The paper aims to present a new scheme of synchronization-based topology identification for a class of weighted general complex dynamical networks with time-varying coupling delays. By combining the adaptive control method and the Razumikhin-type theorem, a new feedback technique to identify the exact topology of the dynamical networks with time-varying coupling delay has been proposed. In comparison...
This paper formulates a new model of complex spatio-temporal switching network with coupling delays. Not only the dynamics of each node and the topology of the network is switched between different mode at different time intervals. A set of sufficient conditions for synchronization of the spatiotemporal switching network with coupling delays are presented in the state to be passive. Finally, an illustrative...
This paper discusses the robustness properties of a novel decentralized strategy for synchronization of complex networks based on adaptive local gains. Namely, the strategy assumes that each vertex adaptively selects the coupling strength with all of its local neighbours. The strategy was proved to guarantee synchronization and it is shown here to be surprisingly robust to topological variations of...
We consider the synchronization problem of an arbitrary number of coupled nonlinear oscillators with delays in the interconnections. The emphasis is on coupled Lorenz systems. The network topology is described by a directed graph. Unlike the conventional approach of deriving directly sufficient synchronization conditions, our approach starts from a linearized stability analysis in a (gain, delay)...
In South-East Asia, huge swarms of fireflies synchronously emit light flashes to attract mating partners. The underlying principle can be used to implement a robust and scalable distributed synchronization approach in wireless sensor networks. This paper describes the adaption of this principle for wireless sensor networks using battery-powered low-cost nodes based on an off the shelf IEEE 802.15...
