基于耦合振荡器模型的WSN时间同步算法--以ZigBee网络为例
Wireless sensor networks time synchronization algorithm based on coupled oscillators model-exemplified by ZigBee networks
摘要
Abstract
The paper proposes the ZigBee network time synchronization algorithm based on oscillator model. The algo-rithm solves the delay in the process of ZigBee network data acquisition, making the entire ZigBee network trend to be synchro-nized and improving the system’s accuracy. The paper introduces the refractory period method to solve the repeated excited problem caused by delay between the nodes and discusses the impact of various parameters of this model on synchronization. The model uses a dynamic function to describe states of different moment of the oscillator, solves the problem of excessive cal-culation in classic pulse-coupled oscillator model, and passes the test experiments to verify the feasibility of the algorithm.关键词
