Abstract:Aiming at the problem of low location accuracy of3D underwater acoustic wireless sensor network nodes caused by various interference sources in underwater environment， an improved 3 D underwater acoustic wireless sensor network node location method based on Gaussian filter and quasi Newton method was proposed. Firstly， based on the transmission loss model of underwater acoustic signal， the transmission loss was sampled. Secondly， the Gauss filter was used to process the data， and the processed data were substituted into the improved ranging model for distance estimation. Finally， combined with the multilateral location method， the least square solution of the estimated coordinates of the unknown nodes was obtained. The solution results of the position equations were substituted into the quasi Newton algorithm， and the solution close to the actual value was obtained. The simulation results showed that the proposed method reduced the error of node ranging， and the ranging results were better than the traditional ranging methods and the ranging methods based on PF， RF and KF. Compared with ASTL-GWO， ASTL-ASPSO and ASTL-RQ-PSO， the location accuracy was improved by 49% ，31% and 9% respectively.
