3. The ZigBee Name Named for erratic, zig-zagging patterns of bees between flowers Symbolizes communication between nodes in a mesh network Network components analogous to queen bee, drones, worker bees

4. What is ZigBee? Technological Standard Created for Control and Sensor Networks Based on the IEEE 802.15.4 Standard Created by the ZigBee Alliance

5. introduction Zigbee is specification for high level communication protocols using small. The IEEE 802.15.4 standard was completed in May 2003. The ZigBee specifications were ratified on 14 December 2004. The ZigBee Alliance announced public availability of Specification 1.0 on 13 June 2005 Much research is still going on with ZigBee.

6. ZigBee uses It is used for embedded application for low data rates and Low power consumption, In expensive Small packet networks Home Entertainment and Control Wireless sensor network’s
