摘要：Wireless sensor node localization is one of the most crucial techniques on wireless sensor network. For reducing localization cost and improving localization accuracy, we propose an improved wireless sensor network DV-Hop localization algorithm. The mobile beacon node is introduced into DV-Hop and allows a moving beacon node to move on the pre-arranged way, continuously broadcast its position information to form multiple virtual beacons. The simulation experiment result shows our method can reduce the localization cost and the complexity of network while improving the node localization accuracy and efficiency
