Abstract

In order to reduce the hop size error and improve the location accuracy, a three-dimensional DV-hop location algorithm (3D-HCRL) based on hop size correction and region location is proposed in this paper. Firstly, the RSSI signal strength value is used to calculate the distance value, and the similar path search algorithm is used to correct the one-hop count and multi-hop count distance between the anchor node and the unknown node to reduce the hop size error and algorithm overhead. Secondly, region location is used to reduce the cumulative error caused by location, and the range of each location and the selection of anchor nodes are controlled by setting hop count threshold and node reliability. Finally, the minimum maximum method is introduced to calculate the unknown node location after region location. Experimental results show that the location accuracy of the proposed algorithm is better than 3DDV-hop location algorithm, TDGT location algorithm and 3D-WFLS-DVHOP location algorithm, and can effectively solve the location requirements in practical applications.
