- Nowadays mobile data traffic is soaring gradually year by year, the total monthly mobile data traffic (includes uplink and downlink) has come to more than 3,500 Petabytes and the growing trend is continuing. Video streaming demand is the significant contributor of cellular network data traffic, it accounted for more than 45% of mobile data traffic, and the occupancy percentage also is increasing. However the online video playing on mobile devices is still limited by battery technology which does not keep up with the development of cellular networks and mobile processor, mobile users may always need to charge the battery avoiding from device shutting down without power. Currently researchers focus on how to decrease mobile power consumption to prolong the battery lifetime and free mobile devices from charging cables. So it is urgent to understand and decrease the mobile power consumption of online video streaming in LTE networks. In this paper, we conduct a series of experiments to make a deep study of video streaming energy performance characteristics. We design some scenarios for collecting useful mobile power performance data and also measure the state-of-the-art video streaming performance and power consumption. We propose a client-side method to save the power consumption of mobile devices while the video streaming service is using. This method allows multiple video segments can be appended to the video player buffer each time. According to our experimental statistics, the mobile device can save up to more than 30% of the total power consumption for network part by using our multi-appending scheme for online video streaming.
