摘要：In order to reduce localization error of the sensor node, a novel node localization algorithm (DVHop-Steff) is proposed in this paper based on DV-Hop algorithm and Steffensen iterative method. Firstly, DV-Hop algorithm is used to obtain location position of wireless sensor nodes; and then Steffensen iterative method is used to correct the locate results of DV-Hop algorithm and achieve higher localization precision, finally, the performance of the proposed algorithm is tested by simulation analysis. The results show that the localization precision of the proposed algorithm has been improved significantly and has more wide application scope.
