Grids for Real Time Data Applications

We describe our work in building support for streaming data services for Geographical Information System Grid services. We examine how streaming approaches may be used to increase data service performance for transporting XML messages. Similarly, streaming versions of traditional static map services may be combined with general audio/video session management capabilities to build collaborative, annotatable shared maps. Distributed services linked through messaging substrates require information and broker management capabilities, and we describe our research here. Finally, we discuss efficient XML representation techniques that can be used to increase performance of Web Services and support Web enabled devices.
