Abstract

Mobile computing is growing in popularity due to continuing improvements in mobile devices and their connectivity. Collaboration systems enable users at geographically distributed locations to collaborate each other. Community Grids Lab's GlobalMMCS is a Web Services based, integrated videoconferencing system that allows heterogeneous clients to join the same session. Integration of mobile devices into the Web Services based collaboration system will give mobility to users and heterogeneity to the system. However, there are performance limitations if we use the current SOAP approaches to integrate mobile applications with Web Services based collaboration systems, especially for multimedia applications. In this paper, we propose a SOAP Infoset preserving Flexible Representation and its specialization for mobile computing environment - Handheld Flexible Representation (HHFR). We provide a flexible representation of binary encoding with a description file for message format and include a QoS framework in the architecture, such as reliability and security.
