Sharing File System for Campus Wide-Workgroups

This paper describes the implementation of a file system based distributed authoring system forcampus-wide workgroups .In this we overcome the difficulty in changing a single document by differentgroup members. Prior approaches operate on only specific documents but our system operates on any type ofdocument. Each group member maintains one updatable copy of shared document. We also hoard read-onlycopies of each of these updatable copies in any other group member’s node. All these copies are propagatedto other group members at a rate that is solely dictated by the wireless user availability. Our user space filesystem prototype exhibits acceptable file system performance. A subjective evaluation showed that themoderation operation was intuitive for students.
