An Improved WC-RDV Localization Algorithm for WSNs

As a classic localization algorithm for WSNs (Wireless Sensor Networks), DV-hop is widely used due to its simplicity but its accuracy is less satisfying. In this paper, we have delved deeply into the algorithm details of the original DV-hop and investigated the reasons behind its high error rate. We then proposed an Improved Weighted Centroid RDV-hop (Improved WC-RDV) algorithm, which combines the Improved Weighted Centroid algorithm and Improved RDV-hop algorithm. Simulations also have been conducted and the results confirm that our Improved WC-RDV performs much better than several other DV-hop localization algorithms.
