Context Framework for Mobile User Applications

Goal of this project work is to find new methods, dealing with abstract semantic description of objects and their interaction and to manifest this methods in a software artefact. Forthcoming research and new hardware concerning kommunikation technology through radio (IEEE802.11b, Bluetooth, Rfid) enables the use of interconected sensors and actors. This intelligent sensors and actors are embedded in their environment and are collecting masses of unstructured data about this environment. The following research issues are investigated: Context Sensing: Definition of generic methods, to gain context information event triggered and time triggered (via polling) Representation of context information: To find a suitable abstract representation to describe semantic context information. Integration of abstract rules: To find a context rule syntax definition, in order to control interaction of heterogeneous devices. Communication: Usage of popular transport protocols to enable the retrieve of context information
