Present attack problem to wireless local area network. Propose IDS model architecture with agents to monitor attack-related activity within a wireless local area network. And introduce the role of components in the model. Each agent operates cooperatively yet independently of the others, providing for efficiency, real-time response and distribution of resources. This architecture provides significant advantages in scalability, flexibility, extensibility, fault tolerance, and resistance to compromise.

With the increasing popularity of the wireless network, the security issue for mobile users could be even more serious than it can be expected. Here it is need to search for new architecture and mechanisms to protect the wireless networks and mobile computing application. This paper focuses on intrusion detection and security consideration in wireless local area networks (WLANs) and also presents intrusion detection for WLANs, which gives a wireless intrusion detection system and its architecture consideration. A wireless IDS is similar to a standard, wired IDS, but has additional deployment requirements as well as some unique features specific to WLAN intrusion and misuse detection. Meanwhile, we discuss some issues with wireless networks and Intrusion detection solution to wireless networks.

Wireless intrusion detection systems are an important addition to the security of wireless local area networks (WLANs). We focus on intrusion detection and security consideration in wireless local area networks. We present intrusion detection for WLANs, give wireless intrusion detection systems and system architecture considerations. We also present a conceptual model for an IDS agent. IDS agents can cooperatively participate in global intrusion detection actions. These individual IDS agents collectively form the IDS system to protect the mobile wireless network. Meanwhile, we introduce some infrastructures as elements of wireless IDS for WLANs.

This paper describes the design of a decision support module (DSM) for an intrusion detection system, which can provide active detection and automated response support during intrusions. The primary function of the decision support module is to provide recommended actions and alternatives and the implications of each recommended action. In the decision support module, the GA (genetic algorithm) was run over a subset of the data, called the training data, and then tested over the entire data set to test real-world performance. The model generated by this GA was based on a new method of data analysis for the intrusion detection problem. Each node in the model's decision tree was designed to hold a randomized coefficient for the data, so that this coefficient multiplied by the data would yield a weight for the certainty of whether a certain record was an attack or not. The coefficients were based on ephemeral random constants (ERC), random numbers generated by the GA specific to mathematical modeling.

The current debate about the teaching of data structures is hampered because, as a community, we usually debate specifics about data structure implementations and libraries, when the real level of disagreement remains implicit - the intent behind our teaching. This paper presents a phenomenographic study of the intent of CS educators for teaching data structures in CS2. Based on interviews with computer science educators and analysis of CS literature, we identified five categories of intent: developing transferable thinking, improving students' programming skills, knowing "what's under the hood", knowledge of software libraries, and component thinking. The CS community needs to first debate at the level of these categories before moving to more specific issues. This study also serves as an example of how phenomenographic analysis can be used to inform debate on syllabus design in general. Copyright 2004 ACM.

This paper describes a novel multi-rate multicast congestion control scheme based on the well-known proportional plus integrative control technique, where the control parameters can be designed to ensure the stability of the control loop In terms of source rate. The congestion controller is located at the next upstream nodes of multicast receivers and has explicit rate (ER) algorithm to regulate the rate of the receivers. We further analyze the theoretical aspects of the proposed algorithm, show how the control mechanism can be used to design a controller to support many-to-many multi-rate multicast transmission based on ER feedback, and verify its agreement with simulations in the case of bottleneck link appearing in a multicast tree. Simulation results show the efficiency of our scheme in terms of the system stability, high link utilizations, fast response, scalability, high throughput and fairness.

Adaptive stabilization for cascade nonlinear systems

引用

Chinese Journal of Systems engineering and Electronics 2004年第2期000卷

An adaptive controller of full state feedback for certain cascade nonlinear systems achieving input-to-state stability with respect to unknown bounded disturbance is designed using backstepping and control Lyapunov function (CLF)techniques. We show that unknown bounded disturbance can be estimated by update laws, which requires less information on unknown disturbance, as a part of stabilizing control. The design method achieves the desired property: global robust stability. Our contribution is illustrated with the example of a disturbed pendulum.

Currently, a large gap exists between the number of open software engineering positions and the number of qualified software engineers to fill those positions. The Industry/university (I/U) subgroup of the Working Group on software engineering Education and Training (WGSEET) is investigating active collaborations between companies and universities in which non-software professionals and practitioners without formal software education are reeducated to become software engineers. This paper describes the current status of work performed by the I/U subgroup in the investigation of reeducation collaborations. It is our goal to identify the common characteristics of successful collaborations in order to provide guidance to universities and companies when constructing a collaborative program, as well as to promote future collaborations. In this paper, we report on the current activity of the I/U subgroup, describe the features of successful collaborations identified so far in our research, and provide some conclusions as to the usefulness of such collaborations. © 2002, Taylor & Francis Group, LLC.

Cauchy - Schwarz bound on the generalized Marcum Q-function with applications

引用

Wireless Communications and Mobile Computing 2001年第2期1卷 243-253页

作者： Annamalai, A. Tellambura, C. The Bradley Department of Electrical and Computer Engineering Virginia Polytechnic Institute and State University 206 North Washington Street Suite 400 Alexandria VA 22314 U.S.A.

The Cauchy-Schwarz bounding technique is used to derive useful bounds on the generalized Marcum Q-function and its complement. Three new exponential-type bounds on QM (α, β) are derived, and these are found to be tight and useful for a number of applications of interest. One such example is the derivation of an upper bound on the average symbol error rate probability for noncoherent and differentially coherent communication systems over generalized fading channels. It is shown that these exponential-type bounds are considerably tighter than the Chernoff bound (Rappaport SS. IEEE Trans. on Information Theory 1971;17: 497-498) counterpart. Numerical results also reveal that the tightness of one of the exponential-type bounds is comparable to the bound obtained in Simon and Alouini (IEEE Trans. on Communications 2000: 359-366), while another is found to be superior than that obtained in Simon and Alouini over a wide range of arguments.

For many, the software engineering profession is still viewed as immature. The authors contend that a major problem has to do with the current educational model(s) for software. Most computer science graduates pursue careers in software development/software engineering. Only recently, a few B.S. in software engineering programs began their existence. Analyses of several of these programs reveal a lack of coherent design. Some are housed in an engineering school and have the 'flavor' of engineering but lack enough emphasis on software engineering core. Some are housed on traditional CS departments, have a strong CS component with a few SwE courses, and no engineering focus. What is the right "mix"? Which of the existing BSSwE programs can be accredited? What educational model will most likely help produce a professional software engineer? science? engineering? Technology? This paper addresses these and other related topics and controversial issues.
