Abstract

Smartphones are facing a grand challenge in extending their battery life to sustain an increasing level of processing demand while subject to miniaturized form factor. Dynamic Voltage Scaling (DVS) has emerged as a critical technique to leverage power management by lowering the supply voltage and frequency of processors. In this paper, based on the DVS technique, we propose a novel Energy-aware Dynamic Task Scheduling (EDTS) algorithm to minimize total energy consumption for smartphones while satisfying stringent time constraints for applications. This algorithm utilizes the results from a static scheduling algorithm and aggressively reduces energy consumptions on the fly. Experimental results indicate that the EDTS algorithm can significantly reduce energy consumption for smartphones, compared to the critical path scheduling method and the parallelism-based scheduling algorithm.
