Electric power industries have expanded the automation of their networks in recent years to meet the growing demands for improvements in services. The introduction of the concept of Smart Grid, the increased availability of smart devices and improvements in telecommunications are key factors for that. Besides the benefits in control and management that this concept brings, there are some technical...
This paper describes a model-driven implementation of a standard-compliant Customer Energy Manager (CEM). The advantage of the proposed implementation methodology over conventional techniques is the automatic support of standard data models and the possibility to express CEMS logic in a protocol-independent way. In particular, the logic can be expressed as a state machine, with language constructs...
The idea of the Internet of Things, which emerged in recent years, became one of the main fields of interest in industrial and academic research. The Constrained Application Protocol (CoAP) is one of the technologies aspiring to a standard in the IoT world. CoAP was designed to provide a low-overhead, machine-to-machine communication for constrained devices in a way similar to HTTP. In this paper...
Distributed software systems are characterized by increasing autonomy. They often have the capability to sense the environment and react to it, discover the presence of other systems and take advantage of their services, adapt and re-configure themselves in accordance with the internal as well as the global state. Testing this kind of systems is challenging, and systematic and automated approaches...
The UNICORE grid system provides a seamless, secure and intuitive access to distributed grid resources. In recent years, UNICORE 5 is used as a well-tested grid middleware system in production grids (e.g. DEISA, D-Grid) and at many supercomputer centers world-wide. Beyond this production usage, UNICORE serves as a solid basis in many European and International research projects and business scenarios...
