Study on ZigBee technology

Wireless Sensor Networks are being gradually introduced in different application scenarios. ZigBee is one of the most widely used transceiver standard in wireless sensor networks. ZigBee over IEEE 802.15.4., defines specifications for low data rate WPAN (LR-WPAN) to support low power monitoring and controlling devices. This paper presents a detailed study of Zigbee wireless standard, IEEE 802.15.4 specification, ZigBee device types, the protocol stack architecture and its applications.
