Distributed Virtual Environments (DVEs) allow many
simultaneous human users to interact with each other in
shared, 3D virtual worlds. The interactivity of a DVE is of
crucial importance, as its success greatly depends on users’
perceptions when interacting within the virtual world. In
this paper, different from traditional application-centric approaches
like dead reckoning, we propose a network-centric
approach to enhance the interactivity of DVEs by directly
reducing the network latencies in client-server communications.
We consider a key problem with this approach, termed
the server placement problem. Generally, this problem concerns
how to place servers in the network to reduce clientserver
communication latencies. We then suggest several
degree-based server placement approaches. Extensive simulation
studies using realistic models have shown that appropriate
server placement is very effective in enhancing
the interactivity of large-scale DVEs.
