摘要
Node localization is the foundation of the wireless sensor networks. The traditional DV-Hop localization algorithm has been studied in this paper. In order to solve the problem of DV-Hop localization algorithm, an improved DV-Hop localization algorithm has been proposed. Which uses correction value reducing the measurement average hop distance error and selecting optimal anchor nodes by APIT algorithm. The simulation results demonstrate that, the improved localization algorithm(DV-SCA) has a better localization accuracy than the original DV-Hop algorithm.
