Abstract EN
Video streaming service is one of the most popular applications for mobile users.
However, mobile video streaming services consume a lot of energy, resulting in a reduced battery life.
This is a critical problem that results in a degraded user’s quality of experience (QoE).
Therefore, in this paper, a joint optimization scheme that controls both the central processing unit (CPU) and wireless networking of the video streaming process for improved energy efficiency on mobile devices is proposed.
For this purpose, the energy consumption of the network interface and CPU is analyzed, and based on the energy consumption profile a joint optimization problem is formulated to maximize the energy efficiency of the mobile device.
The proposed algorithm adaptively adjusts the number of chunks to be downloaded and decoded in each packet.
Simulation results show that the proposed algorithm can effectively improve the energy efficiency when compared with the existing algorithms.
