INTRODUCTION

• Technological standard created for control and
  sensor networks,
• Based on the IEEE 802.15.4 standard. it can
  provide the wireless personal area network.
• ZigBee specification is to be simpler and less
  expensive compare with the other WPN's such as
  Bluetooth.
• Designed for low power consumption allowing
  batteries to essentially last for ever.

• ARCHITECTURE OF ZIGBEE

• ZigBee architecture is a combination of 6 layers.
  
• Application Layer
• Application Interface Layer
• Security Layer
• Network Layer
• Medium Access Control Layer
• Physical Layer

TYPES OF ZIGBEE DEVICES

• There are three different ZigBee device types
  that operate on the layers in any self-organizing
  application network
• Zigbee Coordinator
• Zigbee End Device (ZED)
• Zigbee Router(ZR)

• NETWORK TOPOLOGIES

• The number of routers .coordinators and end
  devices depends on the type of network such as
• Star Topology
• Mesh Topology
• Cluster tree Topology

ADVANTAGES OF ZIGBEE NETWORK

• Advantages of Zigbee networks
• Zigbee has a flexible network structure
• It has very long battery life
• Zigbee has a mesh network topology with low cost,
  multi hope data transmission and is power
  effective
• It is less complex than Bluetooth
• It is easy to install
• Zigbee support a large number of nodes
• Zigbee is more reliable
• It is a short working period result in power
  saving and power consumption of communication

DISADVANTAGES OF ZIGBEE NETWORK

• Disadvantages of Zigbee networks
• Zigbee disadvantages mainly include short range
• Low complexity, and low data speed
• Its high maintenance cost, lack of total
  solution, and slow materialization,
• Low transmission, as well as low network
  stability, are also some of its disadvantages
  that takes it a step back as compared to others
• Replacement with Zigbee compliant appliances can
  be costly
• Zigbee is not secure like WiFi based secured
  system
• It does not have end devices available yet

CHARACTERISTICS OF ZIGBEE

• General Characteristics of Zigbee Standard
• Low Power Consumption
• Low Data Rate (20- 250 kbps)
• Short-Range (75-100 meters)
• Network Join Time ( 30 msec)
• Support Small and Large Networks (up to 65000
  devices (Theory) 240 devices (Practically))
• Low Cost of Products and Cheap Implementation
  (Open Source Protocol)

APPLICATIONS OF ZIGBEE

• The ZigBee Alliance targets applications Across
  consumer, commercial, industrial and government
  markets worldwide
• Home networking
• Industrial control and management
• Medical Data Collection

CONCLUSION
In future all devices and their controls will be
based on this standard. Since Wireless Personal
Area networking applies not only to house hold
devices, but also individualized office
automation application , zigBee is here stay it
is more than likely the basis of future home
networking solution.
