基于信号幅度衰减测距的水下定位方法
Underwater location method based on signal amplitude attenuation
摘要
Abstract
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.关键词
