| 摘 要： | 针对Dv—hop算法存在的网络通信开销大和远近参考节点对定位精度影响不同的问题，提出了逐级分区加权算法，此算法通过对参考节点进行分级并对不同参考节点赋予不同的权重，解决了原算法中存在的问题。而且通过Omnet＋＋和Matlab仿真软件对此算法进行验证，表明在传感器网络分布极不均匀时，逐级分区加权算法更具有优势。

| Abstract: | There are two problems of Dv-hop, which are high communication coat of the network and different anchor＇s affect by different distance of anchors. An improved arithmetic is brought forward in this paper in which a leveled flooding method and a hop weighted hopsize calculation method are adopted. The new arithmetic not only reduces the communication coat of the network greatly, but also reduce the far anchor＇s affect much more. And the new arithmetic is proved by simulation with Omnet＋＋ and Matlab,which proves this choosing policy is more reasonable, es- pecially in anisotropic networks. |
