狭长空间无线感知节点布置策略及定位算法

Study on Wireless Sensor Nodes' Layout Strategy and Localization Algorithm in the Long and Narrow Space

因为人们对无线感知节点在一些狭长空间场所的研究较少,受空间限制,无线感知节点及其网络在这些场所应用具有与开阔空间不同的特征,所以对目前应用于开阔环境下的无线感知节点定位算法进行了修正,给出了应用于狭长空间的无线感知节点定位算法。同时对狭长空间的锚节点布置方法进行了研究,给出一种较优的锚节点布置策略。理论分析、计算机仿真和实验验证表明:该算法及其锚节点布置策略在狭长空间应用中对未知节点具有很好的定位精度。

The wireless perception node localization algorithm is revised, this localization algorithm is used to open environment at present , and revised proposes algorithm is applied to a wireless perception node localization in long and narrow space. And the anchor node layout method of the long and narrow space is studied , a more optimal anchor node, layout strate~, is put forward in this article. Theoretical analysis, computer simulation and experiment show that the algorithm and its anchor node layout strategy has the very, good location accuracy in the long and narrow space application.
