In this paper, the authors obtaining Topology-Preserving Maps (TPMs) from Virtual Coordinates (VCs) of wireless sensor networks. Virtual Coordinates (VCs) provide an economical alternative to geographical coordinates for routing and self organization of large-scale Wireless Sensor Networks (WSNs). This project proposes the TPM from the virtual co-ordinates. In a Virtual Coordinate System (VCS), a node is identified by a vector containing its distances, in hops, to a small subset of nodes called anchors. And extract the virtual co-ordinates. Topology coordinates provide an economical alternative to physical coordinates for many sensor networking algorithms.
