ZigBee: A Review

Past several years have witnessed a rapid development in the wireless network area. So far wireless networking has been focused on high-speed and long range applications. However, there are many wireless monitoring and control applications for industrial and home environments which require longer battery life, lower data rates and less complexity than those from existing standards. For such wireless applications a new standard called ZigBee has been developed by the ZigBee Alliance. ZigBee is a technological standard created for Control and sensor networks. It is based on the IEEE 802.15.4 standard. The IEEE 802.15.4 standard specifies the PHY Layer and MAC Layer for low data rate wireless PANs. This paper includes ZigBee Alliance, IEEE 802.15.4 model, applications and advantages of ZigBee, future scope of ZigBee.
