Research on an Improved Particle Swarm Algorithm in DV-HOP Algorithm

The node positioning error in wireless sensor has always been the focus of research. A way of an improved particle swarm optimization algorithm being proposed to correct the DV-Hop error positioning method, which can reduce the estimate error for the distance between unknown nodes and anchor nodes. The matlab simulation results show that the improved algorithm can effectively improve the positioning accuracy of the sensor nodes than the traditional algorithm. The simulation results have verified the effectiveness of the improved algorithm.
