Abstract
To solve the inaccurate node localization in WSN, this paper first analyzes the problems in current DV-HOP algorithm, takes the received signal RSS as a reference standard through the weighted centroid algorithm, effectively reduces the localization errors, and adopts the improved two-dimensional hyperbola algorithm in the distance estimation to make the estimated distance more accurate. The simulation results show that the presented algorithm has been significantly improved compared to the algorithms in literature, and enhanced the localization accuracy to a certain extent.
