Abstract: PURPOSE: A waiting time controlling method in consideration with packet size in a sensor network is provided to increase the performance of a data aggregation method in case data is compressed. CONSTITUTION: An initialization message is transmitted from a sink node to a sensor node. Data which is collected by the sensor node is transmitted to the sink node. The initialization message is received in order to control waiting time according to the number of data. The waiting time is controlled by Ti=MAX( hXg/q/cX(i-1)+g/q, 0 ).

Abstract: PURPOSE: A method for constructing a sensor network tree structure is provided to require minimum hardware and information, thereby constructing the tree structure of the sensor network at a lower cost. CONSTITUTION: When changing a sensor network, each node of the sensor network calculates a parent node score and parent node selection priority. According to the parent node selection priority, each node collects a parent node score from neighboring nodes(S210). The node transmits a parent node selection message to a node with a top parent node score(S220). A node which receives the message transmit a parent node confirmation message to the node(S240). The nodes register the opponent as a child node and a parent node(S253,S255).

Abstract: Disclosed is a polling list management method using orthogonal signaling in a wireless LAN including a plurality of terminals and a base station, the method comprising: a first step where the base station transmits a first and a second orthogonal code to the respective terminals, the orthogonal codes being unique for each terminal and "bit-wise inverse" of each other; a second step where the respective terminals having received the first and second orthogonal codes transmit one of the first and second orthogonal codes to the base station to request polling; and a third step where the base station determines whether the corresponding terminal should be polled, based on the received orthogonal code.

Abstract: PURPOSE: A multipath maintaining method using location information of a node is provided to maintain a route in a MANET and minimize an increase of a control message which maintains a route. CONSTITUTION: A source node(100) sets a multipath to a destination node(110). When one of route nodes on the multipath moves, a mobile node(200) calculates distance information between a first location and a second location. When the calculated distance is out of a preset transmission range, the mobile node selects a neighbor node(210) closest to the second location. The source node maintains a route to the destination node through the selected neighbor node.
Abstract translation: 目的：提供一种使用节点位置信息的多路径维护方法，以维护MANET中的路由，并最大限度地减少维护路由的控制消息的增加。 构成：源节点（100）设置到目的地节点（110）的多路径。 当多路径上的一个路由节点移动时，移动节点（200）计算第一位置和第二位置之间的距离信息。 当计算出的距离超出预设传输范围时，移动节点选择最靠近第二位置的邻居节点（210）。 源节点通过所选邻居节点维护到目的节点的路由。
