Problems solved by technology

The energy balance method based on social nature uses the betweenness centrality and similarity of nodes to forward messages. Nodes continuously forward messages to nodes with high power values. Nodes with high power values ​​consume too much energy, which seriously affects the transmission network. transmission performance
[0004] In summary, the existing energy balance method will lead to message transmission delay and transmission performance reduction of the transmission network

Embodiment 1

[0034] figure 1 A schematic flowchart of a message transmission method provided in Embodiment 1, such as figure 1 As shown, the method includes the following steps:

[0035] Step 101, the message carrying node judges whether the remaining energy identifier of the encountered node is a preset value, if yes, execute step 102; if not, continue to execute step 101.

[0036] Step 102, the message carrying node judges whether the ratio of the energy consumption rate of the encountered node to the energy consumption rate of the message carrying node is less than or equal to a preset ratio, if yes, execute step 103; if not, execute step 101.

[0037] Step 103, the message carrying node judges whether the utility function of the message carrying node is smaller than the utility function of the meeting node, if yes, execute step 104; if not, execute step 101.

[0038] Step 104, the message carrying node allocates a copy of the carried message to the meeting node according to the remai...

Embodiment 2

[0041] figure 2 A schematic flowchart of a message transmission method provided in Embodiment 2, such as figure 2 As shown, the method includes the following steps:

[0042] Step 201, the message carrying node judges whether the remaining energy identifier of the encountered node is a preset value, if yes, execute step 202; if not, continue to execute step 201.

[0043]Preferably, the message transmission method in this embodiment is based on the Internet of Things network. The Internet of Things network includes a plurality of nodes, and the plurality of nodes are randomly deployed. The message carrying nodes carry messages, and the message carrying nodes transmit the carried messages through multiple nodes in the Internet of Things network.

[0044] The remaining energy identification is used to indicate whether the meeting node has enough remaining energy to transmit the message, and the remaining energy identification is passed through the formula Calculated, where S...

Embodiment 3

[0063] image 3 A schematic structural diagram of a message transmission system provided by Embodiment 3 of the present invention, as shown in image 3 As shown, the message transmission system includes a message carrying node 11 and an encounter node 12 .

[0064] The message carrying node 11 is used to judge whether the remaining energy identifier of the meeting node 12 is a preset value, and if it is judged that the remaining energy identifier of the meeting node 12 is a preset value, judge the energy consumption rate of the meeting node 12 and whether the ratio of the energy consumption rate of the message carrying node 11 is less than or equal to the preset ratio, if it is judged that the ratio of the energy consumption rate of the encounter node 12 to the energy consumption rate of the message carrying node 11 is less than or equal to the preset ratio When setting the ratio, judge whether the power function of the message carrying node 11 is less than the power function...

Abstract

The present invention discloses a message transmission method and system. The method comprises the steps of: distributing copies carrying messages to an encountering node according to a message carrying node and the rest energy value of the encountering node if the message carrying node determines that the rest energy identifier of the encountering node is a preset value, the ratio of the energy consumption rate of the encountering node and the energy consumption rate of the message carrying node is smaller than or equal to a preset ratio and an effect function of the message carrying node issmaller than an effect function of the encountering node. The message transmission method and system can effectively avoid delay of the message transmission so as to improve the transmission performance of the transmission network.

Description

technical field [0001] The present invention relates to the technical field of wireless networks, in particular to a message transmission method and system. Background technique [0002] In wireless sensor networks, the source node needs multiple intermediate nodes to forward data to the destination node beyond the communication distance. In order to realize the normal transmission of data, there must be at least one complete data transmission path between the source node and the destination node. In the actual application environment, the movement and data transmission of nodes need to be powered by batteries, which makes the energy, bandwidth and cache space of nodes very limited. If the energy of a certain node is consumed too much, the energy of the nodes in the wireless sensor network will be unbalanced, which may lead to data transmission failure. [0003] Currently commonly used energy balance methods include: probability-based energy balance methods and social-base...
