A Model for Optimizing Data Caching of Dual Mode Handheld Devices
Handheld apparatus are widely used especially when equipped with an automatic data capturing solutions. They are usually connected to the main database server using either an economic fixed location mode or a more expensive mobile mode. In order to quantify the gap of the two modes, a metric called mobility coefficient is introduced. Then, a mathematical model is developed to optimize the handheld data caching. This model considers several factors affect the cache performance such as the data item size, its access frequency, its update rate, the cache size, and the caching cost. Finally, a series of simulation experiments are conducted in order to validate of the proposed model under various system configurations.
