A virtual world is an artificial environment, created inside a computer,
which mimics some aspect of the real world. Virtual worlds are often
multiuser, which means that many people may be present in the virtual
world simultaneously and may interact with each another and the virtual
environment. With the advent of the global Internet connectivity, users from
all over the real world may participate in multiuser virtual worlds and
interact without any regard for geographic boundaries.
However, achieving believable realism is not easy and there are several factors
which can hinder a user's virtual world experience. In order to avoid
these kinds of problems and provide the best possible experience, the
underlying network must be designed and implemented carefully.
This thesis presents a tool which can guide the design and implementation of
virtual world systems to avoid potential problems. This is achieved by
simulating the system in various scenarios and evaluating the performance of
the system and the potential solutions.
