Complex Networks Under Dynamic Repair Model

Di: Ava

In reality, most of the topological structures of complex networks are not ideal. Considering the restrictions from all aspects, we cannot timely adjust and improve network Complex networks, which exhibit high connectivity, self-organization, small-world properties, and heterogeneity, are susceptible to the rapid spread of local failures, often

This article presents an overview on the state-of-the-art development in complex network controllability and its robustness against malicious attacks and random failures. A network state observer is then constructed using a unique diagonal matrix, which underpins the driver and response-layer networks. By integrating control theory and stability

Therefore, it is necessary to integrate the network’s structure and function in order to develop a comprehensive performance index that can reflect the variation in road network Especially, proactive defense and dynamic repair are flexible and effective methods to ensure network security. Most studies on the cascade of complex networks are based on the

Focusing on complex systems whose dynamics are described with a system of first-order differential equations coupled through a graph, we study generalization of neural The controllability of complex temporal networks is one of the most important challenges of the last decade in this type of network. The main goal of controllability methods is

Complex Network Modeling: Theory and Applications Print Special Issue Flyer Special Issue Editors Special Issue Information Keywords Benefits of Publishing in a Special Temporal complex networks have always been under vari-ous attacks, especially DoS attacks. Attacks cause the network to lose its full controllability. In this paper, the destructive efects of This study introduces a novel dynamic event-triggered control (ETC) strategy to address the fixed-time synchronization (FXTS) challenge in multilayer complex networks facing

We fill this gap by studying a nonlinear weighted model of cascade failure with overloaded edges over synthetic and real weighted networks. This article focuses on the cascading failure problem and node importance evaluation method in complex networks. To address the issue of identifying important nodes in

It then uses the cascading failure model to simulate the dynamic response process of the ecological network under different attack strategies, and uses this to evaluate the

Robustness of complex networks has attracted much attention in diverse disciplines. Most of previous studies did not consider the attack cost. In this paper, the network Two computational methods based on the Ising model were implemented for studying temporal dynamic in co-authorship networks: an interpretative for real networks and Estimation of network resilience, the ability to maintain functionality when failures occur, usually requires prior knowledge of network topology and dynamics. The authors

This section is divided into three subsections: the game process on complex networks, the update rules for the evolution of node game strategies in networks, the broken Reconstructing complex networks from measurable data is a fundamental problem for understanding and controlling collective dynamics of complex networked systems.

Controlling the behavior of a complex network usually requires a knowledge of the network dynamics. Baggio et al. propose a data-driven framework to control a complex

This paper investigates the possibility of saving a network that is predicted to have a cascading failure that will eventually lead to a total collapse. We model cascading failures Reconstructing complex networks and predicting the dynamics are particularly challenging in real-world applications because the available information and data are

The proposed multi-dimensional model evaluates the network resilience from three aspects: absorption ability, resistance ability and recovery ability. In order to enhance the power supply reliability of distribution network under wind disasters and provide assistance for distribution network operators to formulate post disaster Hence, we adopted a new and more universal cascading failure propagation model based on discrete dynamic system.
