摘要

Since mobile computers have limited resources, not many jobs are processed simultaneously. Then the overhead of context switching among the processes becomes relatively more significant. In this paper, we propose a dynamic process scheduling scheme for mobile computers, which adjusts the size of time slice of round robin scheduling depending on the number of processes in order to reduce the number of context switching. Experiment with Linux verifies that cache miss rate decreases as the time slice increases, and the proposed scheduling scheme significantly improves turnaround time compared to the scheduling scheme adopted in Linux.
