Perturbation Centrality


Definition

Perturbation centrality is a measure of dynamic network centrality.
Perturbation centrality of node i was defined as the reciprocal of silencing time retrieved by using a Dirac delta type starting perturbation of 10*n units, where n is the number of nodes in the network, using a dissipation value of 1.
Silencing time of node i was the first time when all of the nodes had an energy value less than a pre-set minimal threshold after an initial perturbation started from node i.
