Distributed Virtual Environments (DVEs) have been widely used in online games, military training and collaborative engineering applications, etc. In DVEs, the primary task is to maintain a consistent view of the virtual world among all users. Multi-server architecture has been shown to have good scalability to support a large population of users in DVEs. However, servers can still get saturated with...
The primary task of distributed virtual environments (DVEs) is to maintain a consistent view of the virtual world among all users. Multi-server architecture has been shown to have good scalability to support a large population of users in DVEs. However, some of the servers' resources like CPU, memory and network bandwidth can still get saturated as the scale of DVE increases. In this case, state updates...
Spatial filtering is an interest management mechanism that eliminates unnecessary state updates transmitted in distributed virtual environments. This paper proposes a new protocol to reduce the communication overhead for supporting spatial filtering. The protocol maintains potential interest regions (PIRs) to assist in observing entities entering the areas-of-interest (AOIs) of other entities. PIRs...
