Referring to fig. 3, fig. 3 is a flowchart illustrating a data transmission method according to another embodiment of the present invention.

Referring to fig. 4, fig. 4 is a schematic flowchart of a data transmission method according to another embodiment of the present invention.
As shown in fig. 4, before step S400, the method further includes:
step S500: performing a clustering test on each forwarding node transmitting target data to monitor clustering information of each forwarding node to obtain a clustering information monitoring result;
step S600: acquiring a central node in all forwarding nodes according to the monitoring result;
step S700: determining the network distribution amount of each forwarding node except the central node during target data transmission according to the position information between each forwarding node except the central node and the central node;
step S800: determining the skip information between every two forwarding nodes according to the distribution quantity of each network;
step S900: and selecting the path with the maximum transmission power as a transmission path according to all the jumping information.
In this embodiment, it can be understood that a plurality of forwarding nodes transmit the target data, and the efficiency of transmitting the target data is different when the selected forwarding nodes are different.
For example, there are five forwarding nodes in total, the five forwarding nodes are subjected to a clustering test, and in the test process, clustering information of each forwarding node is monitored. The monitoring result shows that the first forwarding node can respectively receive the clustered information sent by the other four forwarding nodes, and then the first forwarding node is determined as the central node.
It will be appreciated that the location information between each forwarding node and the central node may or may not be the same. Therefore, the network allocation amount of each forwarding node is determined according to the position information between each forwarding node and the central node.
Specifically, the first forwarding node is closest to the central node, and the fifth forwarding node is farthest from the central node. Therefore, the network allocation amount of the first forwarding node is the largest, and the network allocation amount of the fifth forwarding node is the smallest.
For example: according to the position information of the four forwarding nodes and the center, the network allocation quantity of the second forwarding node is larger than the network allocation quantity of the third forwarding node, larger than the network allocation quantity of the fourth forwarding node, and larger than the network allocation quantity of the fifth forwarding node. It will be appreciated that the greater the network allocation, the less time is required to transmit the data. Therefore, the second forwarding node jumps to the third forwarding node faster than the second forwarding node jumps to the fourth forwarding node, and the efficiency is higher. Then, a path formed by the second forwarding node, the first forwarding node, and the third forwarding node is selected as a transmission path for transmitting the first target data.
By the technical scheme provided by the embodiment, the clustering information of each forwarding node for transmitting the target data is monitored to obtain the central node, the network allocation amount of each forwarding node except the central node during target data transmission is determined by acquiring the position information of each forwarding node except the central node and the central node, the jump information between every two forwarding nodes is determined according to the network allocation amount, and after all the jump information is compared, the path with the largest transmission power is selected as the transmission path during target data transmission.
Referring to fig. 5, fig. 5 is a schematic flowchart illustrating a data transmission method according to another embodiment of the present invention.
As shown in fig. 5, step S400 specifically includes:
step S410: counting the frequency of each device for sending initial data;
step S420: determining the weight information of the equipment corresponding to each target data according to the total frequency of all the equipment for sending the initial data;
step S430: acquiring flow consumption information when each target data is transmitted;
step S440: determining a transmission grade corresponding to each target datum according to the formula 1, wherein the formula 1 is as follows:
Di＝Qi×q+(1-Li)×l
di is the transmission grade of the target data corresponding to the ith device, and QiWeight corresponding to the weight information of the ith device is represented, q represents a proportionality coefficient occupied by the weight in a preset transmission mechanism, and LiRepresenting traffic consumption for transmitting target data of ith deviceThe information corresponds to the flow consumption level, and l represents a proportional coefficient occupied by the flow consumption level in a preset transmission mechanism;
step S450: and transmitting all the target data in the transmission queue on the transmission path according to the transmission grade corresponding to each target data.
In this embodiment, it can be understood that frequencies of sending the initial data by each device are different, so that the weight information of the device corresponding to each target data is obtained according to the frequency of sending the initial data by each device, and the traffic consumption information when each target data is transmitted is obtained. Each target data has different transmission levels, and the transmission level corresponding to each target data is determined according to the weight information and the flow consumption information of each target data. And transmitting different target data corresponding to different transmission grades on the transmission path according to the difference of the transmission grades.
For example: first weight information of the first device corresponding to the first target data is obtained. Wherein the first weight information includes: the importance level of the first device among all devices and the frequency with which the first device transmits the first target data.
First traffic consumption information at the time of transmitting first target data is acquired.
A transmission level of the first target data is determined based on the first weight information and the first traffic information. It can be understood that, the higher the importance level of the first device is, the higher the frequency of sending the first target data is, the higher the transmission level corresponding to the first target data is, and the first target data is transmitted preferentially.
Specifically, in the transmission queue, there are two pieces of target data, which are the first target data and the second target data, respectively. The first target data corresponds to a first device and the second target data corresponds to a second device. And if the importance level of the first equipment is higher than that of the second equipment, the first target data is transmitted preferentially.
For example, the weight of the first device is 70 as known by the frequency with which the first device transmits the initial data. As can be seen from the traffic consumption information of the target data transmitted from the first device, the traffic consumption level of the first device is 30%. And the proportion coefficient occupied by the preset weight is 0.6, and the proportion coefficient occupied by the preset flow consumption level is 0.4, then the transmission level of the first device is 42.28 through the calculation of the formula 1.
And the weight of the second device is 80, as known by the frequency with which the second device transmits the initial data. And, as can be seen from the traffic consumption information of the target data transmitted from the second device, the traffic consumption level of the second device is 40%. The coefficient of proportionality occupied by the preset weight is 0.6, and the coefficient of proportionality occupied by the preset flow consumption level is 0.4, then the transmission level of the second device is 48.24 by calculating according to equation 1.
That is, since the transfer level of the target data corresponding to the first device is higher than the transfer level of the target data corresponding to the second device, the target data corresponding to the first device is transferred preferentially when the target data is transferred.
According to the technical scheme provided by the embodiment, the transmission grade corresponding to each target data is determined according to the weight information and the flow consumption information of each target data, so that the technical scheme that all target data are transmitted according to the transmission grade corresponding to each target data is realized, and on one hand, the technical defect that data transmission congestion is easily caused by the fact that received data are directly transmitted when the data are transmitted in the prior art is avoided; on the other hand, the technical disadvantage that the burden of the system is increased when a plurality of data are transmitted simultaneously is avoided. The technical effect of orderly transmitting the data is realized. The data transmission method and the data transmission device have the advantages that the data can be transmitted quickly and efficiently, the load of a system is reduced, the burden of the system is reduced, the consumption is reduced, and the resources are saved.
Referring to fig. 6, fig. 6 is a flowchart illustrating a data transmission method according to another embodiment of the present invention.
As shown in fig. 6, step S400 specifically includes:
step S460: acquiring a transmission parameter of each target data;
step S470: comparing each transmission parameter with a preset threshold value to obtain at least one transmission parameter difference value;
step S480: and transmitting all target data in the transmission queue on the transmission path according to the obtained difference values of all transmission parameters.
In this embodiment, it can be understood that, since each target data has its own characteristic, when different target data are transmitted, the transmission parameters corresponding to different target data are not the same.
For example: there are three target data, which are the first target data, the second target data, and the third target data, respectively. The first target data corresponds to a first transmission parameter, the second target data corresponds to a second transmission parameter, and the third target data corresponds to a third transmission parameter.
And comparing the first transmission parameter, the second transmission parameter and the third transmission parameter with a preset threshold respectively, namely obtaining the difference between the first transmission parameter and the threshold, the difference between the second transmission parameter and the threshold and the difference between the third transmission parameter and the threshold respectively to obtain three transmission parameter difference values. And transmitting the three target data according to the difference values of the three transmission parameters.
According to the technical scheme provided by the embodiment, the transmission parameter of each data is compared with the preset threshold value to obtain at least one transmission parameter difference value, so that all target data are transmitted according to all the transmission parameter difference values. The following steps are implemented for all target data: the data transmission method has the advantages that regular transmission is carried out regularly, the technical defects of crowding and resource consumption in the transmission process are avoided, and therefore the technical effect of quickly and efficiently transmitting the target data is achieved.
Referring to fig. 7, fig. 7 is a flowchart illustrating a data transmission method according to another embodiment of the present invention.
As shown in fig. 7, step S480 specifically includes:
step S481: if the transmission parameter difference is greater than 0, adding the target data corresponding to the transmission parameter difference greater than 0 into the first set;
step S482: if the transmission parameter difference is smaller than 0, adding the target data corresponding to the transmission parameter difference smaller than 0 into a second set;
step S483: arranging the target data in the first set and the second set according to the sequence that the difference value of the transmission parameters corresponding to each target data is from small to large;
step S484: and sequentially transmitting the target data in the second set after arrangement and the target data in the first set after arrangement on a transmission path.
Specifically, the arranged target data in the second set is transmitted on the transmission path, and then the target data in the first set is transmitted on the transmission path.
In this embodiment, all the target data are classified according to the transmission parameter difference. The difference value of the transmission parameters is larger than 0, namely, the target data of which the transmission parameters are larger than the threshold value are classified into a first class, and the data of the first class are classified into a first set. And dividing the target data with the transmission parameter smaller than the threshold into a second class and dividing the data of the second class into a second set, wherein the difference of the transmission parameters is smaller than 0.
In the first set, each target data is arranged according to the sequence from small to large of the transmission parameter difference value corresponding to each target data. Similarly, each target data in the second set is also arranged. And sequentially transmitting the target data in the second set after arrangement, and sequentially transmitting the target data in the first set after arrangement.
Specifically, there are six target data (from the first target data to the sixth target data) corresponding to six transmission parameter differences (from the first transmission parameter difference to the sixth transmission parameter difference).
And if the difference value from the first transmission parameter difference value to the third transmission parameter difference value is greater than 0, adding the first target data to the third target data into the first set.
