An ongoing topic in wireless sensor networks is the aim to save energy. This often requires optimized protocols with a reduced performance and robustness. One currently successful wireless technology with a very strict low-power design is EnOcean. This paper analyzes its protocol performance by deriving an analytical performance analysis model that expresses different protocol aspects and devices'...
The domain of building automation consists of system designs with huge complexity, whereas the major part is the room automation designs. These designs are realized by prefabricated devices which are offered by various manufacturers that support a broad spectrum of functions. This results in the problem of choosing a combination of devices which optimally realize the requirements. In this paper, a...
Embedded systems are used in many domains today. However, the design process of these systems is complex and time-consuming. In automation domains the complexity can be decreased by using function block based designs to specify the functionality of the system to be created. But this has to be done still manually. This paper introduces an approach to generate such function block based designs automatically...
Existing technologies in home and building automation system interface offer extensive possibilities to improve the individual life. However, especially seniors have large problems with the usually technology-centered user interfaces and avoid the technology. Instead, they are used to speech, which leaves speech-recognition and -synthesis suitable technologies for barrier-free interfaces. However,...
