Abstract

The software architecture of distributed systems is about to change due to new requirements of modern mobile devices. New network techniques, like ad-hoc radio communication or peer-to-peer networks allow mobile devices to sense their environment and to interact with other devices dynamically. This paper presents a cutting-edge way to describe objects and their interaction, also called context, as well as the possibility to configure such interaction scenarios. A lookup mechanism collects information about the environment and a rolebased classification is responsible for identifying possible interaction partners. Furthermore the configuration of scenario behavior with context rules is introduced. Finally a comparison with already existing context frameworks is given and a practical emergency scenario configuration is shown.
