Distributed structural health monitoring (SHM) using wireless sensor nodes (WSN) requires frugal spending of the limited energy budget. We propose a reconfigurable heterogeneous architecture, combining a low-power micro-controller (MCU) with a Field-Programmable Gate Array (FPGA), as a means for energy-efficient in-sensor processing. Details covered include a generic communication interface between...
In this paper, a real-time detection system of runaway trains based on the wireless sensor network is proposed. The Giant magneto resistive (GMR) sensor is used to detect the train wheels. According to the difference of wheels types, locomotives and wagons can be distinguished. Wheel sensors are connected to the sensor node which could send detected signal to sink nodes by the radio. The sink node...
At present, water quality monitoring is the essential part to our country's aquaculture. In this paper, we developed a real-time water quality environment monitoring system based on wireless sensor network to acquire data of environmental factors of water quality. Also, the system can provide expert knowledge to deal with data for making control decision. Such a system is attractive because it ensures...

The design of WSN architecture need consider many aspects, such as deploy, energy...
Civil engineering construction site is a high-risk area, where many accidents occur, but most construction sites lack necessary safety monitoring and warning system. Compared to traditional monitoring system, the monitoring system based on wireless sensor networks has many advantages. According to the requirements of practical engineering, the safety monitoring system for civil engineering construction...
This paper presents a communications and software architecture in support of Prognosis and Health Monitoring (PHM) applications for renewable ocean-based power generation. The generator/turbine platform is instrumented with various sensors (e.g. vibration, temperature) that generate periodic measurements used to assess the current system health and to project its future performance. The power generator...
Nowadays security plays the major role in the network. Growing size of such proprietary networks creates increased opportunity for successful attack. Supervisory control and data-acquisition (SCADA) networks are more secure and vulnerable to attach from both internal and external intruders. It is the mechanism which is used to provide continuous monitoring and authentication to the network. Authentication...

Wireless mobile grids are one of the emerging grid types, which help to pool the resources of several willing and cooperative mobile devices to resolve computationally intensive tasks. These tasks are more sensitive to processor availability than are to memory or bandwidth. The mobile grids exhibit stronger challenges like mobility management of devices, providing transparent access to grid resources,...
The use of Graphics Processing Units (GPUs) in general purpose computing has been shown to incur significant performance benefits, for applications ranging from scientific computing to database sorting and search. In this paper we try to evaluate the execution of integer arithmetic operation on CPU and GPU processors. We evaluate the execution from both performance and power consumption perspectives.
