Geographic information assisted routing flexibility control in hierarchical Ad Hoc networks

Chinese Control Conference (2013)

Ming Tao Yuan Hua-qiang Wenhong Wei Zhixiong Li Yong Qin

In Ad Hoc networks with the hierarchical architecture, the triangle loop routing mode with serious network overhead is usually employed to process the communication for the nodes belonging to different Clusters, while the direct routing mode is not always the optimal one as well. By introducing the session arrival rate, the mobility and the position relationship of the communicating nodes, the analysis models of the network overheads caused by the triangle loop routing mode and the direct routing mode are deduced, and the numerical results of the network overheads with respect to the related parameters are analyzed as well. On this basis, a geographic information assisted routing flexibility control strategy (GI-RFC) is proposed, and the routing mode will be dynamically determined in terms of the positions of the communicating nodes to reduce the overall network overhead. The analysis results show that GI-RFC outperforms solely using the triangle loop routing mode or the direct routing mode in different network conditions.

A New Two-Step Fingerprint Classification Scheme Design

Journal of Dongguan University of Technology (2009)

Weimin Xiao Yuan Hua-qiang

We describe a new two-step fingerprint classification scheme in this paper.In the first step we adopt a MKL-based classifier to select the two-most-likely classes,which means that it divides the five-class problem to a two-class problem,followed by utilizing a specifically trained SPD classifier to do the final classification.The experimentation is performed on NIST DB4,which is one of the most important benchmarks in this area,showing that the new approach gets better results than the methods previously published in the literature,with the accurate rate being 95.5%and 96.9%for the five-class problem and four-class problem respectively.

UPLC-MS/MS fast determination of folic acid in infant formula

Zhongguo rupin gongye (2013)

Yuan Hua-qiang

Established a rapid test method to assay the content of folic acid in infant formula.The sample solution was adjusted pH value to 4.6 with 50% formic acid,then precipitated protein through high-speed centrifugation.The upper clear liquid filtered with 0.2 μm membrane and determined using UPLC-MS/MS system.The samples were separated on an Acquity UPLC HSS T3 column and quantified with multiple reactions monitoring(MRM) mode.The limit of detection(LOD) and limit of quantification(LOQ) of this method is 0.005 μg/mL and 0.02 μg/mL.The calibration curve was linear over the range of 0.1~1.0 mg/L and the coefficient(R2) was 0.9996.The recovery of the method is 93.4%~98.7% and the relative standard deviation of the method is 3.80%.The experiment indicated that this method is easy to operate,have good precision and accuracy and strong selectivity and the method is appropriate for the determination of folic acid in infant formula.

Dynamic Routing System for WSNs Based on Policy Engine

Zusheng Zhang Zhao Tie-Zhu Yuan Hua-qiang

Routing protocols in wireless sensor networks tend to be designed for a particular task type and network status. The dynamic routing system can adaptively choose the optimal performance of routing protocols at run time. Based on policy engine, a dynamic routing system is designed for wireless sensor networks. This work uses a modular design approach which makes each sensor node to carry multiple routing protocols. Resources, such as neighbor table and output buffer, are shared between routing protocols. A routing protocol switching mechanism is implemented based on the policy engine. Experimental results show that, in multitasking network environments, dynamic routing can meet the quality of service while effectively reducing energy consumption.

Fingerprint minutiae feature encryption based on fuzzy vault scheme

Jisuanji gongcheng yu sheji (2010)

Yuan Hua-qiang

The existing fingerprint fuzzy vault schemes are not secure when they are used to encrypt a short secret,a novel fingerprint feature encryption method is proposed based on fuzzy vault scheme.First,the degree of encoded polynomial of fuzzy vault scheme based on the decryption requirement is sepecified,and the secret based on the specified degree sequentially is hided.In this way,the proposed method avoided the drawback that the degree of encoded polynomial of fuzzy vault is determined by the length of secret,and solved the problem of insecurity in the existing method.
