Embodiment

[0112] In order to verify the impact of the Wi-Fi power management strategy based on the importance of load on the power consumption and performance, the strategy was implemented on the Pandaboard development board and the actual measurement was carried out. The experimental results show that the bottom layer is guided by the division of the front and back data Wi-Fi-driven power consumption management can improve the response speed of the network for foreground applications, and the background process can reduce the energy consumption of wireless network cards when data transmission is performed.

[0113] 1. Experimental platform

[0114] The experiment uses the PandaboardES development board issued by Texas Instruments (Texas Instruments, TI) as the experimental platform. The development board is equipped with the mainstream configuration of current smartphones. It is one of the most popular experimental platforms for mobile platform developers. It is widely supported by various ...

Abstract

The invention discloses a method for lowering wifi power consumption based on data importance, characterized in that the method includes the following steps: (1) based on the sensitivity to network data of an application which requests the network data, assessing the application which requests the network data, and determining a delayed sensitivity level of the application; (2) based on the delayed sensitivity level of the application, via a corresponding wifi power consumption optimization scheme, configuring a wifi network interface card for controlling the transmission of the network data. The method herein can reduce tail part energy consumption of the network interface card. The delay in waking up the network interface card can increase the time when the network interface card is in sleep mode.

Description

Technical field [0001] The invention belongs to the technical field of wireless network card power consumption optimization, and specifically is a method for reducing wifi power consumption based on the importance of data. Background technique [0002] The ever-increasing number and power consumption have not only brought a heavy burden to the global power consumption, but more importantly, the ever-increasing computing power has reduced the standby time of smart phones, which has seriously affected the user experience of smart phones. Therefore, the power management technology of the smart phone platform has attracted the attention of more and more mobile phone manufacturers and researchers. Wireless network equipment is an important part of the energy consumption of smart phones. Especially in the sleep state, the screen energy consumption is reduced, and the wifi energy consumption becomes the main energy consumption. The present invention attempts to use a new idea to manage...
