The role of degree-weighted couplings in the synchronous onset of Kuramoto oscillator networks

Abstract

This paper investigates the role of asymmetrical degree-dependent weighted couplings in synchronization of a network of Kuramoto oscillators, where the conditions of coupling criticality for the onset of phase synchronization in degree-weighted complex networks are arrived at. The numerical simulations visualize that for networks having power-law or exponential degree distributions, asymmetrical degree-weighted couplings (with increasing weighting exponent β ) increases the critical coupling to achieve the onset of phase synchronization in the networks.
