- CloudNCFS (2010-11). CloudNCFS is a file system that utilizes network-coding and erasure-coding to distribute files over mutiple Cloud storages (e.g. Amazon S3 and Rackspace). It provides fault tolerance with low repair cost. I have designed and developed the CloudNCFS software package, together with my team members. The package is written in Python and C.
- eLogbook project (2007-08). eLogbook is a Web 2.0 application developed at EPFL in the framework of the Palette European Project. It aims at sustaining collaboration and cooperation for online communities and can simultaneously serve as activity management, social networking and resources sharing system. In this project, I have conducted system design based on activity theory as well as usability analysis, together with my team members. The tools used in the project include Ruby on Rails, and MySQL.
- Palette project (2007-08). The Palette project aims at design and develop a European community-based online collaborative learning platform. Towards this aim, an interoperable and extensive set of learning services as well as scenarios of use have been designed, implemented, and validated in several learning communities. In the project, I have looked into and developed the methodology for service interoperability, together with many researchers from several European institutions. In the collaborative learning platform, the learning services are interoperated through RESTful Web services and OpenID.
- Dynamic Policy Management Framework (DPMF) for Authorization Management in Inter-Grid Environments (My PhD project) (2003-07, 09). Grid computing enables computers on different networks to share their resources in an organized way. Authorized users can deploy the resources as if they were in the same organization. The DPMF is used to support inter-Grid heterogeneous policy management. I have designed, developed and analyzed the framework and middleware. The related issues consist of virtual communities, policy schema, policy mapping, access control, and load balance. The key mechanisms of the framework includes: virtual cluster, conflict analysis, and heterogeneous policy mapping. Tools used in the project includes Globus toolkit (for Grid service development), and Java.
