| 摘 要： | 提出一种与距离无关的基于移动坐标系的分布式定位算法,以移动锚节点为原点建立坐标系,未知节点以邻居锚节点信息在临时坐标系中确定自身位置区域,通过在不同坐标系下确定的位置区域取公共集不断缩小自身未知区域,最后利用质心算法求出节点位置坐标。仿真结果表明:新算法拥有较高的定位精度和适度的开销。

| Abstract: | A distributed node localization algorithm based on mobile coordinate systems is presented.It is irrelevant to distance.The moving anchor node is set as the origin to build the coordinate system,while unknown nodes counting on the neighboring anchor nodes to locate itself in the temporary coordinate system.Unknown region of itself is continuously narrowed by finding the public set that picked in the certain location of different coordinate systems.By the centroid algorithm,the location coordinate of unknown ... |
