Abstract: PURPOSE: A monitoring sensor network system and a control method are provided to supply a low power operation method and a communication protocol appropriate for a limited number of nodes, a wide arrangement interval between nodes, a requirement for a long operation time, etc. CONSTITUTION: A relay node(200) controls a short-distance wireless frequency state or a long-distance wireless frequency state for data transmission. The relay node receives detection information transmitted from a sensor node. The relay node transmits the received detection information. A C2 terminal(300) receives the detection information transmitted from the relay node. The C2 terminal analyzes the received detection information. The C2 terminal outputs an analyzed result.

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。
