At present, the optimization method has the poor energy saving effect and the large impact on the actual measured rate and success ratio of data in single - hop network. Therefore, a method to optimize energy consumption of actual measured data in low - power single - hop network based on optimal stopping rule was proposed. Based on the single - hop network structure, we determined the attenuation coefficient of single - hop network signal during measured data. Through the research on main part of measured data in single - hop network, we optimized the energy consumption model of actual measured data and determined the energy consumption of node communication unit. Meanwhile, we introduced signal attenuation coefficient to determine the total energy consumption of actual measured data in single - hop network. Based on the optimal stopping rule, we deduced the optimal stopping rule and the optimal energy consumption efficiency of sending terminal in single - hop network. Finally, we built the model of the minimum energy consumption of actual measured data in single - hop network and introduced the total energy con- sumption of actual measured data into the model. Thus, we achieved the energy consumption optimization of actual measured data in low power consumption single - hop network. Simulation results show that the proposed method reduces the energy consumption of actual measured data. Meanwhile, it has less effect on the actual measured speed and transfer success rate of data.
