Shaojun Yu, Yujian Wang, Kaiguo Qian · 2021
The adaptive time synchronization method of low energy consumption and low duty cycle wireless sensor networks is studied. The adaptive controller and parameter adaptive law of the corresponding wireless sensor networks are calculated respectively in the case of known coupling weight and unknown coupling weight. In order to meet the requirement of low duty cycle with low energy consumption, the finite time stability theorem and Lyapunov stability theory are used In this paper, the error dynamic of complex dynamic network is modified, and the upper bound of synchronization transition time is estimated. Finally, a numerical example is used to verify the effectiveness of adaptive time synchronization in wireless sensor networks. The experimental results show that the adaptive time synchronization method considering low energy consumption and low duty cycle has better performance and higher practicability in practical application.
