Storage capacity is a constraint for current mobile devices. Mobile Cloud Computing (MCC)
is developed to augment device capabilities, facilitating to mobile users store/access of a
large dataset on the cloud through wireless networks. However, given the limitations of
network bandwidth, latencies, and devices battery life, new solutions are needed to extend
the usage of mobile devices. This paper presents a novel design and implementation of a
hierarchical cloud storage system for mobile devices based on multiple I/O caching layers …
