Abstract :
The traditional DV-HOP algorithm for three-dimensional localization precision is not good enough to use. Its positioning deviation is too large to find out the unknown nodes, and the scope of coverage is too small to find out all the nodes. Because of these shortcomings, a novel three-dimensional localization DV-Hop algorithm (NTLDV-HOP) is proposed. The proposed algorithm revises per jump distance to enhance the accuracy of distance calculation between unknown nodes and anchor nodes, and uses the Total Least Squares (TLS) method to modify the positioning deviation of the anchor node itself. Simulation shows that the NTLDV-HOP improves the location accuracy.
