Interconnection model for networked virtual reality applications

Specification of networking requirements for networked virtual reality applications and a way of propagating the user/application level requirements down to the communication level are open research issues. As a contribution to ongoing research, we propose a model, named interconnection model, that represents a network-oriented view of a distributed virtual environment. Within the model, bandwidth requirements are addressed in more detail for shared virtual objects that change as a result of user interactions. A prototype multi-user distributed virtual environment for teleoperation of a mobile robot has been used as a case study.
