Hub-regions
Hub-regions are highly connected areas in complex networks that serve as central points of integration and distribution, playing crucial roles in network resilience and information flow.
Hub-regions
Hub-regions represent critical nodes within complex networks that exhibit exceptionally high connectivity and serve as central points of integration. These regions are characterized by their disproportionate number of connections compared to other nodes in the network, making them essential for efficient information flow and network stability.
Characteristics
Hub-regions typically display several key features:
- High degree centrality
- Strong betweenness centrality
- Efficient information processing
- Vulnerability to targeted attacks
- Resilience-promoting properties
