ABSTRACT
Distributed Virtual Environment systems allow multiple users, working on different client computers interconnected through different networks, to interact in a shared virtual world. In these systems, latency is crucial for providing an acceptable quality of service, since it determines how fast client computers are reported about changes in the shared virtual scene produced by other client computers.This paper presents, in a unified manner, a partitioning approach for providing a latency below a threshold to the maximum number of users as possible in Distributed Virtual Environment systems. This partitioning approach searches the assignment of avatars that represents the best trade-off among system latency, system throughput, and partitioning efficiency when solving the partitioning problem. Evaluation results show that the proposed approach not only maximizes system throughput, but it also allows the system to satisfy, if possible, any specific latency requirement needed for providing quality of service. This improvement is achieved without decreasing neither image resolution nor quality of animation, and it can be used together with other techniques already proposed. Therefore, it can contribute to provide quality of service in Distributed Virtual Environments.
