Molavi, A., Hamzehpour, H., & Shaebani, R. (2024). Vulnerability of Transport through Evolving Spatial Networks. arXiv preprint arXiv:2407.17977v3.
This research paper investigates the resilience of evolving spatial networks, specifically porous lattice structures, to targeted attacks on central transport hubs identified using betweenness centrality. The study aims to understand how the hierarchical blockage of these hubs affects the network's connectivity and overall transport efficiency.
The researchers employed a simulation-based approach using a square lattice with randomly occupied sites representing a porous medium. They utilized Dijkstra's shortest-path algorithm to determine optimal paths between all node pairs and calculated the betweenness centrality of each node. The node with the highest centrality was iteratively blocked, simulating a targeted attack, until the network became disconnected. The process was repeated for various network sizes and initial occupation fractions.
Optimizing transport based solely on betweenness centrality can have detrimental effects on the resilience of spatial networks under targeted attacks. The study highlights the importance of considering network structure and potential vulnerabilities when designing resilient transport systems.
This research contributes to the understanding of transport dynamics and resilience in spatial networks, with implications for various fields such as urban planning, infrastructure design, and material science. The findings provide insights into designing robust networks capable of withstanding targeted disruptions.
The study focuses on porous lattice structures with specific boundary conditions. Further research could explore the applicability of the findings to other spatial network topologies and real-world scenarios. Investigating mitigation strategies to enhance network resilience under targeted attacks is another promising avenue for future work.
