An Agent-Based Framework for Context-Aware Servicesan agent based framework that supports “pluggable” service logic in the sense that the service developer can concentrate on coding the service logic independently of the underlying middleware. Following the description of the framework, we elaborate on how it has been used to support two prototype c

Secure Authentication and Accounting Mechanism on WLAN with Interaction of Mobile Message Servicey systems. Therefore, we overview main problem on existing EAP-MD5 authentication mechanism on Wireless LAN and propose a SMS(Short Message Service) based secure authentication and accounting mechanism for providing security enhanced wireless network transactions against those attacks.

Dynamic Conflict Detection and Resolution in a Human-Centered Ubiquitous Environmented that CCM can successfully detect and resolve the runtime conflicts caused by multiple devices interconnected in a ubiquitous environment. It can also be used to detect the potential conflict risk during the service registering phase so that computerized devices are deployed to improve the human interactions with them.

Learning Topologies of Situated Public Displays by Observing Implicit User Interactionsf one display. This can be used for example to create continuous ‘shows’ spanning multiple displays while people pass them. To create the model, we use Bluetooth connection data of mobile phones people carry, and employ the EM algorithm to estimate mean travel times for different paths people take.

Learning Situation Models for Providing Context-Aware Services, the initial situation model is acquired by applying an automatic segmentation process to sample observation of human activities. This model is subsequently adapted to different operating environments and human preferences through interaction with users, using a supervised learning algorithm.

Ambient Intelligence in Assisted Living: Enable Elderly People to Handle Future Interfacesby various user-interfaces is an absolute necessity. In this article, we present an Assisted Living Laboratory that is used to train elderly people to handle modern interfaces for Assisted Living and evaluate the usability and suitability of these interfaces in specific situations, e.g., emergency cases.
