RDM: Rapid Deduplication for Mobile Cloud Storage

Abstract

Cloud storages are used to expand the storage on mobile devices. It can be accessed through an internet connection. On mobile devices, network data can be expensive in terms of tariff and power consumption. Deduplication can be used to reduce the amount of data to be transferred. This paper proposes a fast deduplication system for mobile devices named rapid deduplication for mobile cloud storage (RDM). RDM is based on smart deduplication for mobile cloud storage (SDM) and rapid asymmetric extremum (RAM). RDM used RAM as the chunking algorithm instead of Rabin which is used in SDM. Our experimental results show RDM is at least 39.5% to 44.7% faster at the cost of 4.2% to 9.1% higher size after deduplication.
