Abstract

A high adaptable middleware has been an essential platform to provide more flexible services for multimedia, mobile, and ubiquitous applications in ubiquitous computing environments. In addition, the persistent services of these application systems and their middleware in ubiquitous computing are required so that they can be aware of the frequent and unpredictable changes in users’ requirements as well as environmental conditions and adapt their behavioural changes. However, current approaches for supporting adaptability have made applications themselves trigger and execute an adaptive mechanism when the underling infrastructure notifies them about any changes. In this paper, we propose a novel component-based context-adaptive model for context-awareness middleware to support efficiently dynamic adaptation of application services. We also demonstrate the current implementation of the context-adaptive middleware that help applications to adapt their ubiquitous computing environments according to rapidly changing contexts such as user-specific preferences, application-specific preferences, and low-level configurations.
