Gantry crane is primary handling device in portal work, and also may cause serious accidences, so it is particularly important to monitor and assess the crane's structural health. By taking the gantry crane as a research object, ZigBee wireless network and the components of the structural health monitoring system based on ZigBee technology are introduced in this paper, and the testing point position...
In this paper, we propose RFID Laundry Management System (LMS), in order to provide low power consumption, high services, low operation costs and better monitoring. The proposed system consists of RFID tag, wireless RFID hanger and MFC software. To compare with other existing RFID system, our system was developed as a web application. Therefore, customer can check their cloth status through web page...
Miner enterprises are often equipped with generalpurpose machine tools, which are not in stream-line and hard to control by network. The paper puts forward an information management system to manage the work site automatically. With networking technology, which integrating the agreement of TCP/IP and 485, the information of the tools can be gathered automatically and the tools can be controlled effectively;...
In this paper we present an ambient intelligence system for modelling and control of power use within an office environment. We define a multi-scale model of the office worker, consisting of a coarse grained office user profile, together with a fine grained characteristics model to summarise their behaviours. Sensor data gathered from individual offices are used to create these models. Collected data...
In order to access to the time-Delay Performance of the Wireless Sensor Network, respectively preformed the time-delay experiment, simulation and theoretical analysis from the following aspects: the hops and hop spacing, MAC dormancy mechanism, back-off time and transmitted power, etc. Obtained the relations between the time-delay and the above factors. Systematically summed up the time-delay rules...
Being an important factor in designing Wireless Sensor Networks, network lifetime depends on the energy of the sensor nodes which is limited by the battery of the node. Clustering is considered to be an energy management strategy in wireless sensor networks, and Leach is one of the most well-known clustering mechanisms. Random cluster selection in this method has lead to its inefficiency. In this...
The paper presents modern PLC's network to Physiological parameter monitoring technology. In this paper a founding method and implement of the system for personal and real-time monitoring is described, including the operation of the whole system. The tests demonstrate that the system is stable, reliable as well as high timely and accuracy. This paper accords with the trend that the network is becoming...
Next generation telematic services are expected to play a key role in future automotive applications. In order to achieve strong integration between the services and the underlying network infrastructure there is a need for both simulation and emulation of the entire system. This paper presents a combined simulation and emulation approach for telematic services prototyping in an emulated wireless...
We are in an age where people are paying increasing attention to energy conservation around the world. The heating and air-conditioning systems of buildings introduce one of the largest chunk of energy expenses. In this paper, we make a key observation that after a meeting or a class ends in a room, the indoor temperature will not immediately increase to the outdoor temperature. We call this phenomenon...
In this paper the middle-way of the intelligent energy-saving system was constructed with embedded system PXA300 and the human-machine interface software was programmed with Visual Studio 2005 which was embedded into the system with the Operating System Windows CE. Users could get all the electricity power consumption and environmental parameters information detected by the wireless sensors scattered...
Data acquisition plays an important role in the field of modern industry control. In many cases, remote data should be transferred to monitor center which is far away from the manufacturing field. Traditional data acquisition system by means of wires could not satisfy the requirements. With the rapid development of embedded system, wireless communication technology and 3G technology, the remote data...
In this paper, first we discuss some basic knowledge about the random network coding, then we introduce the random linear network coding with some simple models. Secondly, we will consider the coding over packets that randomly arrive to a source node for transmission to a single destination. Then, for broadcasting retransmission, any node of multi-nodes requests the retransmission of information packets...
Certified e-mail protocol is a fair exchange of a message for a receipt between two potentially mistrusting parties over the network. A number of certified e-mail protocols have been studied in recent years. However, most of those protocols employ certificate-based cryptography and full trusted third party, which may not be suitable for wireless networks with limited resources such as power, computation...
Smart grid is a multidisciplinary area that integrates various aspects of power monitoring and control with wireless communication. One of these aspects is data analysis and decision making based on load management strategies. In this paper, a load management scheme is implemented by selective switching of loads in every consumer premises without shedding the entire load on the feeder. A lab prototype...
This paper describes a development of a routing algorithm (FARES -- Alternated Flow in WSN) for Wireless Sensor Networks (WSN). The proposed algorithm avoids spreading replicated messages in the network, saving energy. Moreover, it deviates the message flow from dead or overwhelmed nodes, providing fault tolerance. At the end, the paper shows experimental results obtained by a network simulator.
Current simulations supporting the Net-Centric Test battlespace do not accurately represent the impact of cyber threats and information operations. When cyber threats are considered, they are typically limited to a small number of isolated physical devices. To further limit consideration, insufficient attention is paid to cyber attacks launched on the basis of passive threats like the eavesdroppers...
Cosmic rays monitoring became a very studied field nowadays. A smart system for monitoring rays is composed of mobile devices that are able to measure in realtime the fastest particles which are moving in space. In this paper, a reliable, reduced cost and long-life system for monitoring rays is proposed. By integrating Geiger-Muller tube with very low power wireless devices, the system may be used...
This paper presents an investigation into a new peer-to-peer wireless network architecture for real time tele-haptic operation in distributed virtual environments (DVEs).

In the end, this paper designs an indoor location system of equipment based on RFID technology.
The field of research on activity recognition is relatively young compared to others, like computer vision. In more mature fields, algorithms are usually tested on standardized, reference datasets. This way, algorithms coming from different groups can be tested in a fair manner, which accelerates the process of developing new knowledge. Collecting a reference dataset under realistic settings for activity...
