Energy efficiency and network lifetime are main concerns in WSN. In order to improve these factors ZigBee plays an important role. Low cost, low data rate features of ZigBee results in low power consumption and makes it useful in wireless sensor networks, increasing life of small batteries of nodes in the network. Since tree routing in ZigBee does not require any routing tables to send the pack...

Wireless networks have been an essential part of communication in our daily life. Targeted at different applications, a variety of wireless networks have emerged. Due to constrained resources for wireless communications, challenges arise but are not fully addressed. Featured by low cost and low power, ZigBee technology has been developed for years. As the ZigBee technology becomes more and more...

The zigbee tree routing is wide used in several resource restricted devices and applications. Since it doesn’t need any routing table and route discovery overhead to send a packet to the destination. But the ZigBee tree routing has the elemental limitation that a packet follows the tree topology. Therefore, it cannot provide the optimum routing path. The shortcut tree routing protocol that prov...

Recently wireless sensor Network (WSN) and wireless personal area network (WPAN) has gained lot of interest from the research community because of its diverse applications of controlling, monitoring and automation of home, offices or any rescue area. Zigbee based on IEEE 802.15.4 standard is key enabling technology for the success of both WSN and WPAN. Zigbee has some inherent powerful characte...

Received Aug 9, 2017 Revised Nov 25, 2017 Accepted Dec 16, 2017 Zigbee is fastidious for a group of abnormal state communication conventions. Zigbee is a run of the mill remote correspondence innovation. ZigBee uses low rate, low-control advanced radios taking into account an IEEE 802 standard for individual region systems. The change characterised by the ZigBee particular is proposed to be eas...

A Zigbee and Bluetooth converter is designed in this paper. A multi-sinks wireless sensor network is used to solve the notable problems appeared in the single node wireless sensor network. These problems are solved in converter system such as data transmission reliability and node energy consumption imbalance and so on. The converter system can be better adapted to the large-scale, high-density...

ZigBee-style networks began to be conceived around 1999, when many installers realized that both Wi-Fi and Bluetooth were going to be unsuitable for many applications. In particular, many engineers saw a need for selforganizing ad-hoc digital radio networks. The real need for mesh has been cast in doubt since that, in particular as mesh is largely absent in the market. The fir stack release is ...

This paper is concerned with an intelligent application of Moving Picture Expert Group (MPEG) video transmission over IEEE 802.15.4 – ZigBee. MPEG Variable Bit Rate (VBR) video is data hungry and presents excessive time delay and data loss over a wireless communication. Conventional rate policing such as generic cell rate algorithm is inadequate to sufficiently regulate transmission of VBR data...

Devices are becoming increasingly interconnected; linked with each other and with humans. The internet of things(IoT) concept is currently used in machine to machine (M2M) applications like power, gas, and oil utilities transmission and transport. The most profound challenge that IoT faces is how to connect several very different devices into a network of things. In this regard, the standard fo...

To overcome the limitations of InfraRed (IR) remote control technology, ZigBee® RF4CE specification was first published in May 2009. It quickly became the dominant core technology that drives development of next generation remote control applications. ZigBee RF4CE technology uses IEEE 802.15.4 as its PHYsical (PHY) and Medium Access Control (MAC) layers, and builds network layer on top of them....
