Problems solved by technology

[0005] In such cases, each node user needs to download the same data segment, which not only increases the burden on the server of the download site, but also relatively wastes energy due to repeated downloading of data

Embodiment 2

[0110] 3 node workstations, the table shows the total energy consumption data, including the base station AP and all workstations Sta:

[0111] Table 2 Embodiment 2 uses the traditional method and the comparison of the power consumption of the method of the present invention Unit: Joule

[0112] Amount of downloaded data (Mb)

[0113] It can be seen from the experimental results that the present invention can reduce the energy consumption of downloading. The reduced power consumption increases with the download node and the download data volume. In particular, when there are 20 nodes downloading 3MB of data, the energy saving reaches 1696.92 Joules. When 3 nodes download 20MB of data, the energy saving reaches 716.532 joules.

Abstract

A heterogeneous network download energy-saving method based on residual energy comprises the following steps that firstly, it is set that handheld equipment can make use of a network A and a network B at the same time, and all the equipment can be directly connected into a set through the network B; data are transmitted outside through the network A, communication is conducted inside through the network B, and the data are distributed; when all nodes intend to download the same piece of data from the outside, the whole set will divide the task into smaller parts according to different residual electric quantities of all the nodes, the smaller parts are allocated to the nodes respectively, and each node downloads the data through the network A and then sends the data to other nodes through the network B. By the adoption of the heterogeneous network download energy-saving method, data transmission of the networks can be combined, and energy consumption of the equipment for obtaining the same piece of data is optimized.

Description

technical field [0001] The invention relates to the field of network communication. Specifically, it is an energy-saving method for heterogeneous network downloading based on residual energy. Background technique [0002] Today's handheld devices are equipped with more than one communication module, such as mobile phones, which generally have 3G, GPRS, wifi, bluetooth, etc. However, the high energy consumption per unit data transmission of 3G and GPRS conflicts with the limited energy of mobile phones. In addition, compared with 3G and GPRS, wifi and bluetooth have high speed, low energy consumption per unit data transmission, but short transmission distance. [0003] According to the previous method, such as figure 1 , DEVICE NODE 1 ,NODE 2 ,NODE 3 ......To get the same piece of data W, then NODE 1 ,NODE 2 ,NODE 3 ...will download data W via 3G or GPRS respectively. This way of downloading is repeated, and no bluetooth or wifi is used during this period, even thou...
