L Zhen, LI Ya-jie, SUN Yan-fei, et al. An improved and modified localization algorithm based on DV-Hop[J]. 2010, 29(8): 31-33. DOI: 10.13873/j.1000-97872010.08.021.
Self-positioning technology is a supportive technology in wireless sensor networks.The shortcomings of DV-Hop algorithm is analyzed and amending the anchor node’s calculation of the average distance of each hop.More anchor node is allowed to participate in the final position calculation and the weighted centroid algorithm is adopted.The result of the simulation by Matlab shows that the modified algorithm is better than the original one in precision.The suitable application scene of the modified algorithm is derived.
