Range-free Synthesized Localization Algorithm Based on WSN
无需测距的综合节点定位算法

This paper applies a new modified Synthesized algorithm based on the ill-natured nodes which produced by the primary DV-Hop nodes localization algorithms and the weakness of accumulated error brought by the multi-level jumps.It is that Centroid and DV-Hop Localization Synthesized.The algorithm helps to lower the hardware overhead so as to fix an accurate position.Improve the algorithm of positioning error rate after the positioning before than improved significantly less error rate,showed the positioning error rate increased with anchor the number of node is decreased.It checks the errors of the node localization by simulation verification through the MATLAB software,which also proves that the algorithm itself is stable and reliable,easily to carry out.Improved positioning accuracy reduces the energy congumption level,achieves the expected goal.
