Modeling Context-Aware Behavior by Interpreted ECA Rules

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 role-based 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.

Personalization of End User Software on Mobile Devices

Applications for mobile devices, especially mobile phones, are rarely used today - apart from games. They neither take the special features of each device into account nor the individuality of the user who usually has a much closer emotional relationship to her mobile phone than to many other technical devices. Useful and successful mobile applications can thus be presumably only those that address these deficits. In this paper, we present a novel approach for solving these problems by personalizing Java based mobile applications. The concept centres on a powerful and flexible XML information model that can easily be utilized for adding personalized data and features to an application. The information is weaved into the code by a pre-processor prior to compilation. We also present an example of its usage and discuss some of the consequences
