Abstract

This work proposes Group-based caching for Mobile Database Systems. In recent era, the usage of mobile devices becomes ubiquitous because of their salient features such as availability of data anywhere any time for various digital purposes. In addition to this, mobile devices are capable to store small amount of data in their cache memory upon system requirements. Hence, we can keep partial data on this cache to improve performance of mobile devices by means of reducing frequent network communication with the central servers such as database servers. Today's exponential growth in usage of mobile devices inspired us to develop group-based caching system for mobile database systems, widely known as mobile-databases. The main contributions of our work are three-folds. First, we propose Group-based caching model, designated as MobCache for mobile database systems. Second, we propose three different schemes for group-formation, namely Interest-based Grouping (IG), Density-based Grouping (DG) and Hybrid Grouping (HG). Third, we conduct performance study, which demonstrates that in order to retrieve data faster in mobile environment and to avoid large number of  connections to the server, mobile-caching is one of the important techniques.
