Analysis of Data Access Skewness in Mobile Systems

Abstract

When we observe data access behaviors in computing systems, the skewness can be found in any kind of system layers. In this article, we analyze the skewness of data accesses that appears in modern mobile computing systems. Specifically, we focus on three different layers based on our experiences. First, we show the access skewness in Web data and Web servers. Second, we show the skewness in file and storage accesses in a smartphone. Third, we show the skewness in smartphone memory accesses. We anticipate that the analysis result in this article will be helpful in the efficient design of mobile systems.
