  7. Abstract:
  8. Multi-participant virtual environments are network applications that simulate the experience of real-time interaction among multiple usersdistributed all over the internet In order to share the common sense of time and place, multiple entities interacting in the shared virtual environment should become aware of the modification to the shared environment, or the result of on the other objects interactions shortly after such events occur. This is achieved through the distribution of update messages. As the number of users and entities increases, there is a considerable increase in the amount of update messages exchanged among the users and entities. This is considered as one of the most important challenges in the design of large scale virtual environments. The use of distributed architectures is a solution to this problem. However, such architectures should in teurn deal with a variety of challenges related to noncentralized protocols. This dissertation proposes a number of distributed architectures for massively multi user virtual environments in an attempt to provide an efficient infrastructure for update message distribution. Simulation has also been used to demonstrate the functality and performance of the proposed approaches.
