Resource-constrained is a critical issue in Wireless Sensor networks (WSN) applications. data aggregation (or data fusion) is one of the key techniques to solve the problem. data aggregation can effectively reduce the data traffic, thereby reduce energy consumption, and extend the network's survival time. The research of data aggregation relates to many aspects of technology, so that the design of efficient data aggregation algorithm is a challenging task. In this paper, we investigate the effect of essential operations, scheduling algorithm and aggregation tree construction, has on data aggregation performance. The main performance such as end-to-end delay and energy-consumption of different aggregation schemes has been studied and measured by simulation experiment. © 2011 IEEE.

In terms of the difficulty of vehicle tracking in complex environment of the visual surveillance system, an object tracking algorithm is proposed for the applications in practical visual surveillance systems for intelligent traffic. A block-based Gaussian mixture background modeling method for object detection is presented to reduce the computational complexity of moving vehicle object abstraction. An adaptive tracking algorithm fused with color features and texture features is described to better adapt the traffic scene variation. The experimental results show that the proposed algorithm can effectively deal with the complex urban traffic conditions and the tracking performance is better than the conventional particle filter method and single feature based non-adaptive object tracking method.

With the rapid development of information technology, the secrutiy problems of information systems are being paid more and more attention, so the Chinese government is carrying out information security classified protection policy in the whole country. Considering computer application systems are the key componets for information system, this paper analyzes the typical security problems in computer application systems and points out that the cause for the problems is lack of safe and valid isolation protection mechanism. In order to resolve the issues, some widely used isolation models are studied in this paper, and a New Application Security Isolation model called NASI is proposed, which is based on trusted computing technology and the least privilege principle. After that, this paper introduces the design ideas of NASI, gives out formal description and safety analysis for the model, and finally describes the implementation of the prototype system based on NASI. © 2011 ICST Institute for Computer science, Social Informatics and Telecommunications Engineering.

To improve the deduplication performance while keep a reasonable metadata cost and time cost at the same time, a state deduplication method based on variable-size sliding window and a universal model of performance-analyzing for the deduplication methods are proposed. According to this method, the data object is divided into non-overlapped mini chunks based on its content firstly, and then a variable-size sliding window, which uses the mini chunks as its basic unit of movement, is used to identify the duplicate data blocks. Further more, different chunking strategies are used on the data changing regions and the non-changing regions respectively. The theoretical analyzing indicates that this method can achieve satisfying deduplication performance even with a relatively larger expected chunk size, because it can reduce the metadata cost effectively and identify smaller duplicate data blocks. The experimental results on real data show that the average compression ratio of the method can be increased 13.02% than SWC, which has the optimal deduplication performance among the current deduplication methods. Moreover, the average time cost of this method is reduced 97.45% than SWC. This method is suitable for the applications of mass data backup in network environment, which have more rigorous requirements on the deduplication performance and the time cost.

Fractional differential is used to adjust the affinity matrix of the image and to extract more useful edge and texture information. A graph is constructed for the original image with edge and texture information calculated with fractional differential, and the Laplacian matrix is obtained and the eigenvector corresponding to the second eigenvalue is classified to get the final segmentation results. Experimental results show that the proposed method can extract more fine details, preserve more useful information and get more accurate results. © 2011 IEEE.

Proxy Mobile IPv6 (PMIPv6) is an emerging network-based localized mobility management scheme. Recently, Zhou, Zhang and Qin proposed an authentication method for PMIPv6. However, this paper shows that their scheme fails to achieve mutual authentication between the Mobile Node (MN) and network. It performs only unilateral authentication of the MN to network, and the MN has no information about the authenticity of the network, thus it is susceptible to network spoofing attack and malicious MAG attack. Then, an improved scheme is proposed to remedy these security flaws. © 2011 Springer-Verlag Berlin Heidelberg.

Security problems of an information system are mainly due to its internal vulnerabilities, by exploiting which external threats do harm to the system. Security Assessment of Vulnerabilities(SAV) is, with appropriate methods, to assess an information system by investigating vulnerabilities in its architecture, hardware, software, networks, and protocols. These methods can be divided into two categories: rule-based and model-based, and the later draws more research focuses at present. In this paper we make an extensive survey on existing model-based approaches to security assessment of vulnerabilities in information systems, analysing their working mechanics, advantages and disadvantages. Finally, conclusions are made on open problems in model-based security assessment, and on the possible future directions of the research.

A novel relief feature selection algorithm based on mean-variance model

引用

Journal of Information and Computational science 2011年第16期8卷 3921-3929页

The RELIEF algorithm is a popular approach for feature weight estimation. Many extensions of the RELIEF algorithm are developed. However, an essential defect in the original RELIEF algorithm has been ignored for years. Because of the randomicity and the uncertainty of the instances used for calculating the feature weight vector in the RELEIF algorithm, the results will fluctuate with the instances, which lead to poor evaluation accuracy. To solve this problem, a novel feature selection algorithm based on Mean-Variance model is proposed. It takes both the mean and the variance of the discrimination among instances into account as the criterion of feature weight estimation, which makes the result more stable and accurate. Based on real seismic signals of ground targets, experiment results indicate that the subsets of feature generated by proposed algorithm have better performance. © 2009 by Binary Information Press.
