| 摘 要： | 针对DV Hop算法在估算平均每跳距离时存在较大的误差，提出一种跳距修正的加权定位算法。改进后算法是通过引入平均每跳距离误差修正值，进行加权处理，从而减少了跳距误差，避免了后续计算过程中误差的累积。仿真结果表明，改进的DV Hop算法在不增加硬件开销的基础上，能有效提高定位精度，降低定位误差，具有较好的稳定性，是一种实用的无线传感器网络(WSN)节点定位方案。

| Abstract: | A hop distance correction weighted localization algorithm is proposed aiming at the error of the DV Hop algorithm in estimating average hop distance. The improved algorithm introduces average hop distance error correction and performs the weight processing to reduce the hop distance error, which helps to avoid error accumulation in the process of calculation. The simulation results indicate that the improved DV Hop algorithm reduces localization error effectively and has good stability without additional devices; therefore, it is a practical localization solution for WSN. |
