摘要
针对大规模多域无人设备之间难以进行可靠性分析的问题,根据实际"空-基-地"分布式协同编队特征,提出了一种基于多域无人平台运作规则与层网络间逻辑连接失效关系的空基地集群编队可靠性分析算法.用空中网络、通信网络、地面网络组成的3 层轻量化方格拓扑结构代替现实中的集群,在综合考虑随机攻击、蓄意攻击以及区域失效关系、关联失效关系、级联失效关系等依赖关系的条件下设计算法,以网络中最大连通子图为可靠性测度,进行不同编队状态及编队形式下的网络可靠性分析.最后与标准仿真平台进行对比,试验结果验证了算法的可行性、快速性以及资源占用率小等优势.该研究为提升多域无人平台协同编队时的可靠性及相关的防控策略的研究提供了研究基础.
Abstract
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.
