摘要
为了量化、客观地评估网络在复杂环境下的抗毁性能评估,提出了一种多目标网络抗毁性评估方法。该方法引入结合粒子群算法的环境参数集概念,用于表示各项指标在不同环境下的重要程度,以体现不同环境对网络抗毁性能指标的不同要求;并从节点角度考虑将网络的鲁棒性、可用性、适应性与成本等目标综合起来,给出一种量化反映网络在不同环境下综合抗毁性能的算法,以弥补现有方法主观、非量化及无法适应复杂环境等缺陷。通过仿真实验验证了该方法的有效性。
In order to evaluate the network survivability quantificationally and objectively in complex environment,a muti-objects network survivability evaluation method was proposed.The concept of environment parameter set based on PSO was introduced,which was used to show the indexes’weight and the different requirements for network survivability index in different environments.And from the view of node,considering the itegration of the network robust,availability,adaptation and cost,an algorithm which can reflecte the general network survivability performance in different environment was proposed.The problems of the existing methods such as subjective,non-quantification,poor adaptation,were solved.The method was verified through simulation.
