%X <p>In wireless sensor networks, the localization of nodes is vital and promising to a wide scope of applications. Based on characteristics of DV-hop, an improved algorithm for the typical range-free localization was proposed. The main principle of the improved algorithm is to introduce hop coefficient to revision hops, which could address the problem that DV-hop localization of wireless sensor networks produces error of hops stimulation. Then hop coefficient could bring down the error of per hop average distances and be sure precisely unknown nodes and reference node. Simulation demonstrates that the results of improved algorithm are more accurate, and the errors down to about 10%.</p>
