A Proposal for Mobile Collaborative Work Support Platform Using an Embedded Data Stream Management System

This paper presents a mobile collaborative work support platform that uses an embedded data stream management system (mDSMS). The collaborative work that we focus on includes activities not only within typical organizations, but also in organizations such as disaster relief centers. These activities are modeled using a meeting-oriented coordination model of distributed systems, because such activities are temporally coupled and referentially uncoupled. We develop a collaborative work support system for Android devices that uses data stream management, which is a key technique of the model. One of the features in mDSMS is a multilayer query scheduling feature that is capable of various holding times for activity messages and assures the timeliness of message processing. We present the architecture and design of mDSMS on the Android platform as well as preliminary evaluation results.
