(English Abstract)
Smartphones on Android platform recently have been come into wide use. However, it is often reported that Android smartphones cannot provide enough interactivity because Android cannot distinguish interactive tasks and non-interactive tasks and they are scheduled with the same priority and preempted. Thus, it occurs poor response time. This paper proposes a framework assisted priority boosting and load balancing for improving interactivity of Android smartphones. The framework assisted priority boosting technique distinguishes the interactive task in the framework level and send the task ID to the kernel. The kernel ensures enough time to process user input by boosting the priority of distinguished task. The load balancing technique minimizes response time of boosted task by migrating tasks disturbing boosted task to other run-queue. The experiment results demonstrate the priority boosting technique reduces response time up to 22% and the load balancing technique along with priority boosting reduces response time up to 43.31% compared to the previous techniques.
