Using typing pattern to save energy: Adaptive notification mechanism in MIM APPs

摘要

Typing notification of instant messaging APPs improves user experience during online chatting. However, frequent notification leads to high energy consumption of mobile devices. In this paper, we study the trade-off between the frequency of typing notifications for user experience and communication energy saving of mobile device. We propose adaptive typing notification mechanisms, which exploit user's typing pattern and the current network conditions to adjust notification intervals. Simulation results demonstrate the proposed schemes can significantly save energy while improving user experience.
