This paper presents a kind of DV-Hop localization algorithm based on distance correction of nodes. This algorithm introduces the concept of distance correction factor and combines with the node communication radius to correct the average distance of each hop between unknown node and anchor nodeand makes it be closer to the real value. The simulation results show that the proposed algorithm can reduce the average localization error of node, and when the value of distance correction factor is 0.8the average localization error of node under DA-DV-Hop localization algorithm is reduced 15.53% than the traditional DV-Hop localization algorithm.
