ZigBee was developed by IEEE 802. 15. 4 Task Group and ZigBee Alliance. ZigBee (IEEE 802. 15. 4?2006 standard) is a category in the IEEE 802 family and ZigBee alliance is responsible for ZigBee standard which uses the transported services of the 802. 15. 4 network specification therefore ZigBee is a specification for a suite of high level communication protocols using small, low-power digital r...

Nowadays, wireless communication has a great advantage in technology. We use wireless devices almost in all expected life such as: entertainment, working and recently in the healthcare area, where Wireless Body Area Networks (WBANs) become a hot topic for researchers and system designers. Recent work on WBANs focus on related issues to communication protocol, especially ZigBee network is fine t...

This paper proposes a device discovery method for consolidated IP and ZigBee home networks. The method broadcasts an IP multicasted device discovery request of UPnP, m-search, in the ZigBee network as a Constrained Application Protocol (CoAP) message. Upon receiving the m-search broadcast, ZigBee devices respond after a constant time delay with their device description Universal Resource Name (...

the authors developed user recognition system for navigation robot. This system is used to prevent navigation robot mistaking user. It uses ZigBee-3D acceleration sensor and kinect sensor. The ZigBee coordinator which is mounted navigation robot know that user comes near to navigation robot by finding the ZigBee accelerometer tag which is attached a user. This tag has unique ID each other, so t...

Zigbee is one of the major sources of interference in 2.4GHz band for WLANs. It is seen whenever any Zigbee system is operating near to the WLAN system and transmitting signal at same frequency, time as of WLAN’s, the later ones performance detoriate severely. So in this paper an algorithm is proposed to estimate Zigbee interference component present in all OFDM based WLANs sub-carriers and can...

At present, the research on the technology of mobile robot navigation is under the spotlight. This paper introduces ZigBee technology into mobile robot’s research, and constructs an experimental system for robot navigation based on ZigBee wireless sensor network localization technology. In this system, robot added a ZigBee module takes the position as a blind node in ZigBee network, which forms...

A software defined ZigBee receiver has been designed, implemented and tested with a commercially available offthe-shelf ZigBee transceiver. This system is based on the software defined system-in-package (SIP) platform by Harris Corporation (Melbourne, Florida, USA). This platform is equipped with a high-resolution analog-to-digital converter (ADC) and four Xilinx Virtex-4 FPGAs. An alldigital p...

In this paper we have designed and developed ZigBee network in real time using ZigBee nodes to monitor risky parameters such as temperature, pressure, toxic gases and other chemical substances. Discussed about Wireless Sensor Network (WSN), ZigBee, ZigBee Network, Protocol stack and its various Applications. Derived various results from the network created. Various characteristics and network p...

Description This document introduces all kinds of 2.4GHz RF products. It focuses on analysis of ZigBee ® and other 2.4GHz RF products and concludes on the interferences with ZigBee and ZigBee's coexistence possibility with other 2.4GHz RF products in the same space. The document will help to make ZigBee work well under the complex electromagnetic environment.

The deployment of ZigBee networks is expected to facilitate numerous applications, such as home healthcare, medical monitoring, consumer electronics, and environmental sensors. For many envisioned applications, device mobility is unavoidable and must be accommodated. Therefore, providing ubiquitous connection to/from a mobile ZigBee device is crucial for future ZigBee applications. In particula...
