Transcript

  • 1. ZIGBEE TECHNOLOGY Hardeep SinghUnder the guidance of: Roll No.-123abc School of Electronics & communication engineering Lovely Professional University Phagwara, Punjab-144401
  • 2. The ZigBee Name•Named for erratic, zigzagging patterns ofbees between flowers•Symbolizes communication between nodes ina mesh network•Network components analogous to queenbee, drones, worker bees
  • 3. What is ZigBee?•Technological Standard Created forControl and Sensor Networks•Based on the IEEE 802.15.4 Standard•Created by the ZigBee Alliance
  • 4. Research on Zigbee•The IEEE standard 802.15.4 was completed inMay 2003.•The zigbee specifications were ratified on 14December 2004.•The zigbee alliance announced public availabilityon 13 June 2005.•Much research is still going on with zigbee.
  • 5. Sensor/Control Network Requirements 1.Large networks that can form autonomously and that will operate very reliably for years. 2.Very long battery life. 3.Very low infrastructure cost 4.Less complexity and small size 5.Device data rate are low
  • 6. Why Zigbee?ReliableMesh networkingLow data-rate applicationsVery long battery lifeSecureScalableLow costGlobal application
  • 7. How Does Zigbee Work?1.It works on digital radio networks via direct- sequence spread spectrum coding.2.Operate on ISM band.3.ZigBee-compliant radios may operate on one of three different radio bands: the 868 MHz,2.4GHz or 5.8 GHz frequencies.
  • 8. Zigbee - NetworkThere are three logical device types in a ZigBee network – (i) Coordinator (ii) Router and (iii) End-device.
  • 9. Zigbee – Network(cont.)(i) Coordinator• This is the device that “starts” a ZigBee network.• It is the first device on the network.• The coordinator node chooses a channel and a network identifier and then starts the network.
  • 10. Zigbee – Network(cont.)(ii) Router• allows other devices to join the network• multi-hop routing
  • 11. Zigbee – Network(cont.)(iii) End Device• An end-device has no specific responsibility for maintaining the network infrastructure, so it can sleep and wake up as it is chosen.• Generally, the memory requirements are lower for an end-device.
  • 12. ZigBee Network Configuration
  • 13. ZigBee Mesh Networking
  • 14. ZigBee Mesh Networking
  • 15. ZigBee Mesh Networking
  • 16. ZigBee Mesh Networking
  • 17. ZigBee Mesh Networking
  • 18. WIRELESS TECHNOLOGY COMPARISON CHARTStandard Bandwidth Protocol Stack Stronghold Applications SizeZigBee 250kbps 4-32KB Long battery life, Remote control, low cost battery-operated products, sensorsBluetooth 1 Mbps ~100+KB cable replacement Wireless USB, handset, headsetWi-Fi Up to 54Mbps 100+KB High data range Internet browsing, PC networking, file transfers

  • 20. ZigBee’s Future
  • 21. Zigbee Alliance - Members and many more....
  • 22. ConclusionIn future all devices and their controls will be based on this standard. Since Wireless personal Area Networking applies not only to household devices, but also to individualized office automation applications, ZigBee is here to stay. It is more than likely the basis of future home networking solutions………
  • 23. Parting Thought“Just as the personal computer was a symbol ofthe 80s, and the symbol of the 90s is the WorldWide Web, the next nonlinear shift, is going to bethe advent of cheap sensors.”Paul SaffoInstitute for the Future
