Mobile Network Transmission Key Technology Research For Energy Saving

With the dramatical development of the technologies of mobile device and network. Energy consumption caused by wireless data transmission takes a significant part of the overall energy consumption of mobile devices, due to the popularity of Internet applications. The core of the mobile network transmission key technologies for energy saving is the combination mobile terminal energy-saving technologies and mobile network technology. This research makes a great improvement on the power saving technology on mobile transmission.In order to carry out the research of the energy consumption of a transmitting mobile device, measurement is an essential component. Therefore, this paper presents an experimental platform of the energy consumption of transmitting mobile device. With the help of this platform, we may monitor the energy consumption and traffic records of mobile device while transmitting data and simulate a variety of network environments and scenarios. It has been proved that the accuracy of this platform is satisfactory and fits the demands of our future researches.In the next section we investigate the energy consumption characteristics of data transmission over Wi-Fi, focusing on the effect of Internet flow characteristics and network environment. We present power models that describe the power consumption with traffic burstiness, network performance metrics such as throughput and retransmission rate, and parameters of the power saving mechanisms in use. We demonstrate the practice of model-based energy profiling and evaluate the accuracy with physical power measurement of applications including file transfer and web browsing in different network environments. Our experimental results show that ourmodels are of adequate accuracy and are easy to apply.
