A Wi-Fi mobile networking method with balanced energy consumption

technical field

The invention relates to the field of Wi-Fi application technology, in particular to a Wi-Fi mobile networking method with balanced energy consumption.

Background technique

Nowadays, smart phones are becoming more and more popular due to their increasingly powerful computing power, so that they can also be used as an intelligent mobile Internet terminal, and their expanded functions have already surpassed people's imagination.

Wi-Fi technology is a technology that can connect terminals such as personal computers, mobile phones, and iPADs wirelessly. With the maturity and wide application of Wi-Fi technology, almost all mobile devices now have the function of Wi-Fi connection, and almost all mobile devices support the function of opening AP hotspots based on Wi-Fi technology. Through the aforementioned Wi-Fi technology, a small wireless local area network composed of a large number of mobile devices can be used for communication.

Mobile devices are easy to carry and flexible to use. However, it is usually difficult for mobile devices to be charged by a fixed power source, and the mobile power source has limited power. When a mobile device serving as an AP hotspot is short of power, the communication between the nodes of the existing small mobile local area network will be disconnected, and it needs to be reset. During this process, the data of the transmitted file is either lost or needs to be retransmitted after the communication is restarted, which brings a lot of inconvenience to the user, especially when the file is large.

Contents of the invention

In order to solve the above problems, the present invention provides a Wi-Fi mobile networking method with balanced energy consumption, which can automatically switch the AP function to other devices in the local area network when the power of the mobile device as the AP hotspot is lower than the balanced power. Node, to ensure that the energy consumption of the established network is balanced, the data transmitted by the file will not be lost during the switching process, and the switching process is completely transparent to the user.

Its technical solution is as follows: a Wi-Fi mobile networking method with balanced energy consumption, characterized in that it includes the following steps:

(1) Select at least two mobile devices with Wi-Fi connection, AP hotspot and data processing functions;

(2) Make one of the mobile devices turn on the AP hotspot mode, and the other mobile devices connect to the mobile device with the AP hotspot mode turned on through Wi-Fi to form a Wi-Fi mobile local area network;

(3) When transferring files in the mobile local area network, the mobile device receiving the file is equipped with an ID number for each file being received and creates a corresponding log file, and writes it to the After the file, update the corresponding log file and record the number of bytes received;

(4) Mobile devices with AP hotspot mode enabled regularly collect the percentage of remaining battery power and power consumption per unit time of each mobile device, and select the most suitable mobile device for enabling AP hotspot mode based on the unit power consumption rate of each mobile device. equipment;

(5) If the mobile device that is most suitable for enabling the AP hotspot mode is a mobile device that has already enabled the AP hotspot mode, the existing network will continue its connection mode and status; if the mobile device that is most suitable for enabling the AP hotspot mode is not already enabled for the AP hotspot mode, the mobile device that has turned on the AP hotspot mode sends an AP hotspot switching signal to the mobile device that is most suitable for turning on the AP hotspot mode, and closes its own AP hotspot mode, opens the Wi-Fi connection, and optimally turns on the AP hotspot mode Close the Wi-Fi connection of the mobile device and enable the AP hotspot mode, and the other mobile devices connect to the mobile device with the newly enabled AP hotspot mode through Wi-Fi, and re-establish the Wi-Fi network; after the Wi-Fi network is rebuilt, each device Created log files, continue data transmission from the point where data transmission is interrupted, and maintain the normal operation of the network.

It is further characterized in that the Wi-Fi connection between mobile devices in the mobile network uses a fixed SSID and password, and is set to be invisible to other devices.

After using the solution of the present invention, after the mobile device is connected to the mobile device with the AP hotspot mode enabled through Wi-Fi to form a mobile network, the remaining battery power percentage and the power consumption per unit time of each mobile device are collected regularly, based on the analysis of each mobile device Based on the calculation results of the energy consumption rate, the mobile device with the best AP hotspot mode enabled is selected, and the mobile device is automatically selected to enable the AP hotspot mode, so that the AP function can be automatically switched when the power of the mobile device serving as the AP hotspot is lower than the balance power.
