Zigbee Technology

Abstract

This paper aims at presenting the concept of ZigBee, the name of a specification for a suite of high level communication protocols using small, low - power digital radios based on the IEEE802.15.4 - 2006 standard for wireless personal area networks (WPANs),such as wireless headphones connecting with cell phones via short - range radio. The technology is intended to be simpler and less expensive than other WPANs, such as Bluetooth. ZigBee is targeted at radio - frequency (RF) applications that require a low data rate, long battery life, and secure networking. The ZigBee communication is a communication technology to connect local wireless nodes and provides high stability an d transfer rate due to data communication with low power. In the nodes away from coordinator in one PAN, the signal strength is weak causing the net work a shortage of low performance and inefficient use of resources due to transferring delay and increasing delay time and thus cannot conduct seamless communication
