An Asymmetric Coupling Wireless Sensor Network Synchronization Control Model

The WSN(Wireless Sensor Network) is a certain kind of complex networks which characters large scale and time varying topology. To make good use of the large-scale character to realize MIMO cooperation signal transmission and chaotic secure communications, it is of great importance to solve the synchronization problem in WSNs. Most of works so far on the network synchronization focused on the regular networks. However, due to the time varying of wireless channel and the failure of nodes, which make the topology of WSNs vary with time, it is difficult to model and then analyze the WSN synchronization problem. Inspired by the work of Belkh, this paper presents an asymmetric coupling wireless sensor network synchronization control model. By the theory analysis and the example illustrated in the paper, it shows that this model can significantly improve the synchronization performance of networks.
