Abstract: PURPOSE: A node of a zigbee network for the selection of a parent node, a method for parent node selection, and a reliability model measurement method of the zigbee network are provided to differently apply a reliability model to network configuration according to the installation location of a sensor node and the design of a node. CONSTITUTION: A communication unit(140) receives each reliability model of neighbor nodes from the neighbor node. Using a received reliability model, a parent node selecting unit(150) selects one of the neighbor node as a parent node. The parent node selecting unit selects a plurality of candidate parent nodes with an LQI(Link Quality Indicator) and hop for the each neighbor node. The parent node selecting unit selects a node having the greatest reliability of the candidate parent node as the parent node.

Abstract: PURPOSE: A system and a method for preventing the occurrence of a missing child are provided to continuously check a distance between a location transmitter and a location receiver, thereby preventing a situation of a ward to be a missing child in advance. CONSTITUTION: A location transmitter(10) periodically sends a location signal. A location receiver(20) receives the location signal and determines spaced distance with the location transmitter. If the spaced distance escapes the preset range, the location receiver generates an alarm signal. The location transmitter and the location receiver directly exchanges signals wirelessly in a close distance. The location transmitter is mounted to a mobile phone of a guardian.

Abstract: PURPOSE: A method and system for pursuing a lost child are provided to supply the location of a lost child and save system building costs and operation costs. CONSTITUTION: A lost child pursuing system(100) comprises end devices(110,111), a first coordinator(120), and a second coordinator(121). The end devices operate an end device of a zigbee protocol. A child has the end device. The first coordinator and an end device make a pair and function as a coordinator of a zigbee protocol. Parents have the first coordinator and the end device. The remaining protector except the first protector has the second coordinator. The end devices participate in a network that the second coordinator forms when the communication between the first coordinator and the end devices is disconnected.
