ZigBee technology was developed for special wireless networks where Bluetooth & wi-fi technologies are not showing better results. In wireless personal area networks (PAN) where we need to transmit low data rate information in comparatively large area (10-100 m). We can use Zigbee transceiver system instead of other technologies. As the functionality of Simplicity and Zigbee Technology is simil...

Teleca Systems AB has received several requests to develop wireless applications in areas where there are no suitable standardized solutions. They wish to examine if ZigBee, a new wireless industrial standard can be the answer to the demand for such networks. ZigBee is interesting since it is the first attempt to standardize low power, low data rate networks. The main objective of this Master’s...

OQPSK modulation technique is used for designing Zigbee transceiver worldwide since several years of invention of ZigBee technology. It provides good battery life, better range and various other advantages for which Zigbee technology is known. But here we are discussing about the transceiver performance over the noisy channel. In noisy channel, we are proposing MSK based Zigbee technology and c...

ZigBee is a new global standard for wireless communications with the characteristics of low-cost, low power consumption, and low data rate. It has a good market in wireless meter reading. The design and implementation of a ZigBee-based wireless automatic meter reading system are proposed in this paper. The experimental results show that the design can meet the basic needs of automatic meter rea...

One of the obstacles preventing the Zigbee protocol from being widely used is the excessive power consumption of Zigbee devices in low bandwidth and low power requirement applications. This paper proposes a protocol that resolves the power efficiency problem. The proposed protocol reduces the power consumption of Zigbee devices in beacon-enabled networks without increasing the time taken by Zig...

In the present existing system, only Zigbee is used as a wireless communication device to transmit the sensed data to the control room through commercial platform Zigbee. A new system is presented in which the application of WSN (Wireless Sensor Network)/Zigbee is gaining popularity and connecting WSN/Zigbee to the present standard network seamlessly is an important issue. This paper presents t...

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:...
