Video compression and communication has been an important field over the past decades and critical for many applications, e.g., video on demand, video-conferencing, and remote education. In many applications, providing low-delay and error-resilient video transmission and increasing the coding efficiency are two major challenges. Low-delay and…

As wireless cyber-physical systems (WCPS) are increasingly being deployed in mission-critical applications, it becomes imperative that we consider application QoS requirements in in-network processing (INP). In this dissertation, we explore the potentials of two INP methods, packet packing and network coding, on improving network performance while…

Efficient self-organizing virtual clusterheads that supervise data collection based on their wireless connectivity, risk, and overhead costs, are an important element of Wireless Sensor Networks (WSNs). This function is especially critical during deployment when system resources are allocated to a subsequent application. In the presented research,…

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…

As the Internet moves towards a three-layer architecture consisting of overlay networks on top of the IP network layer on top of WDM-based physical networks, incorporating the interaction between and among network layers is crucial for efficient and effective implementation of survivability. This dissertation has four major foci as follows:…

Pervasive computing is an emerging concept that thoroughly brings computing devices and the consequent technology into people's daily life and activities. Most of these computing devices are very small, sometimes even "invisible", and often embedded into the objects surrounding people. In addition, these devices usually are not isolated, but…

Describes an electronic mail system used by the Horseheads (New York) Central School Distict's eight schools and central office that saves time and enhances productivity. This software calls up information from the district's computer network and sends it to other users' special files--electronic "mailboxes" set aside for messages and…

When a special-education student in the Tucson (Arizona) Unified School District moves to a new address, that information is communicated quickly and efficiently to every office needing to know. School community members have discovered the value of a well-planned information-management system. Specifics about line speed, vendor reliability,…

Computing authorities at 34 research universities have launched an effort to create a national computer network for higher education several times as fast as the Internet. The network would be supported by several corporate partners in computer and telecommunications industries and by the federal government, would not replace Internet connections,…

When teachers, building-level administrators, and district officials can communicate freely with one another through computers, districts become more powerful. An integrated approach to computer technology will result in improved efficiencies. (MLF)

The University of California at Santa Cruz has completed a successful test of a wireless computer network that would enable students and professors to get on line from anywhere on campus. The network, linked by radio waves, could save millions of dollars in campus wiring costs and would better meet student and faculty information needs. (MSE)

Developers of Internet 2, an improved computerized information system designed for research purposes, are seeking federal support, suggesting that the new network's benefits would extend well beyond the academic realm. The educators behind the system propose that the system will create not only better electronics, but also new network applications…

Colleges and universities are anticipating significant benefits from electronic transfer of student transcripts and other data, including reduced costs and time savings, improved academic advising, and standardization of information format. Early testing of the recommended software suggests institutions find the system useful. (MSE)

As higher education institutions plan for the future, common agreement to build open distributed computing environments (DCE) using common standards such as those of the Open Software Foundation can help exploit new application design approaches that promote application sharing, a more efficient way of meeting upcoming challenges. (MSE)

Reasons for adopting Open Software Foundation (OSF) standards for distributed computing environments (DCE) within colleges and universities are examined. Adoption would promote interoperability across heterogeneous systems within and between institutions, aid in transition to client/server computing, and facilitate sharing and leveraging across…
