%X Node localization in wireless sensor networks(WSN)is treated as a functional dual of target tracking from a novel perspective in the paper.Different from the traditional tracking problem in WSN,using the static location-ware node to estimate the moving target,the mobile node is used to help unknown nodes to accurately discover their positions.A new node localization scheme virtual beacons-energy ratios localization(VB-ERL)and its refinements for the WSN are presented.In the scheme,the mobile node moves in the surveillant field based on the Gauss-Markov mobility model and periodically broadcasts the information packets.Each static unknown node receives the virtual beacons and energy in its sensing range,and estimates its location by finding the intersection of a set of hyper-spheres.Simulation results show the proposed scheme is efficient.
