Energy Efficient File Transfer Mechanism Using Deduplication Scheme

In a mobile device, it is important to minimize battery consumption when we operate an application. In this paper, we propose an energy efficient file transfer scheme for mobile device by exploiting deduplication scheme. Generally, a mobile phone needs more power for WiFi work rather than CPU work, therefore we have to minimize WiFi work. We can minimize the number of packets by adapting deduplication which consumes lots of CPU power. Deduplication work consumes additional CPU power during data hashing, however overall energy consumption can be diminished. Experiment result shows that the proposed scheme significantly reduces battery consumption if a file has over 5% SRP(Space Reduction Percentage).
