Meaning – The term hierarchical network, refers to the network in which processing and control functions are performed at several levels by computers especially suited for the functions performed.
Hierarchical network models are defined as iterative algorithms that are used to create networks that are able to recreate the unique properties of the scale-free topology and the high clustering of the nodes at the same time. These characteristics are widely observed in nature, from biology to language to some social networks.
The hierarchical network model is part of the scale-free model family sharing their main property of having proportionally more hubs among the nodes than by random generation.
Example of usage – “In automation, in order to achieve the desired tasks in a timely and organized manner, hierarchical networks are used to accomplish them, using the most suitable computers available for the tasks.”
