Problems solved by technology

Since nodes often work in harsh environments and usually use batteries with limited energy to provide energy, this requires battery power supply time as long as possible. Once the power is exhausted, it means that the node loses its ability to work and needs to be removed from the network. Elim

Embodiment Construction

[0024] The present invention relates to a modeling and fault propagation method for a wireless network control system, the steps of which are as follows:

[0025] The first step is to select the BA scale-free network as the topology structure of the wireless network control system, determine the initial number of nodes and the growth scale of the network, and the number of newly generated edges each time a new node is introduced, so that the generated network structure has growth characteristics and Prioritize link features. Construct an adjacency matrix according to the connection relationship between network nodes, assuming that signals can be transmitted bidirectionally between connected nodes, that is, the network is an undirected propagation network, and the adjacency matrix constructed in this way is a symmetric matrix;

[0026] In the second step, for fixed-scale and variable-scale networks, according to the adjacency matrix, the average degree of the network changes wi...

Abstract

The invention discloses a method for modeling or fault propagation of a complex wireless network control system. A complex network viewpoint and method is used, a communication channel is used as a side, a model in which an edge and an edge weight describe a node connection relationship is established, the importance of a signal base station in the communication channel is described, and the network characteristics with a scale-free characteristic of the wireless network control system are presented. Meanwhile, a wireless network fault propagation method is discussed, and the parameters such as network fault levels, the size of node fault tolerance capacity and the number of initial fault nodes are changed to determine the influence of a wireless topology network parameter on cascade faults. The method for modeling or fault propagation of the complex wireless network control system provides a novel method and idea for modeling of the wireless network control system from the aspect of system engineering.

Description

[0001] technical field [0002] The invention relates to a modeling method of a network control system with a complex network topology in the field of computer simulation modeling, and provides a fault propagation method based on the model, which is suitable for modeling network control systems and network faults Spread the diagnosis. Background technique [0003] According to different transmission media, the network control system can be divided into wired network control system and wireless network control system. Due to the convenience of application, networking and maintenance of wireless network, the application of wireless network is becoming more and more extensive, resulting in the emergence of A control system that communicates based on wireless channels, that is, a wireless network control system. The use of wireless networks for communication can eliminate a large number of line connections, save system construction costs and maintenance costs, and can also meet...
