Zigbee is a wireless technology standard used for control and sensor networks. It uses low power digital radios based on the IEEE 802.15.4 standard for wireless personal area networks (WPANs). Zigbee networks self-organize and can relay data through multiple nodes to remotely control electronic devices like lights, thermostats and appliances. The technology uses three types of devices - coordinators, routers and end devices - and can operate using star, tree or mesh network topologies to connect thousands of devices together. Zigbee is expected to be widely used for home automation and other Internet of Things applications in the coming years.

Conclusion INTRODUCTION •Technological Standard Created for Control and Sensor Networks •Based on the IEEE 802.15.4 Standard •High level Communication •Wireless Personal Area Networks (WPANs) •Created by the ZigBee Alliance HISTORY ZigBee-style networks began to be conceived about 1998, when many engineers realized that both WiFi and Bluetooth were going to be unsuitable for many applications. In particular, many engineers saw a need for self-organizing ad- hoc digital radio networks. The IEEE 802.15.4 standard was completed in May 2003. The ZigBee specifications were ratified on 14 December 2004. The ZigBee Alliance announces public availability of Specification 1.0 on 13 June 2005. DEVICE TYPES There are three different types of ZigBee device:
ZigBee coordinator (ZC)
ZigBee Router (ZR) ZigBee End Device (ZED) TYPES EXPLAINED…
ZigBee coordinator (ZC): The most capable device, the
coordinator forms the root of the network tree and might bridge to other networks.
There is exactly one ZigBee coordinator in each
network. It is able to store information about the network, including acting as the repository for security keys. TYPES EXPLAINED…
ZigBee Router (ZR): Routers can act as an intermediate
router, passing data from other devices.
ZigBee End Device (ZED): Contains just enough
functionality to talk to its parent node (either the coordinator or a router); it cannot relay data from other devices. It requires the least amount of memory, and therefore can be less expensive to manufacture than a ZR or ZC. ZIGBEE HOME AUTOMATION EXAMPLE WHAT DOES ZIGBEE DO
oOperates in Personal Area Networks (PANs) and device-
to-device networks
oConnectivity between small packet devices
oControl of lights, switches, thermostats, appliances, etc.
o Designed for wireless controls and sensors
HOW ZIGBEE WORKS
Topology Star Cluster Tree Mesh
Network coordinator, routers, end devices
TOPOLOGIES Different topologies as illustrated below: star, tree and mesh LAYERS OF ZIGBEE NETWORK:
Network and Application Support layer
Physical (PHY) layer
Media access control (MAC) layer
ZIGBEE PROTOCOL STACK USES In all of its uses, zigbee offers four inherent, beneficial characteristics: oLow cost oRange and obstruction issue avoidance oMultisource products oLow power consumption FUTURE OF ZIGBEE: A recent analyst report issued by West Technology Research Solutions estimates that by the year 2008, "annual shipments for ZigBee chipsets into the home automation segment alone will exceed 339 million units," and will show up in "light switches, fire and smoke detectors, thermostats, appliances in the kitchen, video and audio remote controls, landscaping, and security systems."
Futurists are sure to hold ZigBee up and say, "See, I told
you so". CONCLUSION
ZigBee is one of the global standards of
communication protocol formulated by the relevant task force.
ZigBee is the newest and provides specifications for
devices that have low data rates, consume very low power and are thus characterized by long battery life.
