Abstract: Cascading failures in coupled map lattices with Harmonious Unification Hybrid Preferential Model (HUHPM) were investigated through simulation analysis methods in this paper. Two attack strategies: deliberate attack and random attack were adopted in this fixed node number network. According to simulation result, the HUHPM network has better robustness in random attack than in deliberate attack. In addition, the hybrid ration has an important effect on cascading failures of the HUHPM network. In the deliberate attack case, the network became more robust to deliberate attack with the increasing of the random preferential attachment. But in the random attack case, the network became more robust to random attack with the increasing of the deterministic preferential attachment. Therefore, in practical applications, the robustness of HUHPM network can be enhanced by tuning the hybrid ration.

Key words: Harmonious Unification Hybrid Preferential Model (HUHPM), couple map lattice, cascading failure, hybrid ration, robustness

摘要: 将耦合映像格子的相继故障模型作用于和谐统一的混合择优网络模型(HUHPM),通过仿真分析的方法研究了和谐统一混合择优网络的相继故障行为。仿真中采用了蓄意攻击和随机攻击两种策略。仿真结果表明,同规模的和谐统一混合择优网络抵抗随机攻击的能力比蓄意攻击要强;另外,网络的总混合比对这类网络相继故障行为的扩散有很强的影响,在蓄意攻击下,随着随机性连接的逐渐增加,网络的抵抗蓄意攻击的能力逐渐增强,而在随机攻击下则正好相反,即随着确定性连接的增加,网络抵抗随机攻击的能力越来越强。因此,在实际应用中可以通过调节混合比来增强这类网络的鲁棒性。
