Problems solved by technology

However, for the existing large-scale wireless sensor network detection environment, most of the cluster head nodes and the sink nodes are far away from each other and cannot communicate directly, so it is necessary to pass other cluster head nodes between the target cluster head node and the sink node. Carry out data transfer to finally realize the communication between the target cluster head node and the sink node

Embodiment 1

[0042] figure 1 It is a flow chart of a cluster head node routing method based on a wireless sensor network provided by an embodiment of the present invention. Please refer to figure 1 , the specific steps of the cluster head node routing method based on the wireless sensor network include:

[0043] Step S10: Obtain each feature value set of the target cluster head node.

[0044] Each eigenvalue set corresponds to the data transmission scenario of the target cluster head node, and the eigenvalue set at least includes the distance of the target communication path between the target cluster head node and the sink node.

[0045] It should be noted that the eigenvalues ​​in the eigenvalue set in this step can represent the status of a certain aspect of the target cluster head node communication, and each eigenvalue set should correspond to a target cluster head node and other clusters. The working scenario when the head node performs data communication, since the working scenar...

Embodiment 2

[0056] On the basis of the above embodiments, the present invention also provides the following preferred implementation modes.

[0057] As a preferred implementation manner, the feature value set also includes the remaining energy of the target cluster head node and the data traffic of the target cluster head node.

[0058] It can be understood that since the eigenvalue set represents the working scene of the target cluster head node, the more types of eigenvalues ​​in the eigenvalue set, the more detailed the working scene represented by the eigenvalue set. The remaining energy of the target cluster head node and the data communication volume of the target cluster head node are important factors that jointly affect the routing communication of the target cluster head node, so the remaining energy of the target cluster head node and the data communication volume of the target cluster head node are used as features The elements in the value set can make the calculation of the ...

Abstract

The invention discloses a cluster head node routing method and device based on a wireless sensor network, and a medium. The method comprises the following steps: acquiring each feature value set of atarget cluster head node; fitting a feature value in each feature value set and a power consumption gradient parameter as the power consumption prediction function according to a gradient descent algorithm; setting a power consumption threshold, and generating a loss function according to the power consumption prediction function and the power consumption threshold to balance the difference between the value of the power consumption prediction function and the power consumption threshold; computing the parameter value of the power consumption gradient parameter when the value of the loss function is minimum; performing the iterative operation of the parameter value on the basis of the preset power consumption gradient to obtain the result power consumption gradient, and taking the result power consumption gradient as the routing pointing of the target cluster head node. Through the method disclosed by the invention, the routing efficiency between the cluster head node and an aggregation node is improved. Furthermore, the invention further provides a cluster head node routing device based on the wireless sensor network and the medium with the above-mentioned advantages.

Description

technical field [0001] The invention relates to the field of wireless sensor networks, in particular to a cluster head node routing method, device and medium based on wireless sensor networks. Background technique [0002] A wireless sensor network is a wireless network composed of a group of sensor nodes in an adaptive and self-organizing manner. The wireless sensor network can be used for the collection, processing and transmission of real-time signals in special environments. Wireless sensor network is a new information acquisition and processing technology, which is being used more and more widely in real life. The wireless sensor network is formed by self-organization of tens of thousands of sensor nodes. The sensor nodes are powered by batteries. When the sensor nodes perform data collection, fusion and transmission operations, battery energy is required. Thousands of sensor nodes After being deployed, it is often not easy to replace, so it is necessary to ensure tha...
