NEXUS – Distributed Data Management Concepts for Location Aware Applications
Steffen Volz, Monika Sester · 2000
Nowadays, mobile computers like subnotebooks or personal digital assistants, as well as cellular phones can not only communicate wirelessly, but they can also determine their position via appropriate sensors like DGPS. Socalled location aware applications take advantage of this fact and structure information according to the position of their users. In order to be able to assign data to a certain location, these information systems have to refer to spatial computer models. The NEXUS project, which is supported by the Deutsche Forschungsgemeinschaft (DFG, German Research Foundation), aims at the development of a generic infrastructure that serves as a basis for location aware applications. The central task of this platform deals with the data management.
