- W2389001650 abstract "As to the problem of traditional DV-Hop algorithm's low locating accuracy, weighted DV-Hop algorithm optimizes average one-hop distance of unknown nodes. Based on weighted DV_Hop algorithm, a novel algorithm under the circumstance of existing GPS localization error is proposed to optimize the whole network's average one-hop distance of beacon nodes by using least squares, and choose hyperbolic algorithm rather than trilateration to estimate the coordinates.Average localization error of a single random simulation can be reduced 13.01% than traditional DV-Hop algorithm's,8.94% than weighted DV-Hop algorithm's, and results of the repeated simulations demonstrate that the improved algorithm has significantly better locating performance in locating accuracy and accuracy stability similarly." @default.
