Abstract: The Internet of things is the technology extension and expansion of computer, Internet and mobile communication network. We will strongly rely on the Internet of Things in the future. The Internet of Things provides more conveniences, but it also will face more threats. In this article, we describe architecture of the Internet of Things, the function of every layer and what components every layer need. Our emphasis is to analyze the threats for the security and privacy at different levels of architecture in the Internet of Things.

Abstract: The web-based application system, which has so many advantages, such as wide range,no limit of area and time, fast and high efficiency, is more and more popular with the enterprises and job seekers. It provides the job seekers and the recruiters with an interactive platform, who has the function of remote service. Designing and developing the web-based application system by adopting the pattern of MVC, it not only can make the structure of the whole system clearer to partition modules easily and enhance the high cohesion and low coupling among all the layers and modules, but also can make it easier to add new business and function to adapt to all kinds of demand change. This paper will introduce the design philosophy and develop process of the web-based application system based on the pattern of MVC.

Abstract: With the rapid development of networking progress in colleges and universities, examination system based on Internet has already become one of the hotspots of researching and developing electronization in colleges and universities. Thus, according to the current needs of the traditional examination process,it is important to design and development of a multi-course and questions and more intelligent enhanced online examination system for different courses’ teachers to facilitate the needs of the organization according to the teaching exam. The paper introduced the major phases of designing and developing online examination system, designed and developed intelligent and enhanced online examination system with multiple curriculums and patterns, described process design in subsystems of background resources and subsystems of foreground application, and realized this interactive system ultimately.

Abstract: The development of computer simulation technology makes virtual reality technology gradually applied to various fields. The implementation of virtual campus roaming system is an important embodiment. This paper combines with 3 d graphics rendering engine Open Scene Graph to study virtual campus interactive roaming system with a variety of functions. First of all, this paper introduces basic technologies interactive functions needed such as matrix transformation, quaternion in OSG, expounds OSG scene roaming theory, key research and implements human-computer interaction function of collision detection, scene roaming and path roaming, which introduces the switch between scene roaming, viewpoint following, path roaming by button C, and make campus roaming system have good immersion and realities and real-time performance.

Abstract: The popularity of Internet application makes web page illegal information filtering an important work. Based on mutual information model study of illegal information filtering in web page, this article first elaborated the theoretical basis of mutual information filtering algorithm, then designed a mutual information filtering algorithm based on improved formula, and designed and implemented illegal web page filtering system by using the algorithm and related technology and did a series of experiments, which effectively reduced the impact of negative factors on healthy development of network culture industry, and it is advantageous to the purification of social morality and social stability.

Abstract: This paper studies the impact of network time-lag on the spread of worms and virus, uses Lotka-Volterra equation theory with time delay, and studies the influence of network characteristics such as response time, predator copy size and interaction of network worms and predators.

Abstract: Based on the analysis of student apartment management system requirements, through the whole process of introduction of demand analysis, database design, overall design, detailed design, from the basic concept of ASP technology and SQL Server, under DreamWeaver development environment, this paper designed modules such as system architecture, development platform and database design strategy, built a student apartment management system based on ASP, which fundamentally changed the existing operation mode and service mode, realized the intelligent management of students apartment, and promoted the standardization and high efficiency of management.

Abstract: The paper, aiming at status of car networking, researched the key technology of dynamic traffic information services under the condition of car networking, proposed overall system structure based on the framework of car networking. Through traffic perception technology and dynamic induction technology and on the basis of analyzing the entire working process of car networking, the paper also realized the effective management and control on car networking. Experimental results show that this control technology model can better deal with data processing under the car networking.

Abstract: In order to solve the problem of coexistence between heterogeneous wireless system public frequency and spectrum hole problem based on the traditional wireless sensor networks, further play the modern wireless chip can support multiple different frequency channel advantage, is proposed for heterogeneous wireless sensor network characteristics of new technology to verify the privacy protection range query, and then on the basis, design and implementation of a heterogeneous wireless sensor network security range query prototype system, in order to increase the range of heterogeneous wireless sensor network query process verifiable privacy protection performance, so as to lay the foundation for the further application of science and technology in heterogeneous wireless sensor networks.

Abstract: School enterprise cooperation mode is the double oriented education model based on enterprises needs and teaching goal, and is an effective way of improving the universities teaching quality and cultivating students' practice innovation ability. Based on the network perspective and enterprise demand, the paper designs a kind of new business English teaching cases computer system, and the system uses the internet interactivity make enterprise staff and teachers can achieve real-time interaction. In order to optimize the teaching case system, this paper uses parabolic interpolation to carry on multi node modification for the network transmission signal, and then a single objective network nodes optimization model will be established, and the use of VB software carries out visual programming for the system, it can enhance the system easy to operate and real-time interaction, which provides a new method for the design of computer English teaching case.
