Extracting Topology Preserving Maps Layout from Virtual Coordinates in Wireless Sensor Networks

The main objective of this project is 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.
