Abstract

Natural phenomena such as the synchronization of fre ies, interactions between neurons, and the formation of earth- quakes are commonly described by the mathematical model of pulse-coupled oscillators. This article investigates the be- havior of this model when oscillators form a meshed network, i.e. nodes are not directly coupled to all others. In order to characterize the synchronization process of populations of coupled oscillators we propose a metric that allows to char- acterize the level of local synchronization. We demonstrate the merits of the proposed local metric by means of two case studies that examine the effect of imperfections on the synchronization process, namely the presence of frequency drifts and propagation delay
