Due to low cost, low-power, and scalability, ZigBee is considered an efficient wireless AMR infrastructure. However, these characteristics of ZigBee can make the devices more vulnerable to unexpected error environments. In this paper, a fault-tolerant wireless AMR network (FWAMR) is proposed, which is designed to improve the robustness of the conventional ZigBee-based AMR systems by coping well...

IEEE 802.15.4 (Zigbee) is a leading technology for wireless sensor network, it is a medium access control and physical layer standard specially designed for short range wireless communication. Zigbee is used in applications that require low rate, secure networking, low complexity and power saving consumption. Generally Zigbee is typically used for environmental monitoring applications such as r...

ZigBee is a robust wireless communication standard managed by the ZigBee Alliance and based on the standard IEEE 802.15.4 physical and MAC layers. Certain applications of ZigBee, may be critically limited by its designation as a low data rate standard. This paper describes a three-phased approach for measuring and attaining maximal throughput in a ZigBee wireless network. The phases consist of:...

Increased demands on implementation of wireless sensor networks in automation praxis result in relatively new wireless standard – ZigBee. The new workplace was established on the Department of Electronics and Multimedia Communications (DEMC) in order to keep up with ZigBee modern trend. This paper presents the first results and experiences associated with ZigBee based wireless sensor networking...

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...
