elements of sensor networks. WSN has many types of sensors, and it can detect a vari- ety of parameters, including temperature, humidity, noise, light intensity, and size, speed and direction of moving objects. Therefore, WSN has a wide range of applica- tions. In many cases of monitoring, because of the constraints of conditions, environ- ment and time, it is difficult for the monitoring personnel to enter the monitoring site and monitor directly and efficiently. They need to monitor with the help of electronic equipment that can adapt to various complex environments. In this context, the remote monitoring technology based on WSN has been widely concerned and highly valued by the academic and engineering circles. The emergence of remote monitoring system makes people quickly and effectively know the detailed information needs to be moni- tored under the objective conditions that people can't reach the scene, and make deci- sions quickly through the relevant information obtained, thus saving a lot of time, hu- man and material resources, and greatly improving the efficiency.

Design and Implementation of the ZigBee Wireless Sensor Network Based on ARM

Design and Implementation of the ZigBee Wireless Sensor Network Based on ARM

The antennas play a key role in the process of receiving and transmitting infor- mation in wireless sensor networks, whose performance will directly affect the com- munication distance, node power consumption, network stability and other indicators. The 2.4 GHz monopole whip antenna has been put on the market already. Generally speaking, its cost is higher (compared with PCB antenna) and its resonance frequency sometimes varies greatly due to the influence of package characteristics. While the manufacturing process of PCB plates allows the integration of antennas on the circuit boards; therefore, the antennas can be welded to the PCB boards. With regard to the latter option the production cost of the antennas can be lowered on one hand; it is also convenient to adjust the resonant frequency and impedance of the antennas with vector network analyzers on the other hand, because the parameters of the PCB plates affect the radiation performance of the antennas.

Design of intelligent sensor based on BP neural network and ZigBee wireless sensor network

Wireless sensor network node of the network Zigbee input feature factor node layer neuron number is the system (variable) number; the output layer neuron node number is the number of target. Hidden layer nodes selected by selecting experience, usually set as input layer node number 75%. If the input layer has 7 nodes, 1 node in the output layer, the hidden layer can temporarily set to 5 nodes, which form a 7-5-1 BP neural network model. In the training, practical but also on the hidden layer nodes of different number 4, 5, 6 respectively, finally determine the network structure of the most reasonable. To determine the initial weights, the initial weights are not completely equal to a set of values. Have demonstrated, even determine the existence of a group of non equal the system error smaller weights, if the initial set of Wji values are equal to each other, they will always remain equal in the learning process. Therefore, in the process, we design a random number generator program, a random number generating a set of a 0.5~+0.5, as the initial weights of the network.

Design and Implementation of Agricultural Information Acquisition System Based on ZigBee and Qt

But traditional image transmission systems are expensive to deploy, and it needs to be energized all the time, it allows the associated devices to operate at high speed and operate in a high power mode, the whole system has great load and high power consumption. Therefore, it is very important to design a low power, security system which is ad hoc network, easy to deploy, and it can transmit images. Taking into account the fixed growing environment of agricul- tural products, image sampling is only required in a certain period. Therefore, the Wireless Sensor Network can be used to monitor the image of agricultural products and the temperature and humidity parameters. As we know, ZigBee is a wireless communication technology with the characteristics of low power consumption, low rate and ad hoc network, and has been developing rapidly in recent years. It can reduce the size of the Wireless Sensor Networks and reduc- ing power consumption [2]-[9]. According to the above reasons, it is particularly important to design a set of agricultural products information collection system. Therefore, we developed the system with characteristics of stable performance, perfect function and friendly interface based on ZigBee Wireless Sensor Network and Qt graphics library which is crossing platform [10] [11] [12].

Design and Simulation of Wireless Sensor Network Topologies Using the ZigBee Standard

Design and Simulation of Wireless Sensor Network Topologies Using the ZigBee Standard

ZigBee is one of today's most useful technologies in the wireless sensor network industry. ZigBee, which is a new standard for wireless communication [14], is based on the IEEE 802.15.4standard announced in 2003 by the IEEE [15, 16]. ZigBee is established on powerful radio (physical layer) and MAC (Medium Access Control) layers defined by the IEEE 802.15.4 standard. It utilizes a standard CSMA/CA media access mechanism and supports star, tree and mesh topologies. IEEE 802.15.4 defines three license-free frequency bands. The first band uses the 2.4 GHz frequency band, i.e., the ISM (Industrial Scientific and Medical) band, and has 16 channels. The second band uses the 902-928 MHz frequency band with 10 channels. The other uses the 868-870 MHz frequency band with only one channel. The capacities of these frequency bands are 250 kb/s, 40 kb/s and 20 kb/s, respectively [15,17,18]. ZigBee deals with transferring certain amounts of data between devices used in personal area networks, measurements with networks, detection, monitoring and checking the applications. However, it is not suitable for large-size file transfers like Wi-Fi or Bluetooth. ZigBee is differentiated from Wi-Fi or Bluetooth in terms of communication approach between multiple devices, and works over simple networks with less power consumption and cost, also providing communication with lower bandwidth demands. In Table 1, a comparison of the features of ZigBee and some other wireless technologies is shown [15, 19]. As understood from the table, although the battery life of Bluetooth is 1-7 days, ZigBee’s battery life is 100-1000 days. In addition, while Wi-Fi’s fields of success are usually speed and flexibility, it can be said that ZigBee’s success rests in durability, cost and power consumption.

Comparative Evaluation of Three Wireless Sensor Network Transceivers in a High Radiation Environment

Comparative Evaluation of Three Wireless Sensor Network Transceivers in a High Radiation Environment

To examine the suitability of using industrial wireless sensor network devices in a high level radiation environment, three most commonly used wireless sensor network devices, ZigBee, WirelessHART, and ISA100.11a, have been tested in a radiation environment during on-power operations. A 60Co gamma radiation source is used to provide a consistent radiation environment. The operating conditions of key components on the devices are monitored continuously so that the first failed component can be identified in the post-analysis. It is interesting to observe that the wireless device based on ZigBee protocol has the strongest radiation tolerance, while WirelessHART and ISA100.11a devices share similar outcomes. A very important conclusion is that these devices can only survive for a limited amount of time, so much shorter than needed for use in a monitoring system for severe accident. Hence, adequate protections against total radiation exposure have to be taken either through shielding or redundant design. This study provides a useful reference for the design of wireless devices and networks to be deployed in high level radiation environments.

Zigbee Sensor Network Integrated with 4G Using Tree Routing for IoT Applications

Zigbee Sensor Network Integrated with 4G Using Tree Routing for IoT Applications

ABSTRACT: Internet of Things (IoT) is identifiable objects uniquely and their representations of an IoT are like structures. The concept of IoT is to develop the information in sense. And the device interacts without the need of human. Zigbee is a communication protocol and it is used to transmit data over long distances by passing data through the intermediate devices to cover longer distant. ZigBee is the emerging standard for ad hoc networks based on IEEE 802.15.4. It provides secure networking and can be used anywhere at any time. It can be easily implemented with any type of wireless generation and It requires less power to operate. 4G (Fourth Generation) is the next generation of wireless networks and it can secure data transfer. Speed of 4G provides fast and it can be achieved by OFDM modulation. World Wide Interoperability for Microwave Access (WiMAX) is wireless technology and it provides wireless data over longer distance. It provides a media access control (MAC) and the proposes is full range of security features to secured the data exchange. It nearly transmits the data at 70 Mbps. In this paper, Zigbee Wireless sensor nodes real time data transmission integrated with 4G Technology using tree routing for long distance Secure Communication with high mobility and it is proposed and analysed by using OPNET. Tree routing is used to find the next hop knob for a given destination address without routing tables. Still, a sender cannot know that the destination is situated close by or if it is not in the sub-tree. Even though the tree routing is capable in the observation point of memory usage. The concert such as Jitter, data sent, delay and packet delay variation and end-to-end delay are simulated.

Design of Micro strip Symmetrical Dual band Filter Based on Wireless Sensor Network Nodes

Design of Micro strip Symmetrical Dual band Filter Based on Wireless Sensor Network Nodes

Traditional Butterworth, Chebyshev, and elliptic func- tion filters can increase the design order of the filter to improve the filter’s out-of-band suppression and fre- quency selectivity, but the designed filter is usually single-band, not only the size is large, but also the filter’s in-band characteristics are not ideal [36]. Generalized Chebyshev filter (GCF) is also known as quasi-elliptic function filter. It is between Chebyshev and elliptic func- tion filter, which has excellent in-band characteristics and steep edge characteristics [37, 38]. The transmission zeros of generalized Chebyshev filter can be flexibly con- trolled, which can be used to improve filter selectivity and stop-band isolation. In order to improve the in-band and out-of-band performance of the filter, the communi- cation band of the filter is extended from a single band to a dual band. Based on the synthesis theory of general- ized Chebyshev filter, the frequency transformation is carried out with low-frequency prototype, and the design from low-frequency prototype to dual-band filter is real- ized with a cross-coupling synthesis theory.

A Study of Advanced Wireless Networks Technology Implementation

A Study of Advanced Wireless Networks Technology Implementation

Fig. 2 depicts the architecture of a terminal that is capable of operating in a CRE context. The terminals include software and hardware components (layer 1 and 2 functionalities) for operating with different systems. The higher protocol layers, in accordance with their peer entities in the network, support continuous access to IP-based applications. Different protocol boosters can further enhance the efficiency of the protocol stack. Most communications networks are subject to time and regional variations in traffic demands, which lead to variations in the degree to which the spectrum is utilized. Therefore, a service’s radio spectrum can be underused at certain times or geographical areas, while another service may experience a shortage at the same time/place. Given the high economic value placed on the radio spectrum and the importance of spectrum efficiency, it is clear that wastage of radio spectrum must be avoided. These issues provide the motivation for a scheme called dynamic spectrum allocation (DSA), which aims to manage the spectrum utilized by a converged radio system and share it between participating radio networks over space and time to increase overall spectrum efficiency as shown in Fig. 3.
