SHOW CASE MANAGEMENT SYSTEM USING USN

摘要

A show case management system using a USN(Ubiquitous Sensor Network) is provided to quickly manage a show case by uniformly maintaining information communication speed when a show case is at a remote place. Sensor nodes compose a sensor network. The sensor node receives state information from show cases. The sensor node transmits inputted state information by radio wave intensity influencing the entire sensor network. A management server(150) directly receives state information from the sensor node in the sensor network. The management server produces management information based on the received state information. The management server outputs the state information and management information.
