摘　　要：无线传感器网络中节点规模大、能量有限、可靠性差、随机部署,无线模块的通信距离有限,虽然运用全球定位系统是个很好的选择,但是其体积大、成本高、能耗多而且需要基础设施,不适用于低成本、自组织的无线传感器网络。通过研究发现,基于信号幅度衰减测距的水下定位方法不仅能够满足无线传感器网络节点定位的要求,而且其成本较低,易理解及操作,精度高。As the network nodes of the wireless sensor have many features,including large scale,limited energy,poor reliability,random deployment,the limited communication of wireless module,so using global positioning system is a good choice,but its large volume,high cost,energy consumption and more needed infrastructure does not apply to low cost and self-organizing wireless sensor networks.By studying,the underwater location method basing on signal amplitude attenuation is very good.It can meet the wireless sensor network node positioning requirements,meanwhile,it has many advantages including low cost,easy understanding and high accuracy.
