| 摘 要： | 提出了基于跳距的加权质心定位算法，用信标节点和未知节点之间的跳距来确定质心算法中各信标节点的加权因子，以提高质心算法的定位精度。对普通质心算法和改进后的质心算法进行了模拟仿真，结果表明所提出的算法从总体上看具有较好的定位效果。

| Abstract: | A weighted centroid localization algorithm based on communication hops for wireless sensor network is presented,the hops between the beacon nodes and an unknown node are employed to be the weighted factors of the beacon nodes for improving the localization accuracy.Simulations on the common centroid algorithm and the improved centroid algorithm have also been performed,results demonstrate the later has the better localization effects in general. |

| Keywords: | wireless sensor networks node self-localization centroid algorithm simulation |
