Power-Aware Data Management for Mobil Devices

The popularity of mobile devices is growing rapidly. Due to the increase in application complexity, and the limited power supply in most mobile systems, energy optimization has become a popular research area. Different approaches have been used is lowering the energy cost. These include a variety of hardware and software techniques. In this research, we propose a novel technique that uses the smart caching approach cooperating with the direct memory access and the page caching mechanisms to keep process memory footprints small. More memory nodes thus can be put into a power-saving mode. As a result, the battery-powered supply of a mobile device can last longer. Experiments were conducted on a simulated operating system modified towards different energy-saving techniques. Analysis and comparisons were made to demonstrate the effectiveness of our approach
