针对传统的DV-Hop算法在定位过程中出现的容易引起误差的问题，提出了一种综合考虑所有信标节点的平均跳距并引入权值修正，将信标节点当作未知节点计算误差进而优化精度的距离估计算法，使网络平均跳距和节点位置估计值更加准确。通过相关仿真实验表明：改进算法优化了原算法的定位精度和定位稳定性，达到了预期目标。

Aiming at the traditional DV-Hop algorithm easily caused error,the current thesis proposes a comprehen-sive consideration of all beacon nodes average one-hop distance and introducing weights corrected results. At the same time use beacon nodes as unknown nodes calculating error and use the error optimizing accuracy. Finally makes the average one-hop distance and node position estimates more accurate. Theoretical analysis and simulation results show that the proposed algorithm has better locating performance in locating precision and precision stability, achieve the expected goal.
