Synchronization is referred to the adjustment of the rhythmicity between two or more interacting oscillatory systems whereas chimera states is a symmetry-breaking state and defined as a coexistence of incoherent and coherent populations in a network of identically coupled oscillators. The effect of the interaction function and the underlying interacting coupling topology on the emergence of synchrony and chimera states will be discussed. By considering the various types of network topologies, the synchronization property will address in the time-varying network. The characterization and robustness of several collective dynamical states are investigated through the different types of measurements.
