|
摘要
针对库区复杂的环境监测进行研究。在构建适用于库区特定环境的无线传感器网络监控系统下,针对节点定位精度和使用寿命的要求,采用改进后的最小二乘法对节点坐标进行求精,在保证定位精度的同时降低节点能耗。仿真结果表明,本算法能够有效的保证定位精度,实现预警位置的精确定位。
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.
