JOHNNY S. K. WONG (wong@cs.iastate.edu)

Associate Professor of Computer Science


Major Interests: Broadband Integrated Services Digital Networks (BISDN), Distributed Computing Environment (DCE), Distributed Operating Systems, Performance Evaluation, Communication Protocols, Object-Oriented systems and Databases, Common Object Request Broker Architecture (CORBA), Hypermedia Systems, Multimedia Information Systems.


Current Research: Dr. Wong's research interests include design and implementation issues in operating systems, distributed systems and multimedia communications. Current activities in operating systems and distributed systems center around distributed and local scheduling of hard real-time tasks with deadline and resource requirements, concurrency control and recovery, and multilevel database security.

In the area of communications network, several projects are under way, including research on coordinated multimedia communications in ISDN, distributed fail-safe routing protocols, and dynamic bandwidth allocation algorithms and distributed computing environment (DCE).

The objective of the current research project (July 1993 to June 1995) includes the finding of energy-related information that will help the people of Iowa to increase energy efficiency in all areas of their energy use; the investigation of computer- based technologies to catalog, store and deliver this information; and the development of a knowledge-based system to give the people of Iowa easy access to reliable, energy-related information.

The main goal of this continuation project (July 1995 to June 1996) is to continue the maintenance of computer platform and server programs for cataloging, storing, and delivering energy-related information.
