Abstract
In this paper,four improved DV-Hop localization algorithms are proposed for improving the shortcomings of DV-Hop localization algorithm with low accuracy,and simulation tests and performance analysis are carried out.The node localization accuracies of the four improved DV-Hop localization algorithms are significantly higher than that of the classical DV-Hop localization algorithm.The positioning accuracy of the four improved DV-Hop localization algorithms are,in descending order,improved DV-Hop localization algorithm 4,improved DV-Hop localization algorithm 1,improved DV-Hop localization algorithm 2,and improved DV-Hop localization algorithm 3.Among them,the improved DV-Hop localization algorithm 4,which corrects the average distance per hop,has the highest localization accuracy,and it can fully satisfy the requirements of practical applications.关键词
