Zigbee operates in the industrial, scientific and medical radio bands; 868 MHz in Europe, 915 MHz in countries such as USA and Australia and 2.4 GHz in most jurisdictions worldwide. The technology is intented to be simpler and less expensive than other WPANS such as bluetooth. Radios are also avaiable stand lone to be used with any processor or microcontroller.

4. INTRODUCTION
Zigbee operates in the
industrial, scientific and medical radio
bands; 868 MHz in Europe, 915 MHz in
countries such as USA and Australia and
2.4 GHz in most jurisdictions worldwide.
The technology is intented to be simpler
and less expensive than other WPANS
such as bluetooth. Radios are also
avaiable stand lone to be used with any
processor or microcontroller.

5. HISTORY
Zigbee technology was at the year 1998.
In summer of 2003,Philips semiconducters, a major
mesh network supporter, ceased the investment.
The zigbee specifications were ratified on 14th december
2004.
The zigbee alliance announces public availability on 13th
June 2005, known as zigbee 2004 specification.
During the last quarter of 2007,zigbee PRO, the
enhanced zigbee specification was finalized .

7. HOW ZIGBEE WORKS ?
Zigbee uses digital radios to allow devices to
communicate with another .A network coordinator
is a device that set’s up the network ,is aware of all
the Nodes within its network ,and manages
both the information about each node as well as
the information that is being transmitted within
the network.Several topologies are supported by zigbee
tech. including star , mesh and cluster Tree .Star
topology is most useful when several and devices are
located closed together.

Zigbee router (ZR)
Zigbee coordinator (ZC)
Zigbee end device (ZED)

9. Advantages
Zigbee is low cost which allows the
technology to be widely deployed in wire
less control.
Zigbee has low power usage allows longer
life with smaller batteries .
It has mesh networking which provides
high reliability and large range.

10. Applications
Home automation
Zigbee smart energy
Telecommunication applications
Personal home and hospital care

11. Conclusion
In this way ,an academic
research group has examined the
Zigbee address formation algorithm in
the 2006 specification and argues that
the network will isolate many units that
could be connected .The group
proposed an alternative algorithm with
similar complexity in time and space .
