Reliability analysis of"Air-Communication-Ground"formation based on interdependent failure
A reliability analysis algorithm for Aerial-Communication-Ground cluster formation based on the operational rules of multi domain unmanned platforms and the failure relationship of logical connections between layer networks is proposed to address the difficulty in analyzing the reliability of large-scale multi domain unmanned equipment.A three-layer lightweight grid topology structure composed of aerial network,communication network,and ground network is used to replace clusters in the real world.Under the conditions of considering random attacks,intentional attacks,regional failure relationships,correlation failure relationships,and cascade failure relationships,the algorithm is designed to measure reliability based on the largest connected subgraph in the network,and to analyze network reliability under different formation states and formation forms.Finally,a comparison was made with the standard simulation platform,and the experimental results verified the feasibility,speed,and low resource utilization of the algorithm.This study provides a research foundation for improving the reliability and related prevention and control strategies of collaborative formation of multi domain unmanned platforms.
