Enhancing init scheme for improving bootup time in mobile devices

Abstract

The init process has evolved as a system and service manager of process scheduling, input/output scheduling, memory scheduling, and the creation and termination of processes. The addition of software functionality increases software complexity. In a mobile environment, the increase of software complexity results in a slow boot time for mobile devices. This paper describes a mobile aware bootup framework by isolating the dependencies of the execution sequence among the processes, and by simplifying the existing init scheme to accelerate the boot time of the mobile device. From our experiment, our proposed approaches reduce the bootup time of the mobile device by about 50%.
