This paper investigates the problem of energy consumption in wireless sensor networks. Wireless sensor nodes deployed in harsh environment where the conditions change drastically suffer from sudden changes in link quality and node status. The end-to-end delay of each sensor node varies due to the variation of link quality and node status. On the other hand, the sensor nodes are supplied with limited...
This paper investigates the MAC protocol tailored for wireless sensor networks deployed in the intertidal environment (IT-WSNs) where the ebb and flow of the tide influence the packet transmission. Most packets fail to be delivered when the sensor node is submerged by seawater during high tide. To deal with it, an environment-aware electrode module is designed to detect the tide level and determine...
Due to the problems of Fourier algorithm and wavelet algorithm on harmonic detection, proposed harmonic detection algorithm based on a recursive filter in this paper. Unlike a wavelet, the central frequency and frequency window radius of the recursive filter can be adjusted separately, the magnitude frequency property (MFP) of its real part and imaginary part is identical, symmetrical and no side...
The permanent magnetic (PM) synchronous machine testing calls for high performance of the load motor drive control and signal conditioning. The traditional load drive control using motor-alternators cannot meet up with the requirements of the PM machine testing satisfactorily. The paper demonstrates a four-quadrant drive control of the dc load motor using a rectifier apparatus for the PM machine testing...
