Embodiment Construction
[0063] The present invention will be further described below in conjunction with accompanying drawing:
[0064] refer to figure 1 , the usage scenario of the present invention is:
[0065] In this scene, there are 36 undifferentiated ordinary nodes and a sink node, and all ordinary nodes except the sink node carry the same initial energy. 36 ordinary nodes are randomly distributed in the rectangular area drawn by the solid line, and the Sink node is located in the center of the area. figure 1 The middle gray circle represents the Sink node, figure 1 A white circle with a label in represents a normal node.
[0066] refer to figure 2 , the present invention aims at figure 1 The implementation steps of wireless sensor network clustering in the scenario are as follows:
[0067] Step 1, create an initialization cluster.
[0068] (1a) Initialize the trust evaluation value record stored by the Sink node, that is, Figure 4 TR, N, T in are initialized to 0.5, 0, 0 respectivel...
