Time synchronicity works as a popular requirement in wireless sensor networks. Pulse-coupled oscillators similar to firefly flashing and synchronization via discrete pulse coupling are widely used in wireless sensor networks. In this article, we have studied the time synchronization with communication delay in the nearest neighbor network of distributed sensors, based on the pulse-coupled oscillators model of synchronicity achieved by biological systems. First, we present a linear pulse-coupled oscillators model with coupling delay and the model is used to analyze the wireless sensor networks synchronization with communication delay. Second, we mathematically analyze the firing behaviors in the linear pulse-coupled oscillators network using the delayed excitatory coupling and track the synchronization process of the two and multi-oscillators and obtain the synchronization conditions from the regression mapping. Finally, through the proposed model implementation in the wireless sensor networks simulation framework, we demonstrate that the multi-oscillators system can be synchronized from a random starting stage distribution under linear phase responding functions and the nearest neighbor communication. The results show that our approach can achieve clock synchronization in wireless sensor networks with delayed nearest neighbor communication.

最近邻无线多跳网络中带延迟的线性脉冲耦合振荡器模型时间同步研究

时间同步是无线传感器网络中的普遍要求。类似于萤火虫闪烁和通过离散脉冲耦合同步的脉冲耦合振荡器广泛用于无线传感器网络。在本文中,我们基于生物系统实现的同步性脉冲耦合振荡器模型,研究了分布式传感器最近邻网络中具有通信延迟的时间同步。首先,我们提出了一个具有耦合延迟的线性脉冲耦合振荡器模型,该模型用于分析具有通信延迟的无线传感器网络同步。第二,我们使用延迟激发耦合对线性脉冲耦合振荡器网络中的激发行为进行数学分析,并跟踪两个和多个振荡器的同步过程,并从回归映射中获得同步条件。最后,通过在无线传感器网络仿真框架中提出的模型实现,我们证明了多振荡器系统可以在线性相位响应函数和最近邻通信下从随机起始阶段分布同步。结果表明,我们的方法可以在具有延迟最近邻通信的无线传感器网络中实现时钟同步。通过在无线传感器网络仿真框架中提出的模型实现,我们证明了多振荡器系统可以在线性相位响应函数和最近邻通信下从随机起始阶段分布同步。结果表明,我们的方法可以在具有延迟最近邻通信的无线传感器网络中实现时钟同步。通过在无线传感器网络仿真框架中提出的模型实现,我们证明了多振荡器系统可以在线性相位响应函数和最近邻通信下从随机起始阶段分布同步。结果表明,我们的方法可以在具有延迟最近邻通信的无线传感器网络中实现时钟同步。
