| 摘 要： | 无线传感器网络的时间同步是无线传感器网络的一个重要的研究方向.本文利用时钟偏移量误差的规律性,提出基于指数时延的无线传感器网络时钟同步估计算法.本算法是一种基于发送者同步模型,在DMTS算法的基础上引入指数时延得到的.理论与仿真实验都证明本算法对时钟偏移量的估计是相合的,同时实验还证明本算法比DMTS算法具有更高的精度和稳定性.

| Abstract: | Time synchronization is an important research orientation of Wireless Sensor Networks. According to the law of clock offset errors,this paper presents a clock synchronization estimation algorithm of Wireless Sensor Networks with exponential delay. The algorithm is based on sender synchronization model,and gotten from DMTS algorithm imported exponential delay. It is proved in theory and by emulation experiment that the estimation of clock offset in this algorithm is synodical. It is shown in emulation experiment that this algorithm have higher precision and stability than DMTS algorithm. |
