Embodiment

[0047] This embodiment proposes a wireless sensor cluster routing cluster head selection method applied to the electric power Internet of Things.

[0048] The method of the present embodiment mainly consists of four stages:

[0049] (1) Inter-node communication test phase, in which nodes send test data packets to each other to calculate the energy efficiency value of inter-node communication, and establish a neighborhood node information table;

[0050] (2) During the competition stage of cluster head nodes, the whole network selects the node with the maximum communication energy efficiency value of the neighborhood nodes as the cluster head node, and the cluster head node broadcasts its own neighborhood node parameter list to the whole network;

[0051] (3) In the iterative stage of the algorithm, the cluster head node sets the attenuation coefficient for the neighbor nodes and enters the dormant state, and each node in the whole network recalculates the sum of the communicatio...

Abstract

The invention discloses a wireless sensing clustering routing cluster head selection method applied to power Internet of Things. The method comprises the following steps that: 1, nodes mutually send test data packets therebetween to calculate a communication energy efficiency value between the nodes, and establish a neighborhood node information table; 2, nodes with the maximum sum of communication energy efficiency values of neighborhood nodes are selected as cluster head nodes in the whole network; 3, the cluster head nodes set attenuation coefficients for the neighborhood nodes and then enter a dormant state, all the nodes of the whole network recalculate the sum of the communication efficiency of the neighborhood nodes, and the step 2 is executed till a preset number of cluster head nodes are obtained; and 4, each non-cluster head node selects the cluster head node with the highest path efficiency value as the cluster head of the non-cluster head node according to the cluster head information table to carry out data transmission. According to the wireless sensing clustering routing cluster head selection method, the node with the highest communication energy efficiency is automatically selected as the cluster head of the whole network, and data transmission is carried out between each node and the cluster head node according to the path with the highest communication energy efficiency.

Description

technical field [0001] The invention belongs to the technical field of Internet of Things data transmission, and in particular relates to a method for selecting a wireless sensing cluster routing cluster head applied to the Internet of Things. Background technique [0002] With the continuous development of wireless communication and sensing technology, various sensor networks interconnected with things are gradually entering people's daily life. Through wireless communication technology, traditional electrical equipment and various distributed power generation devices can be flexibly interconnected and exchange monitoring data with the base station. Traditional wireless sensor networks use clustering routing algorithm for data transmission, which mainly considers the remaining energy of network nodes and data transmission costs and other indicators, and maximizes the network life cycle as the optimization goal. However, for the power Internet of Things, the monitoring data...
