A novel method for supporting massively multi-user virtual environments

In collaborative distributed virtual environment people interact with each other to shard their states. In this paper we present massively multi-user virtual simulation architecture-MM-VISA. The framework partitions the simulation platform into multiple regions to properly organize the decorative entities and to efficiently manage their association. The coordinator. the leader of a zone, manages local communications in multicast fashion but this multicast functionality is shifted from the network layer to the application layer to get the benefit of the scalability and easy deploy-ability. Considering the behavior of the entities, coordinator opens multiple multicast channels to reduce structural reformation events among the entities. On the other hand, coordinators themselves form a top level mesh hierarchy to manage the area of interest. A mathematical model is given to determine the best node in the best zone with a given interest vector. This gives a provision to a node to import all the interesting messages when needed and makes it easy to be virtually there.
