Abstract
The node localization is an important problem in wireless sensor network (WSN). An improved algorithm is proposed by analyzing the deficiencies of random distribution in DV-Hop. Different from the previous results, minimum mean-squared error (MSE) and inverse distance weighting method are adopted to deal with the average one-hop distance in improved algorithm. Improved algorithm and DV-Hop are simulated by MATLAB R2015b, and the results of these two algorithms are analyzed and compared. The results show that the positioning accuracy is improved on the condition of no increasing complexity and cost.
