Globally adaptive data prefetching mechanism for mobile network applications

Abstract

This paper presents an approach named Multiple Goals Oriented Data Prefetching (MGODP) to satisfy the data prefetching requirements from different users. MGODP does not only take the user preferences into account to prefetch appropriate amounts of data, but also adopts global coordination for Client/Server data access model to greatly improve the quality of service from the server's perspective. Moreover, MGODP balances the workload between the mobile client and the backend server to achieve proper allocation of resources and to guarantee the system performance. Experimental results demonstrate that MGODP could satisfy diverse user requirements, and reduce the consumption of battery energy and network bandwidth through global coordination and workload balance. © by Institute of Software, the Chinese Academy of Sciences.
