This paper studies the node localization algorithm of the wireless sensor network. This localization algorithm can efficiently position a node. The improved algorithm introduces the mobile signal node into DV-Hop localization algorithm. This mobile signal node moves in the defined network path and continuously broadcasts information on self nodes to form multiple virtual beacons. This paper studies the weighted algorithm of the average hop distance and dynamic selection algorithm of beacon node to reduce localization cost and network deployment complexity and improve localization precision and efficiency of a node. The test results indicate that the improved localization algorithm improves localization precision, reduces communication consumption of the localization algorithm and improves the localization efficiency of the nodes in the wireless sensor network.
