This paper describes the experiments which have been conducted to determine the optimal implementation concept for AES (Advanced Encryption Standard) data encryption in a ZigBee network [1,2]. Two concepts have been considered. The first one is a AES128-CBC hardware co-processor embedded on a Spartan 3A FPGA. The second configuration implements the same cryptographic algorithm on the processor ...

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 IEEE 802.15.4, ZigBee is developed for low-power and low-data-rate wireless communication and it is building up remarkable position for wireless sensor network (WSN). As ZigBee is using the 2.4GHz Industrial, Scientific, and Medical (ISM) unlicensed frequency band, coexistence issues arise as there are also other wireless technologies sharing the same band, such as 802.11b/g WiFi, Blue...

Background Ofcom is currently examining the potential uses of the 2300 – 2400 MHz frequency band that is being released by the Ministry of Defence in the United Kingdom. Given the rising demand for broadband communications, one possible use is to support LTE systems in a time division duplex (TDD) arrangement. The band is directly adjacent to the unlicensed 2.4 GHz industrial, scientific and me...

In view of the poor initialization performance ecological environment monitoring network node location, a method location based on Zigbee is proposed. The data collection model built Zigbee, and stable, which more suitable for network; it hoped that this study can provide reliable value reference help future studies. Through installation different types sensors, nodes are automatically collecte...

This research paper presents Neuro-Fuzzy applications to Moving Picture Expert Group (MPEG-4) video transmission in IEEE 802.15.4 ZigBee wireless. ZigBee can operate within 2.4 GHz frequency with a data rate of 250 kb/s, which may interfere with other wireless devices functioning within the same frequency band such as WiFi and Bluetooth. MPEG-4 Variable Bit Rate (VBR) video demands large bandwi...

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...

The low cost, low power, low complexity Zigbee defined in IEEE standard 802.15.4 for low rate wpan’s upon MAC and physical layer. The objective is to make possible of incalculable process among next generation devices with small transmitters and agree to communicate between devices with central PAN co-ordinator. Thus zigbee desires efficient routing ptotocol to deal with lowest amount of energy...

The basic functions and the relative concepts of ZigBee network are analyzed in this paper. The implementation method of ZigBee network layer is proposed, it includes how to build a new network, add a node to the network, send data and receive data. The distributing address assigning mechanism, the tree hierarchical route algorism and AODVjr algorism are implemented. Finally, the ZigBee network...
