Node and method for selecting parent node in ZigBee network, and method for measuring trust model of ZigBee network

摘要

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.
