An environmental monitoring system based on ZigBee wireless sensor network technology was researched in detail in this paper. Firstly, the technology working principle of ZigBee and its characteristics were introduced, and the characteristics of wireless sensor network and its application advantages were analyzed in comparison with the traditional network. Secondly, the overall scheme of the en...

With the development of industrial automation technology, the limitation of traditional cable control network has become increasingly prominent. Consequently, establishing a reliable data transmission network becomes a critical demand in industry. Increasingly, companies developing monitoring and control applications in industrial and commercial building environments are looking to wireless tec...

Gerade in den letzten Jahren kommen mehr und mehr Anwendungen auf Basis von drahtlosen Sensornetze auf dem Markt. So gibt es in den USA die Bestrebungen drahtlose Sensornetze für die Energieüberwachung (smart monitoring) einzusetzen, aber auch in der Hausautomatisierung, dem Gesundheitswesen, u.a. sind die Netze bestehend aus vielen kleinen Sensorknoten im Gespräch. Der de-facto Standard bzgl. ...

Ecological environment is the key point of improving the flower’s quality and quantity. Due to China's flower production management at a lower level, there is no scientific method in real-time monitoring of the flower’s ecological environment. In order to solve the problem such as high costs; poor monitoring point scalability, poor mobility and other issues in traditional flower basement’s data...

Element CXI's Elemental Computing Array (ECA) delivers faster reconfiguration time and higher computational density than Field Programmable Gate Arrays (FPGAs) with similar computational power. It provides higher computational power than Digital Signal Processors (DSPs) with similar power consumption and price. It also utilizes a library-based graphical development environment promoting ease of...

In this article, we present a multi-tool method for the development and the analysis of a new medium access method. IEEE 802.15.4 / ZigBee technology has been used as a basis for this new determinist MAC layer which enables a high level of QoS. This WPAN can be typically used for wireless sensor networks which require strong temporal constraints. To validate the proposed protocol, three complem...

Although formerly conceived for industrial sensing and control over Wireless Sensor Networks, LR-WPANs are registering an increasing interest in experimenting multimedia applications, with particular emphasis on evaluating the streaming capability of Zigbee networks. Due to their limited throughput they are not expected to provide high QoS, nevertheless there are several application scenarios s...
