Abstract: Nodes in probably most real-world networks have an autonomous
ability (agency) to control their interaction with other nodes. Taking
inspiration from the development of (real) neuronal networks, we
developed a framework to study networks of agents that migrate and grow
to adjust their reciprocal interaction with the embedding network.
Homeostatic regulation of migration and interaction range creates
continuously dynamic networks with a range of properties and structures
observed in real-world networks. These hierarchical networks show
pronounced clustering, defining a hierarchical mesoscale structure. This
structure is subject to external influences (top-down) acting on
node-level properties and allows us to study how extrinsic factors can
modulate the self-organization of networks in a homeostatic process. Our
results suggest a new perspective on the development of spatial
structure, connectivity and the impact of external influences in many
natural systems.
