Zigbee is a unique communication standard designed for low-rate wireless personal area networks. It having extremely low complexity and low amount of cost and power consumption for wireless connectivity in inexpensive, convenient and mobile devices. In Zigbee networks, a tree construction is often used to construct a wireless sensor network for data delivery applications. However, data delivery...

ZigBee technology as a wireless sensor and control network is one of the most popularly deployed wireless technologies in recent years. This is because ZigBee is an open standard lightweight, low-cost, low-speed, low-power protocol that allows true operability between systems. It is built on existing IEEE 802.15.4 protocol and therefore combines the IEEE 802.15.4 features and newly added featur...

Based on the ZigBee networking technology and protocol analysis, The paper designs a ZigBee Network Model with the features of communication and location which mainly rests on CC2431 ZigBee network location property and further propose a mobile electronic supermarket shopping guide system which can locate expected goods , navigation and offer the latest information on supermarket product.

The industrial Internet of Things (IoT) is aiming to interconnect humans, machines, materials, processes and services in a network. Wireless Sensor Network (WSN) comprises the less power consuming, light weight and effective Sensor Nodes (SNs) for higher network performance. Radio Frequency Identification (RFID) and sensor networks are both wireless technologies that provide limitless future po...

A cost effective ZigBee based wireless mine supervising system with voice over ZigBee (VoZ) is presented here. Here we design a smart helmet, which enable the helmet as a mobile sensor node of ZigBee wireless sensor networks, gathering parameters the temperature, humidity and illumination level of underground environment and will alert the central management unit in case of abnormal condition. ...

ZigBee is a fairly new but promising wireless sensor network standard that offers the advantages of simple and low resource communication. Nevertheless, security is of great concern to ZigBee, and enhancements are prescribed in the latest ZigBee specification: ZigBee-2007. In this technical report, we identify an important gap in the specification on key updates, and present a methodology for d...

In this paper, we develop wireless optical monitoring system using ZigBee network and Fiber Bragg Grating (FBG) sensor. FBG sensors are manufactured using the 248nm excimer laser and phase masks. The adopted wireless networking between PC and FBG interrogator is ZigBee, because ZigBee is a specification for a suite of high level communication protocols using small, low-power digital radios base...

With the rapid development of wireless technologies, it is possible for Chinese automatic meter reading system (AMRS) to be equipped with wireless sensor networks due to their low-cost, simplicity and mobility. In the current study, we compared the advantages of ZigBee with other two similar wireless networking protocols, Wi-Fi and Bluetooth, and proposed a wireless solution for AMRS based on Z...

Public Addressing System (PA) is an electronic sound and amplification distribution system with a microphone, amplifier and loudspeakers. PA systems are widely used to make announcements in public, institutional and commercial buildings and locations .In PA systems cost, quality and expansion are the major factors that affect the working and implementation of the system. The Zigbee based monito...
