摘要

提出了一种多跳时间同步的自动水下航行器(auv)执行割草机轨迹的用例。这项工作展示了一种时间同步协议，可以解决水下多跳场景下的移动性问题。选择现有的多普勒增强时间同步(DE-sync)协议，并将其扩展到特定于应用程序的多跳场景。它进一步考虑在每一跳的消息交换后经过的时间持续时间内的错误分析。利用MATLAB进行了仿真。我们观察到DE-sync在同步错误方面表现出比其他类似协议更好的性能。误差随跳数的增加而增加，但有限制。

Application of Multi-hop Time synchronization on a Network of AUVs Performing Lawn Mower Trajectory

This paper presents a use case of multi-hop time synchronization for autonomous underwater vehicles (AUVs) performing lawn mower trajectory. The work showcases a time synchronization protocol that could address mobility in multi-hop underwater scenarios. An existing time synchronization protocol named Doppler-Enhanced time synchronization (DE-sync) protocol is chosen and extended to an application-specific multi-hop scenario. It further considers the error analysis in the elapsed time duration after message exchanges in each hop. Simulations have been performed using MATLAB. It is observed that DE-sync shows better performance in terms of synchronization error than the other similar protocols. It is also found that error increases with the number of hops but with limited bounds.
