时间序列关键点表示算法及应用

Key point representation algorithm of time series and its application

提出了一种时间序列关键点表示算法,在无线传感器节点处,利用该算法找到关键点并进行数据传输。通过实验验证,该算法较好地拟合了原始数据,计算量少,传输数据量少,有利于降低农业物联网无线传感器中的功耗。

In order to reduce the power consumption of wireless sensor in Agricultural Internet of Things,this paper proposes to use the proposed algorithm to find the key points and carry out data transmission at the wireless sensor node,which greatly reduces the amount of data transmitted,thus reducing the power consumption.It is proved by experience that this algorithm fits the original data well with less calculation and less data transmission,which is helpful to reduce the power consumption of wireless sensors in the Agricultural Internet of things.
