Characterization of Internet Traffic in UUM Wireless Networks

The development in communication technology and the propagation of mobile devices, lightweight, with built-in, high-speed radio access in wireless are making wireless access to the Internet the popular situation rather than a wire line. Whereas, the growth of the wireless network with additional mobile devices in the UUM and increasing number of users led to slow wireless connection. Therefore, understanding the behavior of traffic analysis helps us to develop, manage WLAN technology, and deploy. It help us to apply our workload analysis results to issues in wireless network deployment, such as capacity planning, and potential network optimizations, such as algorithms for load balancing across multiple Access Points (APs) in a wireless network. The trace composes of two parts: firstly, one that connects to the core switch in computer center which is connected with the distribution switches that link the Access Point (APs) with the wireless network at campus, and secondly, another one for the measurement of bulk data transfers and interactive data exchange between two nodes in UUM library, which had been initiated at that time. This thesis investigates the performance network and users' behavior in UUM wireless network

Institutional aspects of standardization: jurisdictional conflicts and the choice of standardization organizations

"In den letzten beiden Jahrzehnten ist die Zahl der Standardisierungsorganisationen im Bereich der Informations- und Telekommunikationstechnik rasch gewachsen. Neben neuen offiziellen Organisationen auf der regionalen Ebene sind viele private Konsortien und Foren entstanden, die sich mit den bestehenden nationalen und internationalen Organisationen ergänzen oder auch mit ihnen konkurrieren. Die Landschaft der Standardisierungsorganisationen und die Beziehungen zwischen ihnen werden untersucht und zudem die institutionellen Faktoren aufgezeigt, die dazu beitragen, dass Kompetenzkonflikte relativ selten auftreten und nicht sehr intensiv sind. Die institutionellen Merkmale kanalisieren nicht nur das Verhalten der Standardisierungsorganisationen untereinander, sie beeinflussen auch Geschwindigkeit, Exklusivität, Kosten und Marktakzeptanz der Standardisierung und leiten damit die Entscheidung der Unternehmen, an welche Organisation sie sich mit einem Standardisierungsproblem wenden." [Autorenreferat]"Standardization organizations in the area of information and telecommunications technology have mushroomed in the last two decades. In addition to new official organizations at the regional level, many private consortiums and forums have been set up that complement and compete with the incumbent national and international organizations. The organizational landscape and the relations between the standardization organizations are examined, and institutional reasons that could explain why the frequency and intensity of jurisdictional conflicts has remained low are considered. Institutional features do not only frame a standardization organization's behavior toward other organizations, they also account for speed, exclusiveness, costs and market acceptance of standardization and thus influence firms' decisions as to which organization to turn to with a standards issue."

Office automation

Bibliography: p. 100-104.Office automation systems have become an essential tool for the operation of the modern office. With the emphasis of a modern office being placed on efficiency and ease of communication, office automation systems have become the backbone of successful businesses. COSNET is a prototype office automation system designed and implemented at the Department of the University of Cape Town and runs on Personal Computers that are linked to a NCR UNIX TOWER, which acts as the host. This dissertation investigates the different facilities supported by some of the office automation systems compared in this thesis, and describes the COSNET features. This prototype office automation system supports many of the facilities that are supported by large office automation systems. COSNET allows the user to define any MS-DOS based editor or word processor, and uses a simple editor for the creation of mail. The electronic filing facility allows documents to be created, filed, retrieved and deleted, and thus provides the users with the necessary features for document exchange. A user may set access permissions to each of his documents and may grant other users either read or write access to a specific document. The mail facility lets the user read, file, forward, delete and print a message, and supports classification of mail. A calendar facility is used as an electronic diary and stores all the user's schedules. These schedules may be viewed in either daily, weekly and monthly display modes. Read and write access to the calendar can be set by the user, in order to allow other users to manipulate his schedules. Any MS-DOS based application software can be added to COSNET. This facility allows the COSNET user to configure the office automation system to simulate the office environment. COSNET thus supports most of the necessary features required by an office automation system

The CSCW paradigm for software development

People work together to solve a wide variety of problems using different forms of cooperation for each class of problem. Modern technology is complex, and therefore it is unusual for an individual to attempt the development of a major project single-handedly. In an attempt to provide computer-based support for the problems that arise when two or more people attempt to cooperate to perform a task or solve a problem, the area of Computer Supported Cooperative Work (CSCW) becomes relevant. The software development process almost invariably involves cooperation that crosses group, professional, and subcultural boundaries. The complexity of software development demands that highly integrated groups of analysts, designers, and users are involved in the process. Many development activities may occur concurrently. The area of CSCW and advanced information technology, with its enormous capabilities for transmitting and storing information, holds considerable promise for the software development process.ComputingM.
