As a result of the shortage of the positional accuracy for DV-Hop location algorithm in wireless sensor networks,the article proposes a modified DV-Hop algorithm.The improved algorithm introduce uniform quantization model into the original one to improve the accuracy of every period of jump distance and least square method to solve accumulated error in the location.The simulation results prove that the improved algorithm has prominent improvement in positioning accuracy of unknown nodes.

Key words: wireless sensor network;DV Hop;node location
