthermore, we describe the concepts and the(More)
Web-services based systems present challenges for service level enforcement. Contrary to typical enterprise architectures where we are in control of all services and can easily specify and monitor service levels, here we need self-adapting approaches. The paper proposes techniques for service level enforcement in the context of a four step approach. The(More)
