U-SCHOOL ZONE SERVICE BY BEACON ENABLED ENERGY EFFICIENT MESH NETWORK TECHNOLOGY

摘要

PURPOSE: A U(Ubiquitous)-school zone service using a beacon-based power-saving mesh network technology is provided to enable a guardian to watch a general school days of a child by providing U-school zone service using a USN(Ubiquitous Sensor Network) technology. CONSTITUTION: Each building data is collected, and transmitted to an integrated management center. The integrated management center collects all data. USN networks are installed classrooms, and corridors. Through a multi-hop communication, a portable terminal information of a child is transmitted to a gateway at the first floor. The gateway transmits the information to a building where the integrated management center is located through a wired network.
