Machine-to-Machine 통신 환경에서 무선측위를 이용한 영역 기반의 주파수 간섭 관리 기법

In an industrial environment, M2M (Machine-to-Machine) communication is an important method for controlling the machine. Especially, WSN(Wireless Sensor Network) is used for sensing the machine condition and communicating to human device. However, frequency interference is occurred in WSN since ZigBee, Bluetooth, and WLAN (Wireless Local Area Network) are using the same ISM (Industrial Science Medical) band. Therefore, we proposed a novel management scheme of frequency interference by using wireless localization.
