This paper is concerned with the iteration identification algorithm for Hammerstein model with complex-valued input for the fact that the existing algorithms are not valid for complex input. Based on the stochastic gradient algorithm, the extended stochastic gradient algorithm is proposed by defining new cost function for complex input. The extended hierarchical multi-innovation stochastic gradient algorithm is proposed by introducing multi-innovation identification theory and hierarchical principle to the extended stochastic gradient algorithm. Experimental simulations show that the extended hierarchical multi-innovation stochastic gradient algorithm has better performance than the extended stochastic gradient algorithm at the expense of computational complexity.

distributed denial of service attacks detection method based on conditional random fields

Journal of Networks 2013年第4期8卷 858-865页

作者： Chen, Shi-Wen Wu, Jiang-Xing Ye, Xiao-Long Guo, Tong National Digital Switching System Engineering and Technological R and D Center Zhengzhou China

In order to detect distributed denial of service (ddoS) attacks accurately and efficiently, a new detection model based on conditional random fields (CrF) was proposed. The CrF based model incorporates the signaturebased and anomaly-based detection methods to a hybrid system. The selected features include source IP entropy, destination IP entropy, source port entropy, destination port entropy, protocol number and etc. The CrF based model combines these IP flow entropies and other fingerprints into a normalize entropy as the feature vectors to depict the states of the monitoring traffic. The training method of the detection model uses the L-BFGS algorithm. And the model only needs to inspect the IP header fields of each packet, which makes it possible for real-time implementation even on real time network traffic. The CrF based model may have the ability to detect new form of forthcoming attacks, because it is independent from any specific ddoS flooding attack tools. The experiment results show that the CrF based method has higher detection accuracy and sensitivity as well as lower false positive alarms. Experiment with Kdd CUP1999, dArPA 2000 and generated attack datasets, the CrF based model outperforms other well-known detection methods such as Naïve Bayes, KNN, SVM and etc. The accuracy goes beyond 95.0% and the false alarm rate is less than 5.0%. Meanwhile, the CrF based model is robust under massive background network traffic. © 2013 ACAdEMY PUBLISHEr.

Today's Internet hosts a wide variety of network objects (namely, netOs) like contents, resources and functionalities and so on, which are often decomposed and distributed over the Internet to provide and support network-based services and applications conveniently. However, it is a big challenge to efficient management due to the huge number of existing netOs. Based on our investigations, most existing works that organizing those netOs in the computer network efficiently formulates network utility maximization problems (or network cost minimization). Although some works are effective in the corresponding aspects, the Internet still suffers from inefficiency and ossification. Instead of solving a concrete problem, we make the first attempt to model the numerical evolution of netOs (namely, EvoNetO) to uncover the hidden order of netOs. We prove that the problem of minimizing network cost is equivalent to fastest decay rate or slowest growth rate in the population dynamics. And then we find that the netOs distributed over the network will go to two extreme, i.e., r-strategists and K-strategists under the goal of minimizing network cost for netO placements. This phenomenon exists widely in the computer network.

This paper reports a stator shape optimization design for reducing the cogging torque of single-phase brushless dC motor adopting an asymmetric air-gap to make them self-starting. Time step 2d-finite element analysis (FEA) was carried out to analyze the characteristics of a single-phase brushless dC motor. To reduce the cogging torque and maintain the efficiency and torque, the Kriging model based on Latin hypercube sampling (LHS) and a genetic algorithm (GA) were used. As an optimal design result, the cogging torque on the optimal model was reduced. Finally, the analysis and optimal design results were confirmed by FEA and the experimental results. © 2014 IEEE.

A differential data reporting scheme for cooperative spectrum sensing

引用

International Journal of Applied Mathematics and Statistics 2013年第22期51卷 351-359页

作者： Wang, Jinghui Jin, Liang National Digital Switching System Engineering and Technological R and D Center Zhenzhou 450002 Henan China

Sharing local sensing data with the fusion center (FC) incurs reporting overhead, and is an important issue in cooperative spectrum sensing (CSS). In order to reduce the average number of reporting bits and thus the overhead, we propose a novel data reporting scheme in this paper. The proposed scheme, known as differential data reporting (ddr) scheme, decides whether a local decision is informative from the viewpoint of transmission and limits the reporting of redundant decision. The sensing performance and reporting overhead for both perfect and imperfect reporting channels are investigated. As shown by numerical results, ddr reduces the reporting overhead significantly, especially when the primary user (PU) traffic changes slowly compared to the sensing period. © 2013 by CESEr Publications.
