Embodiment Construction
[0055] The technical solution of the present invention will be described in detail below with reference to the accompanying drawings and examples.
[0056] as attached figure 1 As shown, the system model of this embodiment is: there is a target in the network, as shown in the attached figure 1 As shown by the star in the middle; 10 sensor nodes are deployed in the network, as shown in the attached figure 1 As shown in the middle circle, the numbers are 1, 2, ..., 10. The attacker successfully captured the nodes numbered 1 to 3, making them malicious nodes, and the malicious nodes are as attached figure 1 Shown in the dotted circle. Nodes numbered 4 to 10 are normal nodes, as attached figure 1 Shown in solid circle. The power of the measurement noise at node i In this instance i=1,2,...,10. The distance d between node i and the target i And the distances are not equal to each other, in this example d 1 to d 10 1.5, 1.8, 2, 2.2, 2.5, 2.8, 3, 3.2, 3.6, 4 respectively...
