As the DV-Hop algorithm in wireless sensing does not perform well in terms of accuracy, a DV-Hop sensor node location algorithm based on the Steffensen iteration method is presented in this paper. First, the wireless sensor nodes are located roughly through the DV-Hop algorithm; then, the location result is checked and corrected with the Steffensen iteration method, to realize accurate location. The simulation experiment shows that the node location accuracy is improved significantly by using the algorithm presented in this paper, which is more widely applicable.
