| 摘 要： | 提出了改进DV—Hop算法，通过限制跳数实现局部范围内的定位信息提取，同时调整平均每跳距离并对其进行加权实现校正，以此提高定位精度。理论分析及仿真结果表明，该算法能够减少节点间通信量，降低通信成本，提高定位精度。

| Abstract: | A modified DV-Hop algorithm is proposed for node localization. The localization information extraction within local network is achieved by limiting hops. The average hop size is adjusted and weighted for distance correction to improve the localization accuracy. Both the theoretical analysis and simulation experiments demonstrate that the algorithm can decrease the communication data, lower the cost. And improve the localization accuracy. |
