In the TPLSOA , a three-point estimation node coordinate model is designed. The model is used to calculate the estimated coordinates of unknown nodes, and the calculated node position is taken as the initial position of the seeker optimization algorithm(SOA). The improved SOA is employed to optimize the position of unknown nodes. The simulation results show that the proposed algorithm has higher localization accuracy in comparison with other localization algorit
