A Site Management System (SMS), controlling and coordinating domestic, commercial and industrial sites has an inherently dynamic computer network. Devices can enter and leave the network at any moment because of malfunctions, mobility or new components. Moreover, the size of the network continuously increases, thanks to adding networking capabilities to new ranges of appliances, from electrical plugs...
Building automation is concerned with monitoring and control of building services equipment. Over the last years, many different control network protocols have materialized for this task. Ideally, an all-in-one solution would be desired which allows total control of all conceivable scenarios. Even despite the long timespan of development, no single specific protocol has yet emerged that covers all...
This paper proposes a web-based architecture to enable information retrieval and appliance management for a Home Energy Management (HEM) system. With the proposed architecture, homeowners can monitor their basic energy usage information, and can perform necessary appliance management based on their pre-defined load priority, preferences, and comfort settings. The proposed architecture is designed...
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...
The increasing ubiquity of mobile embedded systems has been matched by the evolution of a variety of wireless network standards and technologies. The major constraints of wireless embedded systems are limitations of communication bandwidth, processing capabilities, and battery power. Remote wireless embedded systems often act as sensors, which provide data to a certain community. The exchange of data...
