【Abstract】 Makes the research of the environment monitor in the complex reservoir area.By building a wireless sensor network monitoring system for the specific environment of the reservoir area,the paper mainly studies on the node localization precision and service life,and considering the nodes energy consumption,the paper uses the improved least square algorithm to improve the node localization precision.The simulation in MATLAB proves that the improved simplify LSM can not only improve the localization precision effectively,but also reduce the node energy consumption;the accurate localization of early warning can be effective achieved.更多还原
