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…

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,…

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…

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,…

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)

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…

Describes four successful cost-containment initiatives of the Midwestern Higher Education Commission, which was established to advance higher education in the Midwest through interstate cooperation. Projects include development of Academic Scheduling and Management Software; Internet-based activities; the Virtual Private Network, to reduce…

As more academic institutions spend larger sums of money to network their campuses and provide network connections to sources outside their campuses, questions emerge concerning the selection and configuration of appropriate network technologies and the appropriate types and levels of services to provide. Increasingly, academic administrators are…
