  • 2. introduction
    What is zigbee
    Difference between zigbee with othere WSN .
    Application
    Architecture
  • 3. What is ZigBee?
    Technological Standard Created for Control and Sensor Networks
    Based on the IEEE 802.15.4 Standard
    Created by the ZigBee Alliance
  • 4. Why do we care
    • Zigbee touches the kinetic world more than any other wirless packet technology.
    • 5. Wifi does not control water spill gate at dam
    • 6. Bluetooth does not control lighting ,HVAC and application in your office or home.
    • 7. Manupulating the physical world through wirlessintroduces newrisks.
    • 8. Many of the past mistake is repeat again.

  • 16. Zigbee - Overview
    1. A ZigBee network is a multi-hop network with battery-powered devices.2. The set of networking functions that a device performs determines the role of the device in the network and is called a device type.3.The set of parameters that need to be configured to specific values, along with those values, is called a stack profile.4.There are three logical device types in a ZigBee network –(i) Coordinator(ii) Router and(iii) End-device.
  • 17. Zigbee - Overview
    (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 ( also called PAN ID ) and then starts the network.
  • 18. Zigbee - Overview
    (ii) Router
    • A Router performs functions for
    (i) allowing other devices to join the network
    (ii) multi-hop routing
  • 19. Zigbee - Overview
    (iii) End Device
    • An end-device has no specific responsibility for maintaining the network
    infrastructure, so it can sleep and wake up as it chooses.
    • Thus it can be a battery-powered node.
    • Generally, the memory requirements (especially RAM requirements) are lower for an end-device.
