带时延的WSNs时钟同步算法实验比较

Experimental Comparison of Time Synchronization Algorithms in WSNs with Millisecond Delay

基于时钟同步问题的重要性和难度,学者们研究众多无线传感网络的时钟同步算法。列举了最新的基于一致性的分布式时钟同步协议ATS、WMTS、LSTS算法,它们在有界通信时延情况下都可以实现不同程度的时钟同步。实验结果表明,在毫秒级通信时延下,LSTS算法具有更好的同步效果和稳定性。

Time synchronization in wireless sensor networks has been studied extensively and kinds of time synchroniza- tion algorithms have been proposed due to its importance and difficulty.This paper considers three distributed time synchro- nization algorithms based on consensus which could achieve time synchronization accuracy in different level with bounded random communication delay.
