The node localization algorithm of Wireless Sensor Network(WSN) in three-dimensional space is one of the hot research topics currently.A three-dimensional DV-Hop localization algorithm based on mobile Agent was proposed by analyzing the lack of the existing three-dimensional localization algorithms,extending the rang-free algorithm of DV-Hop to three-dimensional space,and improving the performance in traffic and positioning accuracy.The simulation results show that the proposed algorithm can position the sensor nodes in the three-dimensional environment effectively,the beacon nodes' density and communication radius have little effect on the positioning error and the coverage,and the positioning accuracy and coverage relative to other algorithms have improved significantly.
