WIRELESS SENSOR NETWORK USING ZIGBEE

Abstract

A wireless sensor network (WSN) consists of sensors which are densely distributed to monitor physical or environmental conditions, such as temperature, sound, pressure, etc.The sensor data is transmitted to network coordinator which is heart of the wireless personal area network.In the modern scenario wireless networks contains sensors as well as actuators.ZigBee is newly developed technology that works on IEEE standard 802.15.4,which can be used in the wireless sensor network (WSN).The low data rates, low power consumption, low cost are main features of ZigBee.WSN is composed of ZigBee coordinator (network coordinator), ZigBee router and ZigBee end device.The sensor nodes information in the network will be sent to the coordinator, the coordinator collects sensor data, stores the data in memory, process the data, and route the data to appropriate node.
