To address the low accuracy and poor stability of the traditional DV-Hop algorithm, this paper proposes an improved DV-Hop algorithm based on a multi-population genetic algorithm (MPGA). Based on the minimum mean square error criterion, the algorithm introduces a weighting factor to correct the average hop distance of anchor nodes. By incorporating a weighting matrix, the least squares method is modified to estimate the coordinates of unknown nodes. To further optimize the coordinates of unknown nodes while reducing the number of iterations, a multi-population genetic algorithm is employed. To evaluate the localization accuracy of the algorithm in anisotropic networks, a radio irregularity model is also considered. The simulation results show that compared with traditional DV-Hop algorithms and common heuristic optimization DV-Hop algorithms, this algorithm significantly reduces positioning errors and improves positioning stability. It can provide algorithmic foundation for subsequent implementation on parallel or distributed computing platforms.
