Context-aware self-adaptive applications monitor and exploit knowledge about external operating conditions and adapt to changes in the execution context. Modern smartphones are equipped with several sensors, like GPS sensor or accelerometer. Additionally, context reasoners and external context providers exist. Thereby, it's possible that several context providers offer information of the same type (e.g. location) but differ in quality levels (e.g. accuracy), representations (e.g. position represented in coordinates and as an address) and cost (e.g. battery consumption) for providing the information. Therefore comprehensive support is required for selecting and activating ((de-)activation of local providers to save resources) one of the context providers.
