A reverse power control algorithm based on SNR between nodes' acoustic communication for underwater networks was studied and analysed.Simulations for no power control ,traditional DM control and PCM control show that, communications with power control is better in energy saving and reliability of communication than without power control and at the same time, simulation also show the the PCM have a better control effect than the DM.%研究了海洋水下空间中,水下自组织网节点之间的基于信噪比SNR的反向通信功率控制方法.分别对无功率控制通信和传统的DM(Delta Modulation)和PCM(Pulse Code Modulation)方法功率控制通信进行了仿真.得出功率控制通信比无功率控制通信有更好的节能性及通信的可靠性.同时通过仿真比较得出PCM方法对于实际的海洋环境优于DM方法,有更好的控制效果.
