By constructing the piecewise linear function from samples, it is able to approximate the measured metric more precisely. Compared with current popular sampling algorithms, FASM algorithm can provide more precise estimation of metric under the same samples. In the condition of retaining the same approximation errors, our adaptive sampling methodology only requires fewer samples, which will save sampling costs considerably during sampling process.

与当前常用的抽样算法相比，在采集相同的样本数量情况下，本文的拟合模型对指标进行的估计更准确、稳定；而在保持相同的拟合误差时，自适应抽样算法则可显著减少所需采集的样本数量，节约数据采集过程的代价。

The distance between the reactive sensor node and the target node is estimated by using the value of RSSI, since the strength of radiation signal and the square of distance is inversely proportional. We proposed a method to derive the position of the target node based on the theory of radical center. With data from three reactive nodes, the position of target node can be analytically estimated.
