In order to hold the hardware cost is not the premise of improving the positioning accuracy of sensor nodes, the paper proposed the node localization research of the underground wireless sensor networks based on DV-Hop and Ant Colony Optimization, this method of non-ranging DV-Hop algorithm calculate the distance between unknown nodes and beacon nodes, with the method of triangular positioning algorithm to determine the location of unknown nodes, and through the ant colony optimization to improve accuracy of the unknown node location. To verify the feasibility of the method, with the comparison of the traditional orientation algorithms and the improved algorithm by MATLAB simulation, experimental results show that the improved algorithm has higher accuracy.
