Abstract

Most mobile applications need to download data from the network. The Android system temporarily stores these data as cache ﬁles in the local ﬂash storage to improve their re-access performance. For example, using Facebook for two hours in one case generated 1.2GB cache ﬁles. Writing all cache ﬁles to the ﬂash storage has a negative impact on the overall I/O performance and deteriorates the lifetime of mobile ﬂash storage. In this paper, we analyze the access characteristics of cache ﬁles of typical mobile applications. Our observations reveal that the access patterns of caches ﬁles are different from application-level to ﬁle-level. While existing solutions treat all cache ﬁles equally, this paper differentiates cache ﬁles into three categories, burn-after-reading, transient, and long-living. A Fine-grain Cache File Management (FCFM) framework is proposed to manage different cache ﬁles differently to improve the performance and lifetime of the mobile system. Evaluations using YouTube show that FCFM can signiﬁcantly improve the performance and lifetime of mobile devices.
