Abstract—Localization in Mobile Wireless Sensor Networks(MWSNs) has become a focus research in recent years, path planning algorithm makes great influence on localization performances. There are abundant existing path planning methods, but few of them can be applied in MWSNs. In order to avoid energy and resource waste caused by anchors traversing sparse area randomly, we first realized anchors move adaptively in MWSNs. Then, aim at the deficiency of high anchor density, we proposed a scheme to make anchors move in pairs by cooperation, ensuring that there will be at least two one-hop or two-hop anchors around sensor nodes. Thus on the premise of high positioning accuracy low energy consumption, we efficiently reduce the number of anchors and increase the utilization rate. The simulation results verify the algorithm performance
