Distributed Virtual Environment systems simulate the
behaviour and activities of a great number of concurrent
users interacting in a virtual world over a wide area
network. The advances both in computer technology and
networking infrastructures in combination to the advanced
applications and services developed, expanded the
popularity of DVEs and promoted their use in a wide range
of areas, such as learning and training, collaborative work,
military applications and multiplayer online games. The
sizes of the virtual worlds simulated and the tremendous
number of users that DVEs are called to support require
additional bandwidth and computational resources. For
handling these growing requirements a lot of work has been
done both to the direction of alternative architectural
solutions as well as to techniques and algorithms for
handling and overcoming the limitations of these
environments. However, recent research has shown that one
of the major limitations of networked servers DVE systems
is scalability. To this direction this paper presents on the one
hand a dynamic approach for DVEs, which exploits the
nature of these systems for the optimal resource
management and extended scalability support and on the
other hand, evaluates its performance through a series of
experiments and under various settings of the virtual world,
using Simul8 simulation tool.
