ITTC Project

Architecture and Prototype of an Ambient Computational Environment (ACE) [DARPA]

Project Award Date: 06-29-2000


This 2.5-year effort complements ITTC's significant and ongoing work in the field of ambient computational environments, also known as ACE.

In a computational environment, access to equipment such as computers, cameras, video players, projectors, or cell phones is embedded into a room through a network that links them to one another and to other rooms or buildings on the network. These tools can then be controlled or accessed from anywhere along the network. So, instead of carrying a laptop, cell phone, and pager to a meeting, a person could access his or her files and phone messages from equipment found anywhere along a network.

"We're starting with the idea that computation resourcesin the broadest senseare readily available in our offices, conference rooms, auditoriums, and even hallways," said Joe Evans. Any authorized person can then access those computer resources for his or her own use in a variety of ways.

"For example," said Evans, "imagine that the computer you've been working at for 497 days is going to be swapped out for a newer model." The very thought, he noted, would panic most people. Will all the files transfer? Will the software work right? Will the changeover cost valuable time?

"But if your computer is linked to an ACE network, a technician arrives with your new equipment and unplugs your display, keyboard, and computer. He ignores the fact that your desk computer is running, because that computer simply is a port to the larger network. When the installer leaves and you identify yourself to your new machine, you continue on with your work. Tomorrow your computer will show 498 working days." A long-lived and robust ACE network, not a piece of hardware, becomes the computational heart of an office.

As part of their DARPA project, Minden and Evans will also study the impact ACE will have on high-performance networking systems. "ACE will create a different type of traffic along the networks," said Minden. "We need to know what must be done to secure the transmission of ACE content over widely distributed, next generation Internets."

The DARPA funds primarily will support student salaries and equipment.

Partner with ITTC

The Information and Telecommunication Technology Center at the University of Kansas has developed several assistance policies that enhance interactions between the Center and local, Kansas, or national companies. 

ITTC assistance includes initial free consulting (normally one to five hours). If additional support is needed, ITTC will offer one of the following approaches: 

Sponsored Research Agreement

Individuals and organizations can enter into agreements with KUCR/ITTC and provide funds for sponsored research to be performed at ITTC with the assistance of faculty, staff and students.

Licensing and Royalty/Equity Agreement

An ITTC goal is the development of investment-grade technologies for transfer to, and marketing by, local, Kansas, and national businesses. To enhance this process, the Center has developed flexible policies that allow for licensing, royalty, and equity arrangements to meet both the needs of ITTC and the company.

Commercialization Development

Companies with a technology need that can be satisfied with ITTC's resources can look to us for assistance. We can develop a relationship with interested partners that will provide for the development of a technology suited for commercialization.

ITTC Resource Access

ITTC resources, including computers and software systems, may be made available to Kansas companies in accordance with the Center's mission and applicable Regents and University policies.
