Problems solved by technology

Although the cascading failure model of complex networks has made some achievements, its application in military command and control networks is still in its infancy
If the above cascading failure model is directly applied to the command and control network, there are mainly the following problems: First, there are a large number of edge nodes in the command and control network, and the degree value or betweenness value of these nodes is a fixed value, and the traditional method definition can

Embodiment 1

[0061] A method for constructing a command and control network cascading failure model based on node importance, the specific steps are as follows:

[0062] S1: Define the initial load of the node, specifically: for the existing cascading failure model, only the importance of the node itself is considered, and the contribution of neighboring nodes is not considered, which makes the initial load definition accuracy low and affects the cascading invulnerability of the network Problem, the present invention proposes an initial load definition method based on the contribution degree of m-order neighbor nodes.

[0063] According to the theory of spatial autocorrelation, in a complex network, the closer the distance between node pairs, the greater the importance contribution to each other; the farther the distance between node pairs, the smaller the importance contribution to each other. These importance contributions also decay exponentially with distance. As a typical military ne...

Embodiment 2

[0100] This embodiment is as the supplement of embodiment 1:

[0101] Based on the established command and control network cascading failure model, the optimal model parameters are determined. Specifically: using the idea of ​​the control variable method to adjust each parameter in the cascading failure model, and then carry out a deliberate attack on the accusation network. The performance index measures the impact of model parameter values ​​on the command and control network, and then determines the optimal parameters of the model, so that the command and control network has the strongest ability to resist cascading failures.

[0102] image 3 is the simulation graph of the curve of node importance changing with parameter μ. In order to verify that the node importance method of the present invention is more superior, by adjusting different parameters μ, the node importance change curve is as follows image 3 As shown, μ∈{0.6,0.7,0.8,0.9,1.0}. According to the weight coe...

Abstract

The invention discloses a command and control network cascading failure model construction method based on node importance. The cascading failure resistance of a command and control network can be remarkably improved by reasonably adjusting corresponding parameters in a model, and the cascading destruction resistance of the command and control network is optimal due to the existence of optimal model parameters. According to the OODA combat theory and in combination with the concept of combat link betweenness, a new initial load definition method, a nonlinear load capacity model and a load redistribution strategy are given, and the internal mechanism and the external behavior of command and control network cascade failure can be reflected more effectively and accurately.

Description

technical field [0001] The invention belongs to the field of military command and control, and relates to the establishment of a command and control network cascade failure model, specifically a command and control network cascade failure model based on node importance. Background technique [0002] The command and control network, as the hub of command and control system order issuance and information transmission, is the key to victory in war. With the continuous improvement of battlefield informatization, the organizational structure of the command and control network is becoming more and more complex, and information interaction is more frequent, showing the characteristics of diverse and heterogeneous nodes and multiple interlaced links, which have typical complex network characteristics. At the same time, the command and control network is also the primary target of enemy attacks, and destroying the command and control network destroys the heart of the combat system. ...
