Abstract
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.
INTRODUCTION
Wireless Technology is being developed rapidly
nowadays. Advancement in microelectromechanical systems
brings integration of sensing, signal processing and RF
capability on very small devices. All kind of portable
applications tend to be able to communicate without the use
of any wires. Aim of wireless communication is to gather
information or perform certain task in the environment. A
typical sensor node contains three C’s, are Collection,
Computation and Communication units. Based on the
request of sink, gathered information will be transmitted
wirelessly. The collection unit has series of sensors.
Computation unit contains microcontroller and memory.
Finally the communication unit contains transceiver to
transmit and receive data; various transceivers (such as RFM
TR1000 family, Hardware accelerators, Chipcon CC1000
and CC2420 family , In
