Abstract

Video transmission effectiveness in the Ad Hoc network is becoming important recently, if different routing protocols are applied. Some researchers conclude that the reactive protocols are better for file transfer protocol (FTP) and constant bit rate (CBR) or hypertext transfer protocol (HTTP) transmission in an Ad Hoc wireless network but the performance report of video transmission is not much. This study adopts Qualnet (Network Simulator) as a simulation tool for environmental designing and performance testing, and employs an experimental design with eight groups. Our experiment shows that: (1) The performance of AODV (reactive) protocol is better than DSDV, ZRP and DSR when the transmission load has only one video stream; (2) Proactive (DSDV) and Hybrid protocols (ZRP) are better for a smaller Ad Hoc network when it transmits a video stream with some applications (VoIP, FTP and CBR). We conclude that packet loss rate is sensitive to the quality of video transmission and it has negative relationship with Peak Signal‐to‐Noise Ratio (PSNR) value. In addition, our experiment also shows that PSNR is a simple Metric for the performance evaluation of video transmission.

Abstract

Web traffic is doubling every year, according to recent global studies. The user needs more information from Web sites and wants to spend as little time for downloading as possible. Simultaneously, more Internet bandwidth is needed and all ISPs are trying to build high bandwidth networks. This paper presents a case study that calculates the reduction of the time needed for a Web page to be fully downloaded and delivered to the user. Presents a way to calculate the reduction of data transfer, bandwidth resources and response time when the HTTP/1.1’s compressing feature is enabled (either in plain hypertext files or the text output of CGI programs or dynamically generated pages). Measurements are taken from five popular Web sites in order to validate our statement for reduction in transfer time. The definition of the mean size of a Web page that commercial Web sites have is additionally in the scope of this paper.

Abstract

The feasibility of publishing an electronic journal which will be accepted by the scientific community has always been hampered by factors such as a lack of standardisation of data transmission codes, limitations regarding the incorporation of graphics and photographs, as well as the absence of special columns, book reviews, letters to the editor, product reviews and advertisements. Standardised communication protocols such as TCP/IP have brought this dream one step closer to reality. The final step could be an electronic journal published through the World Wide Web (WWW), currently one of the frequently used Internet navigators. Three WWW specifications provide the ideal arena for electronic journal publishing: URL (uniform resource locator), HTTP (hypertext transfer protocol), and HTML (hypertext markup language). These specifications provide a standardised structure for storing, accessing and sending data, including multimedia (even sound and video) files. The possibilities of such a structure for electronic journal publishing are remarkable: full‐text retrieval could not only be by keyword but also by following hypertext links across articles — even to nodes in other computer systems. In this article the possibilities of publishing via the Web will be addressed and some hints for setting up and maintaining a multimedia scholarly journal will be provided.

Abstract

This paper outlines the evolution of World Wide Web protocols. The paper reviews the original protocols developed for the web, in addressing, transport and data formats. A review of developments of the protocols is given, including developments of web data formats (HTML 4.0, cascading stylesheets and XML), transport (HTTP/1.1 and HTTP/NG) and addressing (URLs). The paper describes how the web initially lacked a metadata architecture and outlines the emergence of a metadata architecture for the web. The paper includes a review of web technologies which have a social impact on our society, including the Web Accessibility Initiative, the Digital Signature Initiative and the Platform for Privacy Preferences Project.

Abstract

We have recently completed a survey of the use of hypertext systems in academic, public and special libraries within the United Kingdom. A questionnaire and both telephone and face‐to‐face interviews revealed that the largest application of such systems in academic libraries is the use of the World‐Wide Web for networked document retrieval. This paper discusses the current usage of the World‐Wide Web by academic library services, illustrating the range of facilities that libraries are starting to make available to their users.

Abstract

Materials for teaching, learning and research are moving into the digital sphere. This move is affecting scholarly communication, teaching and learning in the academic community in important ways. These are significant changes, operating at technical, service, organisational and cultural levels. In this paper we wish to examine some of these changes. However, our aims are modest: we will focus on technical developments and on some of the emerging services that these are making possible.

Abstract

Purpose

This study aims to provide a system capable of static searching on a large number of unstructured texts directly on the Web domain while keeping costs to a minimum. The proposed framework is applied to the unstructured texts of Migne’s Patrologia Graeca (PG) collection, setting PG as an implementation example of the method.

Design/methodology/approach

The unstructured texts of PG have automatically transformed to a read-only not only Structured Query Language (NoSQL) database with a structure identical to that of a representational state transfer access point interface. The transformation makes it possible to execute queries and retrieve ranked results based on a specialized application of the extended Boolean model.

Findings

Using a specifically built Web-browser-based search tool, the user can quickly locate ranked relevant fragments of texts with the ability to navigate back and forth. The user can search using the initial part of words and by ignoring the diacritics of the Greek language. The performance of the search system is comparatively examined when different versions of hypertext transfer protocol (Http) are used for various network latencies and different modes of network connections. Queries using Http-2 have by far the best performance, compared to any of Http-1.1 modes.

Originality/value

The system is not limited to the case study of PG and has a generic application in the field of humanities. The expandability of the system in terms of semantic enrichment is feasible by taking into account synonyms and topics if they are available. The system’s main advantage is that it is totally static which implies important features such as simplicity, efficiency, fast response, portability, security and scalability.

Abstract

This contribution looks at some relatively new and recent advanced tools, techniques, methods and standards related to the Internet which form the basis for mixtures of documents and services, which we can call ‘document+program hybrids’. The new Internet systems contribute to an evolution from documents on the one side and computer programs on the other side, neatly separated, apart from each other, without much interaction, so that the static document can also exist without computers and networks, to hybrid systems where the classical distinction between the contents and the container is blurred; where all components are integrated, interwoven and exist in synergy with each other; they can be more dynamic and interactive, in comparison with more classical and static documents, by involving and exploiting the power of computers and networks. A collection is presented of Internet‐based sources (URLs) that can serve as illustrations. Recent methods, techniques, standards and protocols on the Internet that form the basis of the evolution are listed. As professional information intermediaries, the authors also consider the impact in the area of online access to information and knowledge.

Abstract

The World Wide Web has become an important resource of timely information for the information professional. Unlike previous (traditional) formats of information, especially paper‐based publications, the Web has also brought the concept of electronic publishing within reach of any person who has browser access to this Internet navigator. It therefore implies that the information professional can also take part in the publishing process by creating and maintaining a homepage on the Web. Although a few articles have been published on homepage maintenance by information services, not much has been made available about the requirements for homepage design, or guidelines for the planning and structuring of a complete homepage environment. This article provides a few basic guidelines on homepage design, arguing that the physical appearance of a homepage is similar to that of a good graphical user interface (GUI). In designing a complete homepage file, the premise is that basic hypertext design principles could also be applied in the World Wide Web environment.
