摘要

时间同步是传感器网络中各种应用必不可少的基础设施。本文介绍了一种基于现场可编程门阵列(FPGA)的时间戳方法，并将其应用于参考广播同步(RBS)中。然后，提出了动态调整时间同步(DATS)协议，通过动态调整使时钟补偿连续逼近最优补偿，使节点能够快速响应外部环境的变化。实验结果表明，DATS的同步精度达到0.9655±0.9810µs。

Dynamic Adjusting Time Synchronization for sensor networks

Time synchronization is an essential infrastructure of various applications in sensor networks. In this paper, a time-stamping approach using field-programmable gate array (FPGA) is introduced which is applied to Reference broadcast synchronization (RBS). Then, Dynamic Adjusting Time Synchronization (DATS) protocol is proposed which enables the clock compensation to approach the optimal compensation continuously through dynamic adjustment and enables the node to make quick response to external environmental changes. The experimental results show that the synchronization accuracy of DATS achieves 0.9655 ± 0.9810 µs.
