| Summary: | Online video streaming is getting more common in the smartphone device nowadays.
Since the Corona Virus (COVID-19) pandemic hit all human across the globe in 2020,
the usage of online streaming among smartphone user are getting more vital.
Nevertheless, video streaming can cause the smartphone energy to drain quickly
without user to realize it. Also, saving energy alone is not the most significant issues
especially if with the lack of attention on the user Quality of Experience (QoE). A
smartphones energy management is crucial to overcome both of these issues. Thus, a
QoE Mobile Video Selection (QMVS) framework is proposed. The QMVS
framework will govern the tradeoff between energy efficiency and user QoE in the
smartphone device. In QMVS, video streaming will be using Dynamic Video Attribute
Pre-Scheduling (DVAP) algorithm to determine the energy efficiency in smartphone
devices. This process manages the video attribute such as brightness, resolution, and
frame rate by turning to Video Content Selection (VCS). DVAP is handling a set of
rule in the Rule Post-Pruning (RPP) method to remove an unused node in list tree of
VCS. Next, QoE subjective method is used to obtain the Mean Opinion Score (MOS)
of users from a survey experiment on QoE. After both experiment results (MOS and
energy) are established, the linear regression technique is used to find the relationship
between energy consumption and user QoE (MOS). The last process is to analyze the
relationship of VCS results by comparing the DVAP to other recent video streaming
applications available. Summary of experimental results demonstrate the significant
reduction of 10% to 20% energy consumption along with considerable acceptance of
user QoE. The VCS outcomes are essential to help users and developer deciding which
suitable video streaming format that can satisfy energy consumption and user QoE. |
