Context-awareness has become a necessity for adaptable intelligent applications and services. It is crucial for ubiquitous and pervasive computing because the context of a user or device serves as the source of information to adapt services. In this paper, we propose a modular context management system that is able to collect, transform, reason on and use context information to adapt services. By employing a component-based approach, we enable our infrastructure not only to support context-aware adaptation of services, but also to support adaptation of the context management system itself at deployment time and at runtime. This self-adaptation is based upon the service requirements and the current context of the device, such as the current resource usage or other devices in the neighborhood, resulting in an adaptive context management system for improved quality of service.
