Real-Time Object-Oriented Research Group

What do we do ?

Real-time CORBA: Recently the group has been instrumental in the design of the OMG's Realtime CORBA 1.0 Scheduling Service specification. The group has also worked with TriPacific Software to provide an interface between the PERTS real-time analysis software and the Realtime CORBA 1.0 scheduling service. This new work combines previous work involving expression and enforcement of timing constraints in a non-real-time ORB, with the fixed priority scheduling work. Papers describing Real-Time CORBA research can be found here.
Real-Time Object-Oriented Databases: This work includes real-time semantic concurrency control, object-oriented extensions to the well-known priority ceiling protocols, value-based scheduling algorithms, and prototyping as an extension to the Open-Object-Oriented Database System from Texas Instruments. Papers describing the RTOODB research can be found here.
Distributed Real-Time Collaborative Services: This work involves representing real-time data in a distributed collaborative environment, communicating via real-time CORBA, scheduling requests within the virtual environment based on multiple criteria, using real-time agents to automatically perform tasks for collaborating users, and utilizing a real-time database to store the real-time data. Papers describing the DRTCS research can be found here.

Real-Time SQL: Real-time extensions to the ANSI/ISO standard SQL database query language were developed by the URI real-time object-oriented research group in conjunction with researchers at the University of Masschusetts/Dartmouth, East Carolina University and the US Navy's Next Generation Computer Resources Program. Papers describing the Real-Time SQL research can be found here.
