| The multi-functionality and complexity of modern mobile systems have brought a challenge to guarantee a user desired battery lifetime. Power management (PM) schemes that specifically manage energy as the first-class resource have been proposed to achieve the lifetime goal. However, it is still an open question on designing the scheduler to be energy-aware and deadline-aware. This paper presents the energy-based fair queuing (EFQ) scheduling, a novel energy-aware scheduling algorithm that supports the proportional energy use, effective time-constraint meeting and a flexible tradeoff between them. The proposed algorithm is implemented in the Linux kernel V3.3 and its properties are verified in a test-bench based on an open source Linux scheduler simulator with user specified energy loads. A comparative simulation with the default Linux scheduler shows that EFQ is more effective in avoiding energy starvation and maintaining the user-perceived performance. | |
