Collaboration Instance Manager of UbiCollab 2008: Collaboration Instance Synchronization and Management in P2P network

Abstract

This report is for my research of Collaboration Instance Manager of UbiCollab project. UbiCollab want to be the platform for ubiquitous collaborative active. UbiCollab project aims to develop a distributed collaborative platform which makes people in distributed space ubiquitous collaborate with friends and colleagues. Collaboration instance manager (CIM) is a core component of the UbiCollab platform, which manage such collaborative activities. My research topics of CIM include in the P2P network development by using JXME, the data synchronization through this P2P network and how to manage these synchronized date by using a local file system. The result of my research is a CIM system, which deployed as OSGI bundle. User can use that do some collaborative active. This CIM system manage the service level of data synchronization, other modules and applications can use that to handle data synchronization between each other without know the details of how to implement it. For that purpose I first reviewed the related theories of distributed systems, ubiquitous systems, mobile systems and CSCW. After that review I researched on some alternatives for developing such system and choose the candidate technologies for my prototype. Secondly I analyzed the requirements of UbiCollab and designed the prototype. Based on that design, I implemented and tested that CIM system based on agreed common scenarios and developed a simple GUI for show the utility. Finally, I evaluate the system by analysis system requirements and scenario criteria.
