Abstract

Context-aware applications require the development of convenient frameworks. Effective mobility requires that mobile applications can integrate new sensors or new types of information. This is not possible within traditional applications, because a re-design phase is necessary. We describe in this article an agent-based framework supporting sensors' data fusion and context-aware information exchanges. An ontology-based representation of data is used. Exchanges in-between components are carried out within so-called virtual knowledge communities. An application has been designed within this framework ('Wake me up', taking place in the metro). It makes use of wearable sensor, transmitters and cell phones. The wearable sensor is used to determine the user state. Transmitters provide geographical information, and cell phones are used as personal assistants.
