低空无人机群自组织网络弹性综述

Review of Self-organizing UAV Swarm Network Resilience in Low Altitude Airspace

传统无人机(unmanned aerial vehicles,UAV)群评价指标缺少对系统遭受扰动后性能变化的全过程描述,弹性作为能够凸显系统动态变化的特有属性可以集中反映无人机群运行态势,围绕无人机群弹性概念、弹性评估方法、提升系统弹性措施3个方面进行全面综述。从自组织网络弹性概念展开,通过复杂网络对无人机群建模并进行弹性度量,分析了目前主要的弹性评估方法,同时从吸收能力和恢复能力两方面归纳网络弹性的提升措施。最后,综合无人机群弹性研究中亟待解决的关键问题,展望了未来研究方向,为无人机群安全高效运行提供科学指引。

The traditional unmanned aerial vehicles(UAV)swarm evaluation index lacks a description of the whole process of performance change after the system is disturbed.As a unique attribute that can highlight the dynamic change of the system,the resilience can focus on reflecting the UAV swarm operation situation,and a comprehensive review was conducted in three aspects:UAV swarm resilience concept,resilience assessment methods,and measures to improve system resilience.The concept of self-organized network resilience was developed,the complex network was used to model and measure the resilience of the UAV swarm,the main resilience assessment methods were analyzed,and the measures to improve the resilience of the network were summarized in terms of absorption capacity and recovery capacity.Finally,the key problems that need to be solved in the research of UAV swarm resilience were synthesized,and future research directions were foreseen to provide scientific guidelines for safe and efficient UAV swarm operation.
