跳数和跳距修正的距离向量跳段定位改进算法
Improved DV-Hop localization algorithm based on hop count and hop distance modification
摘要
Abstract
The positioning error of the DV-Hop localization algorithm is big due to the sensing node's random distribution existing in the wireless sensor network. Therefore the hop count and hop distance modification method is used to improve the DV-Hop localization algorithm. The node communication distance is introduced in the process of calculating the hop count of the bea-con node and unknown node to make the actual hop count between the nodes more accurate. The linear search algorithm is used to obtain the average hop distance of the optimal beacon node to make the average hop distance of the beacon node more accu-rate. The comparative simulation results show that the algorithm has improved the positional accuracy greatly,and its accuracy is increased by 15%.关键词
