In this paper we will propose a novel distributed architecture for overlay tree construction in collaborative virtual environments that is unlimitedly scalable due to its fully decentralized nature. The routing issue over this architecture will later be discussed and several forwarding schemes based on distributed hash tables (DHT) will be proposed. One of the main concerns for a routing algorithm...
In this paper, we introduce a framework that supports a large number of participants in a collaborative virtual environment (CVE). We consider object classification based on avatars' physical characteristics to define the overlay network used to disseminate update messages between participants. This concept systematically puts objects into different logical clusters where each cluster can be rated...
One of the known problems with shared object manipulation in collaborative virtual environments (CVE) is the disruptive effect of network lag in collaboration sessions. It is widely recognized that delay and jitter cause significant problems for CVEs. Most solutions to this problem revolve around techniques to compensate for this lag at the networking level. More recently, the usage of visual cues...
