Research On Power Management And Energy Consumption Optimization For Mobile Terminal

With the development of technology,the development trend of high-tech war is inevitable.Tactical mobile terminals play more and more important roles in the war because of the requirements of the military field.The terminals are equipped with highperformance hardware,such as CPU,multifunctional cameras and sensors to improve military force and meet the various of the military field.These designs bring a severe test to the battery life.This thesis focuses on the power management in YROS.We discuss the power management in Linux and Android.There are three technologies are proposed to solve problems of YROS: lacking supervision of applications’ consumption and power management for mobile terminals.1.A power consumption statistical model is designed which is only related to the terminal device components.The technology allows remodeling if the devices are equipped with different components.2.We prioritize the applications and satisfy user’s experience because applications can be free to use the resources.Different priorities have different polices so the components will be closed or idle during a long time.The policies dictate how long and how often the applications can use resources.3.In idle mode,the components’ state can cause power consumption.In order to manage Wi-Fi intelligently,a power optimization technology based on context-aware information is proposed.We analyze the context-aware information to determine the state of Wi-Fi.We process complex context-aware information and use within-cluster and between-cluster scatter to select context-aware attributes.Decision algorithm is based on SOM.Finally,we do experiments based on YROS mobile devices for the tree proposed technologies.The results show that power consumption statical model can calculate power and other technologies can save power.
