U-Storage: A New On-line Storage System for Ubiquitous Environment

In this paper, we propose a new storage system architecture called as U-Storage (ubiquitous storage system). U-Storage allows a user to access an on-line storage with any type of information devices that are able to connect to Internet. The on-line storage is virtualized to the user's information devices as a local hard disk or a memory card by our U-Storage. With devices supporting U-Storage, users can read and write their data anytime and anywhere without downloading and uploading operation.
