Network issues with Immersive Collaborative Environments
Network issues with Immersive Collaborative Environments• Timing is essential in the operation of
distributed virtual environment applications, since the perception of changes in the virtual environment is based on the timely delivery of messages, informing all the participants of the changes made by a user.
• Any action issued by any participant must reach the other participants within 200 ms.
• This task, challenging as it is, becomes even more challenging, when dealing with virtual environments with a large number of participants.

Network issues with Immersive Collaborative Environments
Network issues with Immersive Collaborative Environments• The high level of dynamicity in
group structure and topology increases the complexity of the problem.
• Participants might join and leave the session dynamically.
• The requirement that the developed DVE applications will be supporting collaborative functions, makes timing even more important.

In this project, will attempt to: • Identify and quantify the end-system
and network parameters that are crucial to the operation of the virtual reality application;
• Develop technology to support the strict requirements of these applications;
• Use and improve CAVERNsoft*G2, a C++ toolkit for building collaborative networked applications.

• The University of Alberta is proposing to work with industrial partner, BigBangwidth, to experiment and test advanced network connectivity solutions within the WestGrid network.
• The purpose of the project is to provide researchers, high-bandwidth access to the WestGrid network to enable effective grid computing applications, especially visualization
• This project is part of a 2M$ WED grant that will be hopefully funded at the beginning of next year.
