Abstract: In this paper, it completes the analysis of GPS system requirements, system design based on Android, and Android smart phones equipped with GPS module can achieve positioning itself and basic path analysis. With further research, the Android phone will be able to achieve more services and applications using GPS technology.

Abstract: The information of various exhibitions is the base of a virtual reality system throughout the exhibition industry. In this paper, based on the basic needs of digitized acquisition of various types of exhibits in exhibition industry and using high-precision, non-destructive and non-contact three-dimensional scanning technology, a digitized acquisition and processing solution against the exhibits was proposed, which makes the sample of the exhibits meet certain precision. On this basis, the design and implementation of the organization and integration technology of various types of exhibition information was expounded. The system was applied to a number of digital museums and achieved expectable effect.

Abstract: This article argues that in terms of security flaws Linux operating system. On this basis, it focuses on improving Linux security in two ways, one is the use and management of Linux from a security point of view, the second is upgrading the system, and improves their security thoroughly.

Abstract: This paper has analyzed safety problem and vulnerability of wireless network. And it has made deeply research about variety and drawback of wireless network security model. It has put forward a novel general security model.

Abstract: This paper designed and developed a series of Windows operating system for basic platform CDN technology, combined with the Socket of TCP/IP technology and to the network distributed database for the center. From design to achieve several aspects of instant messaging system of communication server are expounded.

Abstract: Aiming at problems of test, layout and application about campus network and combining with fundamental characteristic, introducing primary technology about transition from IPv4 campus network to IPv6 one, This paper discusses the status of IPv6 support technology and presents basic concept that campus network can be formed Gradually through layout testing network and experimental network; At the same time, in order to offer practical technical reference to favorable upgrading and applying campus network of ordinary universities It also discusses some services and applications about IPv6 campus network.

Abstract: The presence of P2P technology makes the large-scale personal infringement possible. It has a great effect on the traditional publishing industry. This paper makes a theoretical analysis of copyright infringement of P2P service providers and researches into the mechanism of copyright protection. The results show that we should construct the copyright infringement confirmative rules and balance the relationship between the development of P2P technology and copyright protection.

Abstract: This paper is aiming at establishing a commonality fitness service system, which can support national fitness service, rapidly make reflection and satisfy mass information storage and treatment. It can offer common service platform combined resource with space for the public.

Abstract: Wireless Sensor Networks (WSNs) are used in many applications in military, ecological, and health-related areas. These applications often include the monitoring of sensitive information such as enemy movement on the battlefield or the location of personnel in a building. Security is therefore important in WSNs. However, WSNs suffer from many constraints, including low computation capability, small memory, limited energy resources, susceptibility to physical capture, and the use of insecure wireless communication channels. These constraints make security in WSNs a challenge. In this article we present a study of wireless sensor network and security issues. And we outline the constraints, security requirements, and attacks with their corresponding countermeasures in WSNs.

Abstract: The localization accuracy of traditional APIT localization algorithm for wireless sensor network depends on the Approximate Perfect Point-In-Triangulation Test (APIT), and the localization error can be promoted in sparse network. We design one improved localization algorithm (RTD-APIT) based on APIT by using the RSSI and the triangles deformation. RTD-APIT uses the RSSI to improve the APIT for achieving the preliminary location of unknown node, and expand or deform the triangles for solving the Point-In-Triangulation (PIT) problem well and enhancing the localization. Simulation shows RTD-APIT can reduce the localization error effectively, and it also promote the localization coverage.
