Management of large enterprise and Internet service provider networks is a complex, error-prone, and costly challenge. It is widely accepted that the key contributors to this complexity are the bundling of control and data forwarding in traditional routers and the use of fully distributed protocols for network control. To address these…

This dissertation presents a study of an Unmanned Ground Vehicle (UGV) navigation and coverage hole patching in coordinate-free and localization-free Wireless Sensor Networks (WSNs). Navigation and coverage maintenance are related problems since coverage hole patching requires effective navigation in the sensor network environment. A…

Video streaming has recently grown dramatically in popularity over the Internet, Cable TV, and wire-less networks. Because of the resource demanding nature of video streaming applications, maximizing resource utilization in any video streaming system is a key factor to increase the scalability and decrease the cost of the system. Resources to…

In this thesis, we consider estimation, coding, and sensor scheduling for energy efficient operation of wireless visual sensor networks (VSN), which consist of battery-powered wireless sensors with sensing (imaging), computation, and communication capabilities. The competing requirements for applications of these wireless sensor networks (WSN)…

Purpose: This paper presents an IT system -- Student Connectivity Module (SCM) -- designed to support administration of student exchange between universities in different countries, developed under the EU seventh Framework Program. The purpose of this paper is to share the acquired knowledge on existing difficulties in mobility management, propose…

The dynamic and high-stakes nature of education and training requires reliance on evidence-based practices and policies to make decisions about technology adoption and implementation. In the report, "Science of Learning and Readiness (SoLaR) Recommendation Report: Science of Learning Practices for Distributed Online Environments"…

This study is an assessment of Information Provision Services of Libraries in the 21st century in some selected academic libraries in Delta State. A descriptive survey was adopted in carrying out the research. The questionnaire was the instrument for data collection of which 62 were retrieved. Based on the findings of the study, it was recommended…

Scientific inscriptions--graphs, diagrams, and data--and argumentation are integral to learning and communicating science and are common elements in cyberlearning environments--those involving the use of networked learning technologies. However, previous research has indicated that learners struggle to use inscriptions and when they engage in…

This paper reports on the design and implementation of a cybersecurity camp offered as a cybersecurity learning experience to a group of female and male high school students. Students ranged in grade level from freshmen to senior. Student demographics, including any existing pre-requisite knowledge, were unknown to camp designers prior to the…

Most freshmen taking required, introductory information systems courses do not understand why they are required to take such courses and can't imagine that they will learn anything they don't already know. This paper presents an exercise that will excite and enthuse students about their computers and Information Systems in general. Every freshman…

Since information theory was developed by Claude E. Shannon, in addition to its primary role in communications and networking, it has broadened to find applications in many other areas of science and technology, such as microeconomics, statistics, and neuroscience. This thesis investigates the application of information theoretic viewpoints to two…

Link failures in wide area networks are common and cause significant data losses. Mesh-based protection schemes offer high capacity efficiency but they are slow, require complex signaling, and instable. Diversity coding is a proactive coding-based recovery technique which offers near-hitless (sub-ms) restoration with a competitive spare capacity…

The problem of attributing cyber attacks is one of increasing importance. Without a solid method of demonstrating the origin of a cyber attack, any attempts to deter would-be cyber attackers are wasted. Existing methods of attribution make unfounded assumptions about the environment in which they will operate: omniscience (the ability to gather,…

The purpose of this research effort was to develop a model that provides repeatable Location Management (LM) testing using a network simulation tool, QualNet version 5.1 (2011). The model will provide current and future protocol developers a framework to simulate stable protocol environments for development. This study used the Design Science…

The application of ubiquitous technologies in the improvement of education strategies is called Ubiquitous Learning. This article proposes the integration between two models dedicated to support ubiquitous learning environments, called Global and CoolEdu. CoolEdu is a generic collaboration model for decentralized environments. Global is an…
