Abstract

We present a P2P VoIP conferencing network with a symmetric distributed processing topology that we believe to be well suited for use in auditory virtual environments because it allows for multi-group communication and individual volumes per user. The network provides adaptive quality based on virtual locality while requiring significantly less bandwidth than a full-mesh topology. We also present a clustering algorithm for mapping a virtual scene to such a network structure, minimizing network diameter while respecting virtual locality. We analyzed bandwidth and latency characteristics and verified implementation feasibility by means of discrete event simulation.
