In Distributed Virtual Environments (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. In thezone-based Multi-server Distributed Virtual Environment (MSDVE), zone mapping and client assignment are two key issues in the design of an efficient...
By sharing resources among peers in peer-to-peer network, application layer multicast (ALM) has been shown an efficient way to improve the scalability and reduce the latency of communication. To deploy ALM in peer-to-peer distributed interactive applications (DIAs), the property of many-to-many communication of DIA demands multiple multicast trees to be constructed in the overlay. Therefore, how to...
Due to diverse network latencies, participants in a Distributed Virtual Environment (DVE) may observe different inconsistency levels of the simulated virtual world, which can seriously affect fair competition among them. In this paper, we investigate how to disseminate Dead Reckoning (DR)-based updates with the objectives of achieving fairness among participants and reducing inconsistency as much...
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. One of the key issues in the design of an efficient and scalable Multi-server Distributed Virtual Environment (MSDVE) is the partitioning, which concerns with efficiently distributing the workload...
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...
In distributed virtual environments (DVEs), maintaining a consistent view of the virtual world among all users is a primary task. Due to the resource limitations such as network capacity and computational power, the consistency of the virtual world cannot be guaranteed sometimes. In this paper, we try to address this problem in client-server-based DVEs by considering server side network capacity limitation...
An Interest Management (IM) mechanism eliminates irrelevant status updates transmitted in Networked Virtual Environments (NVE). However, IM itself involves both computation and communication overhead, of which the latter is the focus of this paper. Traditionally, there are area-based and cell-based IM mechanisms. This paper proposes a hybrid IM mechanism for peer-to-peer NVEs, that utilizes the cell-based...
