A New FADV- Hop Location Algorithm Based on Firefly Algorithm

针对无线传感器网络中距离向量-跳距(Distance Vector-Hop,DV-Hop)定位算法中定位误差积累、定位精度不高的缺陷,本文采用萤火虫算法(Firefly Algorithm)的策略,提出一种FADV-Hop定位算法,将DV-Hop定位算法中定位精度不足的问题进行多维优化。通过理论推理仿真,实验结果表明,FADV-Hop定位算法降低了定位误差,提高了定位精度。

In Wireless Sensor Network Distance Vector- Hop localization algorithm in positioning error accumulation,defects of the positioning accuracy is not high,the Firefly algorithm strategy,a FADV- Hop location algorithm is proposed,into the problem of DV-Hop localization algorithm in positioning accuracy is insufficient for multidimensional optimization problem. By theoretical and simulation results,the experimental results show that the FADV- Hop positioning algorithm reduces the positioning error and improves the positioning accuracy.
