Abstract: 본발명의특징은위치인식정확도를높이기위해집중형위치인식기법인 MDS 알고리즘을사용하며, MDS 알고리즘사용시모든노드에대해 MDS 알고리즘을일괄수행하는대신앵커노드3개와위치계산이필요한노드를하나씩추가하면서전체노드에대해위치인식을반복적으로수행함으로써, 센서노드간의위치를정확히계산하고, MDS 알고리즘의계산의복잡도를감소시켜위치인식계산수행시간을단축시킨다.

Abstract: PURPOSE: A location calculating method between sensor nodes is provided to reduce an error of a location recognition generated by performing MDS algorithm. CONSTITUTION: A sync node or a server repetitively performs a MDS algorithm(S4). The sync node or the server obtains a relative coordinate of nodes. The sync node or the server changes the obtained relative coordinate of the nodes into an absolute coordinate(S5). The sync node retransforms the changed absolute coordinate into a WGS84 coordinate system(S7). The sync node obtains the absolute coordinate of the nodes in a cluster.
Abstract translation: 目的:提供传感器节点之间的位置计算方法,以减少通过执行MDS算法生成的位置识别错误。 构成:同步节点或服务器重复执行MDS算法(S4)。 同步节点或服务器获取节点的相对坐标。 同步节点或服务器将获得的节点相对坐标改变为绝对坐标(S5)。 同步节点将改变的绝对坐标重新转换为WGS84坐标系(S7)。 同步节点获取集群中节点的绝对坐标。
