Cloud computing is an Internet-based computing paradigm which may share resources to provide on- demand services to devices. Integrating smart grid into cloud computing is emerging and promising, and this integration may execute in the cloud based hierarchical multi-user data-shared environment, where security issues such as data confidentiality and manager authority may arise in the smart grid system...
ISO/IEC/IEEE 21451-5 standard provide a wireless communication model to facilitate access of smart sensors and actuators to a network. However, the 21451-5 standard integrates different wireless communication protocols in a sensor network system, and the overall complexity is higher than traditional sensor networks. Moreover, 21451-5 sensor networks that used in industrial control systems require...
Train positioning is a fundamental function which is required by many location-based railway applications. The rapid development of satellite navigation technology enables a better cost-effectiveness for the safety-critical railway train control systems. When using BDS (BeiDou Navigation Satellite System) in train control, it has to be ensured the positioning module takes full consideration of the...
We propose a framework for cooperative spectrum sensing in cognitive radio (CR) networks with adaptive energy threshold control for local spectrum sensing and an efficient approach for data fusion. Each secondary user (SU) carries out energy detection based local spectrum sensing, where the energy threshold is adaptively adjusted in real time according to both the SINR (signal to interference plus...
Vibration signal analysis is an effective and important method to research the state of diesel engine. But, utilizing signal feature to diagnose fault of diesel engine is a hard work. This paper took the fuel cut-off fault of WD615 as example, it selected the vibration signal of diesel engine in normal station and fuel cut-off fault station ,and calculated the vibration intensity values of signal...
In wireless sensor networks, object tracking is one of the important topics in research of wireless sensor networks. However, the core technology of object tracking is the positioning technique. In recent years, many positioning methods have been proposed. The main purpose of this paper is to achieve an object tracking mechanism with low complexity of computation and low cost based on various constraints...
In this paper, considering the imperfect (incomplete, imprecise, uncertain, inconsistent) information sources in information fusion, To avoid and reduce the influence of the mistaken or misleading information on the final precision of fusion, the ESMS (evidence supporting measure of similarity) filter is designed and added to generalized fusion machine (GFM), and an ESMS function (not unique) to select...
