Wide area computer networks offer users a large volume and variety of resources that can help them solve many kinds of daily problems in their work environment. However, the existence, let alone the contribution, of such resources is generally ignored by networkers. This represents a gap in the usability of items available in the network. This work discusses usability issues as perceived in the...

When a networked virtual reality system handles composite media audio and video as well as three dimensional computer graphics, the quality of the virtual space is also greatly affected by the currently available network and end system resources. In this paper, we discuss the architecture of a networked virtual reality system C3. We propose a new criterion called IoP(Importance of presence) for...

Computer and network security are central issues confronting organizations and individuals. This paper explores the use of biology as a reference discipline that can provide meaningful insight and innovation in the area of network security. Specifically, we propose a framework for thinking about network security by examining the similarities between the defense mechanisms of a cell, and the sec...

Fulp, Errin Wesley RESOURCE ALLOCATION AND PRICING FOR QOS MANAGEMENT IN COMPUTER NETWORKS. (Under the direction of Douglas S. Reeves) Computer networks must accommodate a wide variety of applications, ranging from simple file transfer programs to complex multimedia applications. Many of these applications require certain Quality of Service (QoS) guarantees for their proper operation. QoS guara...

Recent technological advances ease a volatile growth of digital contents. Cloud computing are novel computing expressions or symbol found on service and utilization of computing resources. Cloud computing engages groups of remote servers and interconnected software network that make available a centralized data storage online access to computer services or resources.

To provide Quality of Service (QoS) demanded by many online services (e.g., e-commerce), computer and network systems need to have QoS monitoring and adaptation which must be based on cause-effect dynamics relations among service activities, the state of system resources, and the QoS performance of service processes. This paper presents our study on cause-effect dynamics models for one of compu...

One of the most important assessment indicators of computer virus infections is epidemic tipping point. Although many researchers have focused on the effects of scale-free network power-law connectivity distributions on computer virus epidemic dynamics and tipping points, few have comprehensively considered resource limitations and costs. Our goals for this paper are to show that a opposed to t...
