针对无线传感器网络（WSNs）定位过程当中传统的DV‐Hop定位算法在计算锚节点与未知节点之间的平均跳距时存在较大误差的问题，论文根据蛙跳算法（S FL A ）计算速度快，全局搜索寻优能力强的优势，结合定位的实际问题，提出了一种改进的蛙跳算法。并将其引入到DV‐Hop的算法设计中，实现节点的定位。

The traditional DV‐Hop localization algorithm has a big error in calculating the average between anchor node and unknown node jump distance during wireless sensor network(WSNs) positioning process .In this paper ,leapfrog algo‐rithm(SFLA) calculates speedly and has strong ability for global search optimization .Combining the actual problems of posi‐tioning ,an improved leapfrog is proposed .Through introducing the DV‐Hop algorithm design ,it completes the positioning of the node .
