  2. Contents • Xbee Communication • Multi Hop Communication • 실습

  3. Mesh NetworkMulti Hop Communication Xbee Communication

  4. Mesh network • Xbee Series2 는 mesh network를 지원 한다. • Coordinator, Router, End device로 구성된다. • 하나의 네트워크에서는 coordinator는 하나만 존재한다. • Router의 역할은 End device와 coordinator를 연결 시켜준다. (end device와 coordinator와의 거리상 연결이 되지 못할 경우)

  5. 실습에 사용되는 xbeeseries 2 module 의 펌웨어는2종류이다. • Coordinator • Router/End Device • 1개의 Coordinator 와 다수의 Router/End Device로 네트워크를 구성한다.

  6. Mesh Network Coordinator Router End Device

  7. Mesh Network Coordinator Router/End Device

  8. Multi Hop Communication

  9. Multi-Hop Communication 도전과제

  10. 도전과제 • 온도, 조도, 습도 센서 값을 Multi-Hop 으로 전송하기 온도, 조도, 습도 센서 추가

  11. Thank You
