An improved DV-Hop algorithm based on average hop distance and estimated coordinates

There is a big error in the classic DV-Hop localization algorithm in average hop distance and unknown point coordinates. We propose an improved DV-Hop location algorithm, by improving the average hop distance and introducing a checkout algorithm in the second and third stages of the classic DV-Hop localization algorithm, to improve the position accuracy. The MATLAB simulation shows that in the same test situation, without significantly increasing calculating complexity and requiring additional hardware, the performance of the improved DV-Hop algorithm in wireless sensor network is better compared with the classic algorithm.
