Abstract: Method for rapidly detecting identifier (ID) of tags, by radio frequency identification (RFID) reader in communication system that includes RFID reader and at least two tags communicating with RFID reader, is provided. RFID reader generates a prefix when IDs contained in at least two messages received collide with each other, prefix including a first colliding bit, which is set to ‘0’ or ‘1’, from high-order bits and non-colliding high-order bits. RFID reader sends a first message containing information that requests transmission of an assigned ID in a preset transmission period when the bits of the generated prefix match bits corresponding to the prefix, in the assigned ID. Tags receive a first message that contains a prefix including at least one bit, and sends a second message containing an assigned ID during a preset transmission period when the bits of the prefix match bits corresponding to the prefix, in assigned ID.

Abstract: A method and apparatus for a sensor network having a plurality of reference nodes and a sensor node that enables the sensor node to compute a relative position through transmission range control and position mapping. In transmission range control, each reference node sends location information signals to the sensor node while varying transmission power. In position mapping, the sensor node forms a grid of vertical and horizontal lines corresponding to a square area defined by the neighboring reference nodes, extracts coordinates of intersections in the grid belonging to a shared region between areas covered by location information signals of various transmit power levels from the neighboring reference nodes, and sets the position of the sensor node to the middle points of the extracted coordinates. Each reference node sends a location information signal when a random backoff time expires after reception of a location information request signal.

Abstract: A method for establishing a path between nodes in a wireless network system. A source node broadcasts a route request (RREQ) packet for a destination node. A mobile node between the source node and the destination node, upon receiving the RREQ packet, appends a redundancy degree with respect to an adjacent node to the RREQ packet and broadcasts the RREQ packet. The destination node selects an optimal path by checking the redundancy degree received along each path when the RREQ packet is received along multiple paths, and the destination node establishes an optimal path to the source node by transmitting a route reply (RREP) packet along the optimal path. Accordingly, the path is established suitable for the quality of service of data to be transmitted and a lost path is promptly recoverable by reference to information stored at each mobile node identifying redundant paths available to the mobile node.

Abstract translation: 一种用于在无线网络系统中的节点之间建立路径的方法。 源节点广播目的地节点的路由请求（RREQ）数据包。 在源节点和目的节点之间的移动节点在接收到RREQ分组后，将相邻节点的冗余度附加到RREQ分组并广播RREQ分组。 目的地节点通过检查在沿着多个路径接收到RREQ分组时沿着每个路径接收的冗余度来选择最优路径，并且目的地节点通过沿着最优路由发送路由应答（RREP）分组来建立到源节点的最佳路径 路径。 因此，建立适合于要发送的数据的服务质量的路径，并且可以通过参考存储在每个移动节点处的信息来迅速恢复丢失的路径，该信息标识可用于移动节点的冗余路径。
