Energy efficient deduplication system exploiting similarity information

Abstract

In this paper, we propose a file deduplication system considering file similarity information. The key idea of this paper is to reduce the energy consumption of a mobile device by minimizing network traffic. The proposed system can detect duplication ratio of a file using file similarity algorithm. In this work, for a file with high data redundancy, data deduplication is performed during file transferring, otherwise, conventional file transfer scheme works without data deduplication. We implemented Fixed-length Chunking and Variable-length Chunking deduplication algorithm using file similarity. Experiment result shows that the proposed scheme significantly reduces energy consumption of data deduplication. © 2012 Springer Science+Business Media Dordrecht.
