Proxy-based aggregated synchronization scheme in mobile cloud computing

Abstract

Recently, data sharing applications among mobile users in cloud computing platforms (e.g., Dropbox and Google Drive) are very popular. In such applications, a cloud server is responsible for synchronization among mobile users and thus the synchronization traffic can be significant when the data are frequently updated and shared by many mobile users. To address this problem, we propose a proxy-based aggregated synchronization (PAS) scheme in which the proxy server and the cloud server conduct localized and aggregated synchronizations, respectively. Preliminary simulation results demonstrate that PAS can reduce the synchronization traffic by 83.1%.
