Partial synchronization and controllability of asymmetric coupling wireless sensor networks

Abstract

For a uniform complex dynamics networks, a synchronization criterion of this model is given by constructing a Lyapunov function. In this paper, we present a new asymmetric coupling wireless sensor networks (WSNs) synchronization control algorithm combining with clusters, it aimed at the application of a large scale, high-density WSNs. It is proved that this network can achieve synchronization dynamically under the control scheme. This model avoids the research under the specific network topology of network synchronization problems, instead of researching how to improve the synchronization performance of the network from the perspective of cybernetics. Particularly, this controller has strong robustness against the coupling strength and topological structure of the network. Numerical simulations show this model can significantly improve the performance of synchronization for WSNs. Our results offer important references on the performance issues depending on specific application scenarios of WSNs.
